RFID systems have an RFID tag or smart label, an RFID reader, and an antenna. The RFID tag uses an integrated circuit and an antenna, which to transmit data to an RFID reader.&nbsp; Both the RFID readers and the tag must be tuned to the same frequency to communicate.&nbsp; NFC is a branch of High-Frequency (HF) RFID, both operate at the 13.56 MHz frequency. NFC protocol is used for secure form of data exchange, with an NFC device is capable of being both an NFC reader and an NFC tag. NXP is a co-inventor of NFC along with Sony and supplies the chip that enables your smart phone to make contactless payments, store, and exchange goods securely.&nbsp; </span></p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;"><span style="color:#333333;font-family:Arial, &#39;Lucida Grande&#39;, sans-serif;">Because voting was very deadlocked between three of the top four winners, they all get shopping carts.&nbsp; The clear winner, <a class="jive-link-blog-small" href="/challenges-projects/project14/nfc-rfid/b/blog/posts/locknfc">LockNFC</a> by <span><a href="/members/fred27">Fred27</a></span> , an NFC/keypad lock with many uses such as the garage and the front door.&nbsp; It had a professional look and we assume it passed WAF (Wife Acceptance Factor). <a class="jive-link-blog-small" href="/challenges-projects/project14/nfc-rfid/b/blog/posts/s-h-e-l-f-v2">S.H.E.L.F.

A loftier goal was to make something that fitted my front door. His requirements were that it must look professional with no dangling wires or bits duct taped to the back of the door, it must be possible to still use the normal key to open the door, any electronic failure must mean the door can be operated normally, and as you may have guessed there was the WAF&nbsp; (Wife Acceptance Factor).&nbsp; For the PCB design he wanted an NFC reader that was tuned to his NFC implant and which also included a keypad for his (unmodified) kids to use.&nbsp; After waiting for the PCB to arrive from Seed, it was time to populate it, run it through the toaster oven and see if there were any mistakes made. As usual, QFN soldering of the TRF7970A NFC transceiver was a struggle. The final result looks professional enough with the naked eye even if the process certainly wasn&#39;t. You can&#39;t really test the hardware without some firmware running on the microcontroller, so he quickly adapted my test code from the development board. It wasn&#39;t too long until he had the capacitive touch button code running and working. Then he got the NFC code reading an NFC tag. It&#39;s all very well deciding that the PCB itself will be the front panel for the lock, but it will still need an enclosure. He decided to tackle the simplest lock first - and that was his garage door. The reason for this is that all he has to do is simulate a button press, At worst a relay across the existing push-button would do. Of course, that still leaves the issue of how to mount it outside the garage. Once again, this is probably the simplest use case. He can go with a 3D printer box and route the cable straight through the single-skin brickwork of my garage. Being a coder at heart, his tool of choice for 3D modelling is OpenSCAD. It&#39;s very different from the more artistic modelling tools, but particularly suits a parametric design.&nbsp; He has a &quot;normal&quot; UK lock or nightlatch on the front door. They work pretty well, but it’s a little trickier to attach a motor to what appears to be a more common lock in the US - the deadbolt.</p><p style="margin:0;padding:0px;">&nbsp;</p><table border="0px" class="jiveBorder" style="border:0px solid #ffffff;width:100%;"><thead><tr><th colspan="2" style="border:0pxpx solid black;border:0px solid #ffffff;padding:6px;color:#ffffff;background-color:#9ea900;text-align:left;" valign="middle"><strong>LockNFC</strong></th></tr></thead><tbody><tr><td colspan="1" style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/438x329/__key/communityserver-wikis-components-files/00-00-00-02-95/5850.contentimage_5F00_117318.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/5850.contentimage_117318.jpg-438x328.jpg?sv=2016-05-31&amp;sr=b&amp;sig=F2%2FWJYZ5O8bpOXzM4ouC0qng7XpTxrXnIzVOng7yZxU%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=zku+Ae69Zm24hsGGb/E/PA==" style="max-height: 328px;max-width: 438px;" /></a></span></td><td colspan="1" style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/584x329/__key/communityserver-wikis-components-files/00-00-00-02-95/8078.contentimage_5F00_117319.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/8078.contentimage_117319.jpg-584x328.jpg?sv=2016-05-31&amp;sr=b&amp;sig=cIZOt9%2Bie3P%2B6Wdr3%2F%2Blnofk4kJ%2FszK2sQ2v2w%2FVDno%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=U/cHoPIHae5So1egutqozg==" style="max-height: 328px;max-width: 584px;" /></a></span></td></tr><tr><td style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/435x326/__key/communityserver-wikis-components-files/00-00-00-02-95/6835.contentimage_5F00_117320.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/6835.contentimage_117320.jpg-435x326.jpg?sv=2016-05-31&amp;sr=b&amp;sig=fsTv%2F6Bm1V%2Fj3KmQc8uxz5Ht2JiP4hsJQsi6HCHBscQ%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=FtSEK44Qs3Uw5LSEMrEuhg==" style="max-height: 326px;max-width: 435px;" /></a></span></td><td style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/433x325/__key/communityserver-wikis-components-files/00-00-00-02-95/2234.contentimage_5F00_117321.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/2234.contentimage_117321.jpg-433x324.jpg?sv=2016-05-31&amp;sr=b&amp;sig=PblVB65GvkJxaxTixhDUy%2FL97WFyxsaMAyF1XyIET%2F8%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=VHUFje6Gz7cFkIwy8Xo3jg==" style="max-height: 324px;max-width: 433px;" /></a></span></td></tr></tbody></table><blockquote class="jive-quote"><p style="margin:0;"><strong>&quot;LockNFC was an innovative project that successfully overcame several engineering challenges. <span><a href="/members/fred27">Fred27</a></span>&nbsp; gave clear step-by-step instructions in a well-written series of blogs, complete with photos and videos.

The idea was having specially designed labels on the top of all of the containers which the camera would recognize. While he still likes the concept, it requires quite a bit of work to get it to any decent level. For the V2, the plan is to use RFID stickers and RFID tags to identify the containers/items. Last time he used a Raspberry as the brain, this time, he will be switching to an Arduino Mega 2560 and an ESP8266-07. He doesn’t need the image processing that he needed in V1 so he can live with something much lower powered, which will be easier to develop, and easier to interface with all of the sensors.

The proposed solution is titled “While You Were Away” because it was intended to “sense” when the user is away and optimize consumption in his/her absence.

The electronic Visitor Book Interface is known as the Visitor “box”.&nbsp; The visitor’s box is made up of 3 development modules, namely the PN7150 controller, the PSoC 4 M0 / BLE module and the ESP8266 WiFi module.&nbsp; It was tidier to have the three development modules inside a box as it would allow him to evaluate the visuals using just a RGB LED as the user interface and a blue LED for connectivity status, hence it is now inside a semi-sealed plastic enclosure. The Visitor&#39;s &quot;box&quot; is powered via USB (5V) through the PSoC 4 BLE Pioneer Baseboard. He hacked the PN7150 Arduino shield to add in a UART interface for the ESP8266. It was rather fortunate that the 2nd PSoC 4 UART block pins were located just where I needed them. The PSoC 4 and the ESP8266 reset pins were connected to ensure a sequenced reboot.</p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;">There are two lots of firmware for the project.&nbsp; The main firmware for the PSoC 4 BLE module was developed using PSoC Creator 4.2 and the other firmware for the ESP8266 WiFi module was developed using the Arduino IDE. As we all should know by now, a common electronic format for storing business card or contact details is in a contacts list, which you will find on all phones and email systems. The contacts list data structure or data format has been around for eons as those who can still recall sharing contact details with Microsoft Outlook back in the day.</p><p style="margin:0;padding:0px;">&nbsp;</p><table border="0px" class="jiveBorder" style="border:0px solid #ffffff;width:100%;"><thead><tr><th colspan="2" style="border:0pxpx solid black;border:0px solid #ffffff;padding:6px;color:#ffffff;background-color:#9ea900;text-align:left;" valign="middle"><strong>NOVSIS</strong></th></tr></thead><tbody><tr><td colspan="1" style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/463x311/__key/communityserver-wikis-components-files/00-00-00-02-95/4784.contentimage_5F00_117333.png"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/4784.contentimage_117333.png-463x311.png?sv=2016-05-31&amp;sr=b&amp;sig=VOg7V%2Bw99quEveCugU3MSRSyFiLJiB2wAbS5%2FWHB%2FCg%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=gYYgdCvTcG0+VdVym0CVeQ==" style="max-height: 311px;max-width: 463px;" /></a></span></td><td colspan="1" style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/396x297/__key/communityserver-wikis-components-files/00-00-00-02-95/1641.contentimage_5F00_117334.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/1641.contentimage_117334.jpg-396x297.jpg?sv=2016-05-31&amp;sr=b&amp;sig=9g2Yucwe8GolZYmhq%2BHNYn9SKB6rMBZgVAn05904mM8%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=XP4+zupRdV4yZ8qTQ7zkhw==" style="max-height: 297px;max-width: 396px;" /></a></span></td></tr><tr><td style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/271x359/__key/communityserver-wikis-components-files/00-00-00-02-95/1145.contentimage_5F00_117335.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/1145.contentimage_117335.jpg-271x358.jpg?sv=2016-05-31&amp;sr=b&amp;sig=AaI%2BCH0%2BUZa5CBNOq43zyZl1Hb9JjyI8xzN9gDKQHkU%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=29MEa4PrnN1zsJYHlUs2dA==" style="max-height: 358px;max-width: 271px;" /></a></span></td><td style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/475x356/__key/communityserver-wikis-components-files/00-00-00-02-95/2804.contentimage_5F00_117336.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/2804.contentimage_117336.jpg-475x356.jpg?sv=2016-05-31&amp;sr=b&amp;sig=23tRCMOap5ZDcY7VCskEQgr5WZfnZCi%2BAPc2WN8wy1w%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=Jfk7LEi4IRY2f8JbyB5p1w==" style="max-height: 356px;max-width: 475px;" /></a></span></td></tr></tbody></table><blockquote class="jive-quote"><p style="margin:0;"><strong>&quot;This pipped the others for me as it was a complete build using lots of interesting technology.

RFID systems have an RFID tag or smart label, an RFID reader, and an antenna. The RFID tag uses an integrated circuit and an antenna, which to transmit data to an RFID reader.&nbsp; Both the RFID readers and the tag must be tuned to the same frequency to communicate.&nbsp; NFC is a branch of High-Frequency (HF) RFID, both operate at the 13.56 MHz frequency. NFC protocol is used for secure form of data exchange, with an NFC device is capable of being both an NFC reader and an NFC tag. NXP is a co-inventor of NFC along with Sony and supplies the chip that enables your smart phone to make contactless payments, store, and exchange goods securely.&nbsp; </span></p> <p style="margin:0;padding:0px;">&nbsp;</p> <p style="margin:0;"><span style="color:#333333;font-family:Arial, &#39;Lucida Grande&#39;, sans-serif;">Because voting was very deadlocked between three of the top four winners, they all get shopping carts.&nbsp; The clear winner, <a class="jive-link-blog-small" href="/challenges-projects/project14/nfc-rfid/b/blog/posts/locknfc">LockNFC</a> by <span><a href="/members/fred27">Fred27</a></span> , an NFC/keypad lock with many uses such as the garage and the front door.&nbsp; It had a professional look and we assume it passed WAF (Wife Acceptance Factor). <a class="jive-link-blog-small" href="/challenges-projects/project14/nfc-rfid/b/blog/posts/s-h-e-l-f-v2">S.H.E.L.F.

A loftier goal was to make something that fitted my front door. His requirements were that it must look professional with no dangling wires or bits duct taped to the back of the door, it must be possible to still use the normal key to open the door, any electronic failure must mean the door can be operated normally, and as you may have guessed there was the WAF&nbsp; (Wife Acceptance Factor).&nbsp; For the PCB design he wanted an NFC reader that was tuned to his NFC implant and which also included a keypad for his (unmodified) kids to use.&nbsp; After waiting for the PCB to arrive from Seed, it was time to populate it, run it through the toaster oven and see if there were any mistakes made. As usual, QFN soldering of the TRF7970A NFC transceiver was a struggle. The final result looks professional enough with the naked eye even if the process certainly wasn&#39;t. You can&#39;t really test the hardware without some firmware running on the microcontroller, so he quickly adapted my test code from the development board. It wasn&#39;t too long until he had the capacitive touch button code running and working. Then he got the NFC code reading an NFC tag. It&#39;s all very well deciding that the PCB itself will be the front panel for the lock, but it will still need an enclosure. He decided to tackle the simplest lock first - and that was his garage door. The reason for this is that all he has to do is simulate a button press, At worst a relay across the existing push-button would do. Of course, that still leaves the issue of how to mount it outside the garage. Once again, this is probably the simplest use case. He can go with a 3D printer box and route the cable straight through the single-skin brickwork of my garage. Being a coder at heart, his tool of choice for 3D modelling is OpenSCAD. It&#39;s very different from the more artistic modelling tools, but particularly suits a parametric design.&nbsp; He has a &quot;normal&quot; UK lock or nightlatch on the front door. They work pretty well, but it&rsquo;s a little trickier to attach a motor to what appears to be a more common lock in the US - the deadbolt.</p> <p style="margin:0;padding:0px;">&nbsp;</p> <table class="jiveBorder" style="border:0px solid #ffffff;width:100%;" border="0px"> <thead> <tr> <th style="background-color:#9ea900;border:0px solid #ffffff;color:#ffffff;padding:6px;text-align:left;" colspan="2" valign="middle"><strong>LockNFC</strong></th> </tr> </thead> <tbody> <tr> <td style="border:0px solid #ffffff;padding:6px;width:50%;" colspan="1"><span><a href="https://community.element14.com/resized-image/__size/438x329/__key/communityserver-wikis-components-files/00-00-00-02-95/5850.contentimage_5F00_117318.jpg"><img alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/5850.contentimage_117318.jpg-438x329.jpg?sv=2016-05-31&amp;sr=b&amp;sig=jBR301dM7zza01VHbdlSnjO4a8dOx%2FOCCYpfcrigHn8%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=UdvNylPKct7vr71cfix6dg==" style="max-height: 329px;max-width: 438px;" /></a></span></td> <td style="border:0px solid #ffffff;padding:6px;width:50%;" colspan="1"><span><a href="https://community.element14.com/resized-image/__size/584x329/__key/communityserver-wikis-components-files/00-00-00-02-95/8078.contentimage_5F00_117319.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/8078.contentimage_117319.jpg-584x329.jpg?sv=2016-05-31&amp;sr=b&amp;sig=F2ZDajd%2FbaYQMJPjV%2Bm6DvK2MMWEiFGGKfLreElym%2Bc%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=BRDdT6LcPUBsDIcEmTQxKg==" style="max-height: 329px;max-width: 584px;" /></a></span></td> </tr> <tr> <td style="border:0px solid #ffffff;padding:6px;width:50%;"><span><a href="https://community.element14.com/resized-image/__size/435x326/__key/communityserver-wikis-components-files/00-00-00-02-95/6835.contentimage_5F00_117320.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/6835.contentimage_117320.jpg-435x326.jpg?sv=2016-05-31&amp;sr=b&amp;sig=fsTv%2F6Bm1V%2Fj3KmQc8uxz5Ht2JiP4hsJQsi6HCHBscQ%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=FtSEK44Qs3Uw5LSEMrEuhg==" style="max-height: 326px;max-width: 435px;" /></a></span></td> <td style="border:0px solid #ffffff;padding:6px;width:50%;"><span><a href="https://community.element14.com/resized-image/__size/433x325/__key/communityserver-wikis-components-files/00-00-00-02-95/2234.contentimage_5F00_117321.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/2234.contentimage_117321.jpg-433x325.jpg?sv=2016-05-31&amp;sr=b&amp;sig=f1n38aSvOk8C0XdmXAV%2Fz0LR2v%2FUWvKaXrqdty8plo0%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=dhINdrw/bzLoaFd66zBv+Q==" style="max-height: 325px;max-width: 433px;" /></a></span></td> </tr> </tbody> </table> <blockquote class="jive-quote"> <p style="margin:0;"><strong>&quot;LockNFC was an innovative project that successfully overcame several engineering challenges. <span><a href="/members/fred27">Fred27</a></span>&nbsp; gave clear step-by-step instructions in a well-written series of blogs, complete with photos and videos.

The idea was having specially designed labels on the top of all of the containers which the camera would recognize. While he still likes the concept, it requires quite a bit of work to get it to any decent level. For the V2, the plan is to use RFID stickers and RFID tags to identify the containers/items. Last time he used a Raspberry as the brain, this time, he will be switching to an Arduino Mega 2560 and an ESP8266-07. He doesn&rsquo;t need the image processing that he needed in V1 so he can live with something much lower powered, which will be easier to develop, and easier to interface with all of the sensors. The ESP8266-07 will be used to upload data online so he can later access it using my phone. Last time he used a third party app which showed the value, but didn&#39;t have the interface he wanted, so this time he will be making a simple Android app which can read data from ThingSpeak.</p> <p style="margin:0;padding:0px;">&nbsp;</p> <table class="jiveBorder" style="border:0px solid #ffffff;width:100%;" border="0px"> <thead> <tr> <th style="background-color:#9ea900;border:0px solid #ffffff;color:#ffffff;padding:6px;text-align:left;" colspan="2" valign="middle"><strong>S.H.E.L.F.

The electronic Visitor Book Interface is known as the Visitor &ldquo;box&rdquo;.&nbsp; The visitor&rsquo;s box is made up of 3 development modules, namely the PN7150 controller, the PSoC 4 M0 / BLE module and the ESP8266 WiFi module.&nbsp; It was tidier to have the three development modules inside a box as it would allow him to evaluate the visuals using just a RGB LED as the user interface and a blue LED for connectivity status, hence it is now inside a semi-sealed plastic enclosure. The Visitor&#39;s &quot;box&quot; is powered via USB (5V) through the PSoC 4 BLE Pioneer Baseboard. He hacked the PN7150 Arduino shield to add in a UART interface for the ESP8266. It was rather fortunate that the 2nd PSoC 4 UART block pins were located just where I needed them. The PSoC 4 and the ESP8266 reset pins were connected to ensure a sequenced reboot.</p> <p style="margin:0;padding:0px;">&nbsp;</p> <p style="margin:0;">There are two lots of firmware for the project.&nbsp; The main firmware for the PSoC 4 BLE module was developed using PSoC Creator 4.2 and the other firmware for the ESP8266 WiFi module was developed using the Arduino IDE. As we all should know by now, a common electronic format for storing business card or contact details is in a contacts list, which you will find on all phones and email systems. The contacts list data structure or data format has been around for eons as those who can still recall sharing contact details with Microsoft Outlook back in the day.</p> <p style="margin:0;padding:0px;">&nbsp;</p> <table class="jiveBorder" style="border:0px solid #ffffff;width:100%;" border="0px"> <thead> <tr> <th style="background-color:#9ea900;border:0px solid #ffffff;color:#ffffff;padding:6px;text-align:left;" colspan="2" valign="middle"><strong>NOVSIS</strong></th> </tr> </thead> <tbody> <tr> <td style="border:0px solid #ffffff;padding:6px;width:50%;" colspan="1"><span><a href="https://community.element14.com/resized-image/__size/463x311/__key/communityserver-wikis-components-files/00-00-00-02-95/4784.contentimage_5F00_117333.png"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/4784.contentimage_117333.png-463x311.png?sv=2016-05-31&amp;sr=b&amp;sig=VOg7V%2Bw99quEveCugU3MSRSyFiLJiB2wAbS5%2FWHB%2FCg%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=gYYgdCvTcG0+VdVym0CVeQ==" style="max-height: 311px;max-width: 463px;" /></a></span></td> <td style="border:0px solid #ffffff;padding:6px;width:50%;" colspan="1"><span><a href="https://community.element14.com/resized-image/__size/396x297/__key/communityserver-wikis-components-files/00-00-00-02-95/1641.contentimage_5F00_117334.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/1641.contentimage_117334.jpg-396x297.jpg?sv=2016-05-31&amp;sr=b&amp;sig=9g2Yucwe8GolZYmhq%2BHNYn9SKB6rMBZgVAn05904mM8%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=XP4+zupRdV4yZ8qTQ7zkhw==" style="max-height: 297px;max-width: 396px;" /></a></span></td> </tr> <tr> <td style="border:0px solid #ffffff;padding:6px;width:50%;"><span><a href="https://community.element14.com/resized-image/__size/271x359/__key/communityserver-wikis-components-files/00-00-00-02-95/1145.contentimage_5F00_117335.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/1145.contentimage_117335.jpg-271x359.jpg?sv=2016-05-31&amp;sr=b&amp;sig=fCeDlZvkSdn0b6h25XL576O1koWjDFBIdp%2FbWfMGiiw%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=pVPQKgiR/TSjXYF+Uh2RWQ==" style="max-height: 359px;max-width: 271px;" /></a></span></td> <td style="border:0px solid #ffffff;padding:6px;width:50%;"><span><a href="https://community.element14.com/resized-image/__size/475x356/__key/communityserver-wikis-components-files/00-00-00-02-95/2804.contentimage_5F00_117336.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/2804.contentimage_117336.jpg-475x356.jpg?sv=2016-05-31&amp;sr=b&amp;sig=23tRCMOap5ZDcY7VCskEQgr5WZfnZCi%2BAPc2WN8wy1w%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=Jfk7LEi4IRY2f8JbyB5p1w==" style="max-height: 356px;max-width: 475px;" /></a></span></td> </tr> </tbody> </table> <blockquote class="jive-quote"> <p style="margin:0;"><strong>&quot;This pipped the others for me as it was a complete build using lots of interesting technology.

RFID systems have an RFID tag or smart label, an RFID reader, and an antenna. The RFID tag uses an integrated circuit and an antenna, which to transmit data to an RFID reader.&nbsp; Both the RFID readers and the tag must be tuned to the same frequency to communicate.&nbsp; NFC is a branch of High-Frequency (HF) RFID, both operate at the 13.56 MHz frequency. NFC protocol is used for secure form of data exchange, with an NFC device is capable of being both an NFC reader and an NFC tag. NXP is a co-inventor of NFC along with Sony and supplies the chip that enables your smart phone to make contactless payments, store, and exchange goods securely.&nbsp; </span></p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;"><span style="color:#333333;font-family:Arial, &#39;Lucida Grande&#39;, sans-serif;">Because voting was very deadlocked between three of the top four winners, they all get shopping carts.&nbsp; The clear winner, <a class="jive-link-blog-small" href="/challenges-projects/project14/nfc-rfid/b/blog/posts/locknfc">LockNFC</a> by <span><a href="/members/fred27">Fred27</a></span> , an NFC/keypad lock with many uses such as the garage and the front door.&nbsp; It had a professional look and we assume it passed WAF (Wife Acceptance Factor). <a class="jive-link-blog-small" href="/challenges-projects/project14/nfc-rfid/b/blog/posts/s-h-e-l-f-v2">S.H.E.L.F.

A loftier goal was to make something that fitted my front door. His requirements were that it must look professional with no dangling wires or bits duct taped to the back of the door, it must be possible to still use the normal key to open the door, any electronic failure must mean the door can be operated normally, and as you may have guessed there was the WAF&nbsp; (Wife Acceptance Factor).&nbsp; For the PCB design he wanted an NFC reader that was tuned to his NFC implant and which also included a keypad for his (unmodified) kids to use.&nbsp; After waiting for the PCB to arrive from Seed, it was time to populate it, run it through the toaster oven and see if there were any mistakes made. As usual, QFN soldering of the TRF7970A NFC transceiver was a struggle. The final result looks professional enough with the naked eye even if the process certainly wasn&#39;t. You can&#39;t really test the hardware without some firmware running on the microcontroller, so he quickly adapted my test code from the development board. It wasn&#39;t too long until he had the capacitive touch button code running and working. Then he got the NFC code reading an NFC tag. It&#39;s all very well deciding that the PCB itself will be the front panel for the lock, but it will still need an enclosure. He decided to tackle the simplest lock first - and that was his garage door. The reason for this is that all he has to do is simulate a button press, At worst a relay across the existing push-button would do. Of course, that still leaves the issue of how to mount it outside the garage. Once again, this is probably the simplest use case. He can go with a 3D printer box and route the cable straight through the single-skin brickwork of my garage. Being a coder at heart, his tool of choice for 3D modelling is OpenSCAD. It&#39;s very different from the more artistic modelling tools, but particularly suits a parametric design.&nbsp; He has a &quot;normal&quot; UK lock or nightlatch on the front door. They work pretty well, but it’s a little trickier to attach a motor to what appears to be a more common lock in the US - the deadbolt.</p><p style="margin:0;padding:0px;">&nbsp;</p><table border="0px" class="jiveBorder" style="border:0px solid #ffffff;width:100%;"><thead><tr><th colspan="2" style="border:0pxpx solid black;border:0px solid #ffffff;padding:6px;color:#ffffff;background-color:#9ea900;text-align:left;" valign="middle"><strong>LockNFC</strong></th></tr></thead><tbody><tr><td colspan="1" style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/438x329/__key/communityserver-wikis-components-files/00-00-00-02-95/5850.contentimage_5F00_117318.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/5850.contentimage_117318.jpg-438x329.jpg?sv=2016-05-31&amp;sr=b&amp;sig=jBR301dM7zza01VHbdlSnjO4a8dOx%2FOCCYpfcrigHn8%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=UdvNylPKct7vr71cfix6dg==" style="max-height: 329px;max-width: 438px;" /></a></span></td><td colspan="1" style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/584x329/__key/communityserver-wikis-components-files/00-00-00-02-95/8078.contentimage_5F00_117319.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/8078.contentimage_117319.jpg-584x329.jpg?sv=2016-05-31&amp;sr=b&amp;sig=F2ZDajd%2FbaYQMJPjV%2Bm6DvK2MMWEiFGGKfLreElym%2Bc%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=BRDdT6LcPUBsDIcEmTQxKg==" style="max-height: 329px;max-width: 584px;" /></a></span></td></tr><tr><td style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/435x326/__key/communityserver-wikis-components-files/00-00-00-02-95/6835.contentimage_5F00_117320.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/6835.contentimage_117320.jpg-435x326.jpg?sv=2016-05-31&amp;sr=b&amp;sig=fsTv%2F6Bm1V%2Fj3KmQc8uxz5Ht2JiP4hsJQsi6HCHBscQ%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=FtSEK44Qs3Uw5LSEMrEuhg==" style="max-height: 326px;max-width: 435px;" /></a></span></td><td style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/433x325/__key/communityserver-wikis-components-files/00-00-00-02-95/2234.contentimage_5F00_117321.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/2234.contentimage_117321.jpg-433x325.jpg?sv=2016-05-31&amp;sr=b&amp;sig=f1n38aSvOk8C0XdmXAV%2Fz0LR2v%2FUWvKaXrqdty8plo0%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=dhINdrw/bzLoaFd66zBv+Q==" style="max-height: 325px;max-width: 433px;" /></a></span></td></tr></tbody></table><blockquote class="jive-quote"><p style="margin:0;"><strong>&quot;LockNFC was an innovative project that successfully overcame several engineering challenges. <span><a href="/members/fred27">Fred27</a></span>&nbsp; gave clear step-by-step instructions in a well-written series of blogs, complete with photos and videos.

The idea was having specially designed labels on the top of all of the containers which the camera would recognize. While he still likes the concept, it requires quite a bit of work to get it to any decent level. For the V2, the plan is to use RFID stickers and RFID tags to identify the containers/items. Last time he used a Raspberry as the brain, this time, he will be switching to an Arduino Mega 2560 and an ESP8266-07. He doesn’t need the image processing that he needed in V1 so he can live with something much lower powered, which will be easier to develop, and easier to interface with all of the sensors. The ESP8266-07 will be used to upload data online so he can later access it using my phone. Last time he used a third party app which showed the value, but didn&#39;t have the interface he wanted, so this time he will be making a simple Android app which can read data from ThingSpeak.</p><p style="margin:0;padding:0px;">&nbsp;</p><table border="0px" class="jiveBorder" style="border:0px solid #ffffff;width:100%;"><thead><tr><th colspan="2" style="border:0pxpx solid black;border:0px solid #ffffff;padding:6px;color:#ffffff;background-color:#9ea900;text-align:left;" valign="middle"><strong>S.H.E.L.F.

The electronic Visitor Book Interface is known as the Visitor “box”.&nbsp; The visitor’s box is made up of 3 development modules, namely the PN7150 controller, the PSoC 4 M0 / BLE module and the ESP8266 WiFi module.&nbsp; It was tidier to have the three development modules inside a box as it would allow him to evaluate the visuals using just a RGB LED as the user interface and a blue LED for connectivity status, hence it is now inside a semi-sealed plastic enclosure. The Visitor&#39;s &quot;box&quot; is powered via USB (5V) through the PSoC 4 BLE Pioneer Baseboard. He hacked the PN7150 Arduino shield to add in a UART interface for the ESP8266. It was rather fortunate that the 2nd PSoC 4 UART block pins were located just where I needed them. The PSoC 4 and the ESP8266 reset pins were connected to ensure a sequenced reboot.</p><p style="margin:0;padding:0px;">&nbsp;</p><p style="margin:0;">There are two lots of firmware for the project.&nbsp; The main firmware for the PSoC 4 BLE module was developed using PSoC Creator 4.2 and the other firmware for the ESP8266 WiFi module was developed using the Arduino IDE. As we all should know by now, a common electronic format for storing business card or contact details is in a contacts list, which you will find on all phones and email systems. The contacts list data structure or data format has been around for eons as those who can still recall sharing contact details with Microsoft Outlook back in the day.</p><p style="margin:0;padding:0px;">&nbsp;</p><table border="0px" class="jiveBorder" style="border:0px solid #ffffff;width:100%;"><thead><tr><th colspan="2" style="border:0pxpx solid black;border:0px solid #ffffff;padding:6px;color:#ffffff;background-color:#9ea900;text-align:left;" valign="middle"><strong>NOVSIS</strong></th></tr></thead><tbody><tr><td colspan="1" style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/463x311/__key/communityserver-wikis-components-files/00-00-00-02-95/4784.contentimage_5F00_117333.png"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/4784.contentimage_117333.png-463x311.png?sv=2016-05-31&amp;sr=b&amp;sig=VOg7V%2Bw99quEveCugU3MSRSyFiLJiB2wAbS5%2FWHB%2FCg%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=gYYgdCvTcG0+VdVym0CVeQ==" style="max-height: 311px;max-width: 463px;" /></a></span></td><td colspan="1" style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/396x297/__key/communityserver-wikis-components-files/00-00-00-02-95/1641.contentimage_5F00_117334.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/1641.contentimage_117334.jpg-396x297.jpg?sv=2016-05-31&amp;sr=b&amp;sig=9g2Yucwe8GolZYmhq%2BHNYn9SKB6rMBZgVAn05904mM8%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=XP4+zupRdV4yZ8qTQ7zkhw==" style="max-height: 297px;max-width: 396px;" /></a></span></td></tr><tr><td style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/271x359/__key/communityserver-wikis-components-files/00-00-00-02-95/1145.contentimage_5F00_117335.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/1145.contentimage_117335.jpg-271x359.jpg?sv=2016-05-31&amp;sr=b&amp;sig=fCeDlZvkSdn0b6h25XL576O1koWjDFBIdp%2FbWfMGiiw%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=pVPQKgiR/TSjXYF+Uh2RWQ==" style="max-height: 359px;max-width: 271px;" /></a></span></td><td style="border:0pxpx solid black;border:0px solid #ffffff;width:50%;padding:6px;"><span><a href="https://community.element14.com/resized-image/__size/475x356/__key/communityserver-wikis-components-files/00-00-00-02-95/2804.contentimage_5F00_117336.jpg"><img loading="lazy" alt="image" src="https://community-storage.element14.com/communityserver-components-secureimagefileviewer/communityserver/wikis/components/files/00/00/00/02/95/2804.contentimage_117336.jpg-475x356.jpg?sv=2016-05-31&amp;sr=b&amp;sig=23tRCMOap5ZDcY7VCskEQgr5WZfnZCi%2BAPc2WN8wy1w%3D&amp;se=2026-06-12T23%3A59%3A59Z&amp;sp=r&amp;_=Jfk7LEi4IRY2f8JbyB5p1w==" style="max-height: 356px;max-width: 475px;" /></a></span></td></tr></tbody></table><blockquote class="jive-quote"><p style="margin:0;"><strong>&quot;This pipped the others for me as it was a complete build using lots of interesting technology.
