PN532 NFC RFID Module V3 Kit — I2C, SPI, and UART Interface
The PN532 is NXP’s most capable NFC/RFID chip, supporting ISO14443A/B, ISO18092 (NFC), and FeliCa standards at 13.56MHz — covering MIFARE Classic, MIFARE Ultralight, NTAG213/215/216 cards, and Sony FeliCa tags in a single module. The V3 kit ships with a DIP switch for selecting I2C, SPI, or UART communication with the host MCU, making it adaptable to any Arduino or ESP32 hardware configuration without desoldering or board modification.

How does PN532 compare to the MFRC522?
The PN532 supports a wider range of card standards (including NFC Forum tags and FeliCa) and offers card emulation and peer-to-peer NFC modes that the MFRC522 lacks. The MFRC522 is simpler and better supported by basic Arduino libraries; the PN532 requires the Adafruit PN532 library but gives access to NFC features needed for mobile phone NFC interaction and NTAG writing.
Best for
Access control systems, contactless payment prototypes, NFC business card reading, NTAG-based product authentication, Arduino door locks, attendance tracking systems, and any project needing to interact with modern NFC-enabled devices or write NFC tags.
