PN532 NFC RFID Reader Writer Module

The PN532 NFC RFID Reader Writer Module is a versatile near-field communication solution designed for reading and writing contactless smart cards and NFC tags operating at 13.56MHz. Based on the NXP PN532 chipset, this module supports multiple card types including Mifare, ISO14443A/B, and FeliCa, making it compatible with virtually all common NFC tags and cards such as access cards, payment cards, transportation cards, and smartphone NFC.

Featuring three selectable communication interfaces (I2C, SPI, and UART), the module offers maximum flexibility for integration with Arduino, Raspberry Pi, ESP32, and other microcontroller platforms. Simple DIP switches or jumpers allow you to select your preferred interface without soldering. The onboard antenna provides reliable read/write range up to 5-7cm, suitable for most contactless applications while the compact PCB design makes it easy to integrate into projects.

Perfect for building access control systems, attendance systems, smart door locks, contactless payment terminals, inventory management solutions, and interactive NFC-based projects, this module provides both reading and writing capabilities. Whether you’re developing security applications, creating interactive museum exhibits, or experimenting with mobile payment systems, the PN532 module delivers professional-grade NFC functionality with easy-to-use library support for popular platforms.
