PIC based RFID reader

microcontroller project : RFID reader based on PICRFID cards are commonly used for access control and bus/train tickets. They are convenient because no direct contact is required to transfer information to and from the card. The card itself is powered by the RFID reader, so there is no battery to change.

For the experiments, He use a HID ISOProx card. These cards are the simplest of all RFID cards as they only stores a single serial number and uses no encryption. The carrier frequency is 125 KHz. For processing the data, the project uses microcontroller PIC 16F628A.

Interesting to build it?
