Introduction
Keyestudio PN532 NFC/RFID Controller Shield based on PN532 chip is used for field communication close to 13.56MHz. This shield is equipped with an onboard antenna, so there is no external antenna coil. It is compatible with SPI, IIC, UART interface to communicate. When using it, directly stack it onto Arduino UNO R3 control board.

Control Method of Interface Mode
There are two sliding switches on the board to select the interface mode:
Test Result
In the experiment, we use SPI communication, and SCK, MI, MO and NSS on the shield is connected with jumper cap. Dial SET0 to L, SET1 to H. After wiring and uploading the code to the board, open the serial monitor, respectively using S50 Fudan card and key chain to test it, you will get the information as the figure shown blow:
