Adafruit PN532 NFC/RFID Controller Shield for Arduino

Using I2C to Communicate with RFID Reader. As mentioned above, it is possible to use I2C instead of SPI in communicating with the RC522 RFID reader module. To enable I2C, we must cut the connection of the trace on the board to pin 1 on the IC. This can be done by drilling a hole on a board as shown by user Renate-USB of the Arduino community.
