Lock with RFID cards
RFID Lock is an electronic lock with wireless RFID cards. In my case, I had RFID reader that works with 125kHz read-only unique cards and a few corresponding cards. RFID reader is ID-12 reader which I got from Elatec. The device has one relay, PIC micro, RFID reader, two pushbuttons, 4 LEDs and a few passives. The lock can remember up to 5 different cards.
