I am trying to interface my raspberry pi to a RFID reader, to make an library management system. I have brought a RFID reader whose data sheet can be found here. I have found a python program which can get data from RFID reader.
I am pretty new to raspbeery pi and not quite sure about how to connect this reader to my pie . As far as I understand, I will have to connect TX , SEL pin to a GP/IO pin as well as Vcc and GND . Do I need to use a voltage shifter to make sure that input voltage level in TX is below 5v. Can anyone guide me on connecting the reader to pi?
