The RFID card is probably just a fixed number and the reader/door locks are all connected back to a central computer. When you swipe the card over a reader the number is read and sent back to the central PC and it decides if the number on your card is valid and then sends the unlock command back to the door.
Don't PM me for help as I will ignore it.
