This shield allows your Arduino to control a door lock using an electric strike plate and one of a number of commonly-available RFID modules, and is based on the circuit described in the "RFID Access Control System" project in the book "Practical Arduino".
Note: Does not include the RFID reader module itself. You need to purchase a module separately. We recommend Priority 1 Design as a good source of compatible modules.
Supported reader modules include:
- RFIDREAD-4100
- RFIDREAD-RW
- RFIDREAD-mRW
- RFIDRW-E-TTL
- ID12
- ID20
- RDM630
- RDM880
- HF MultiTag
