Your module is a cheap 125 kHz RFID module that supports a Serial interface and also provides Wiegand output. You can communicate with it by merely connecting 'V' to 5V, 'G' to GND, and 'TX' to a SoftwareSerial RX pin. It'll spit out the serial number of your RFID tag accompanied with a checksum. Download the library here, follow their instructions and run the basic example to scan a card.
