RE: NFC Lock — run with NFC Tag Antenna

I'm also working on something NFC related. How can you read an NFC tag in a ball that might be placed any way up?

The answer: multiple antennas at different angles and switching between them. The theory is sound, but unfortunately I can't get an adequate read range. (The antennas need to be small as there's going to be other stuff around the outside too.)

Nice to see the new NXP LPC55S69 dev board being put to good use.

I don't want to get bogged down on terminology, but technically 125kHz is classed as low frequency (LF) RFID, while NFC is seen as a higher frequency (HF) subset of RFID, operating only at 13.56MHz.
