RFID = Radio Frequency Identification. Probably a poor choice for a security system.

Use Google and look around . There's lots to read and you can buy introduction kits too.
RFID is just a big number that is read by the reader and no power is used by the device only the reader.

Here is an access control system using RFID 125KHz chips. L1-1 and L1-2 in the schematic are the terminals for the coil .

RFID chips have unique serial numbers similar to I-buttons which are used for control.

If you are interested in building the circuit please PM me your email address. I'll send you the hexfile for the MCU and also single sided PCB design.
