Could you provide more information... like what exactly is the error?
Secondly, those boards are incompatible. The ESP8266 uses 3.3V logic and the RFID shield uses 5V logic... you should use a logic level converter to avoid damaging your board.

The SoftwareSerial library does not work with ESP modules. Use hardware serial instead.

@alex-prosh Thank you for your insight into the problem.
@idanmalul Another option is to use the EspSoftwareSerial library.
I am going to close this issue since there hasn't been much activity on it.
