Pls,i am working on RFID based access control system using PIC18F4550.I want the users to have access when the RFID tag is display.And there will be an admin that we register any new user.Although am still at the beginning stage.I interfaced the RFID module to the PIC.but instead of displaying the ID of the tag.It is displaying a funny character anytime i connect the RFID RX pin to RX of the PIC.
