PiFace and RFID for Garage Door Opener

Question

Hello community -

I have an idea for a project and need a few pointers. Let me preface by saying that my background does not include wiring or physics of any kind - NOOB

That being said I have a Model B RasPi, a Wiegand RFID Reader and associated Fob(s) and a PiFace.

I am looking to attach the PiFace to the RFID reader and when there is swipe of a RF fob that matches a database of approved fobs - that the garage door opens. Cool right?

I have one of those keypads - but the buttons stick and its a general pain in the rear.

The RFID reader has the following wires hanging off of it with the descriptions right on the reader -

Red - 5.0-16.0 VDC

Blk-Gnd

Grn-Data0/Data

Wht - Data1/Clock

Drain - Shielded Gnd

Org - Green LED

Brn - Red LED

Yel - Beep

Blu - Hold

So I would obviously need to attach some of these wires to the PiFace - as well as the wires that are currently attached to the keypad to get this working.

Like I said - totally clueless - I am sure I can figure out the Wiegand and code stuff - the wiring itself is where I have no clue

Anyone have any pointers? This is my first real foray into wiring up things like this.

Thanks community.

If you can link in the actual part number I may be able to provide some help I have been developing a cat flap using RFID not much difference between a flap and a garage door (Aside from Size) Peter

Yes I agree but Mike was referring to replacing a keypad rather than a remote

and yes It is possible to have a reader down the drive way a bit on a post or wall depending on surrounding architecture, hopefully Mike has considered this or will now at least.

RFID will only work to a few CM normally unless you go to great expense and install one like they have in stores to detect people stealing goods as they walk through the doors (About 4feet high and 2 - 3 feet wide... )

Another option would be to use an RF transmitter maybe NRF24L01 attached to Arduino look alike or custom board to transmit the code, this is actually quite easy and would solve the range issue and still be cheap to implement
