Those folks at motogadget charge about $40 for their mo.lock (the NFC version) keys–we can do a lot better. And we have : )
The motogadget mo.lock is pretty slick with an idle current usage of 6ma (which is will reduce further as such: 3.2 mA, after 16h 1.5mA, after 8 days 0.75mA), easy installation, +12 vdc compatiblity, and relatively high security compared to literally every other lock using type 2 NTAG transponders.
The catch with mo.lock transponder keys, is that you can’t have NDEF records. Well, technically, you can but phones won’t access them. Memory starting at block 8 up until the config at the end is available–but that only helps advanced users.
What about implants? You’ll all hear more about that in the future.
