I want to start with the RFID by building up a simple lock which can be unlocked with another RFID transponder.
The device which has unlocks the lock and has one RFID transponder will be a BeagleBone Black. I would like to have the key as some static RFID transponder (sends only its key).
To achieve this I have following questions:
- Is it possible to connect a RFID antenna and control it just with GPIO and PWM or does it necessarily require an own micro controller
- What protocol is used for data communication between the RFID transponders
- Where or how do I set a key on a static RFID transponder
- Are there any resources I should read additionally?
