I purchased an RFID evaluation kit from a company, and I want to develop an access-control door using that RFID system. Unfortunately, it can only be used with a computer via USB. How can I solve this problem?
I’m afraid there is not much you can do. You will need to purchase an RFID reader designed for access-control purposes. You should probably look for a model that is Wiegand-compliant or has a Wiegand interface. Wiegand is a common interface used to connect an RFID reader to an electronic entry system. Wiegand-compatible RFID readers at a doorway connect to a Wiegand-compatible security panel. You can find instructions on the Internet.
