PIC's & RFID's

Having another "play" with the PIC System.
Just added an RFID card reader module to it. This comes with a selection of cards to experiment with,
Been writing a simple card entry door lock system.
At the moment it will activate a relay if one specific card is inserted, and turn on the alarm with any other.
The cards all have a unique ID programmed into them. The current system is simple and uses only the first byte of the UID. Using the full one will make it more secure but needs a lot more program code.
