How It Works
The PN532 communicates wirelessly with compatible 13.56MHz NFC/RFID tags or devices.
A typical project can be configured as:
NFC/RFID Tag → PN532 Module → I2C/SPI/UART → Arduino/ESP32 → Application
For example, an NFC sticker can contain an identification number or stored information. When the sticker is brought close to the PN532 antenna, the module detects and communicates with the tag, allowing the microcontroller to process the received information.
Why Choose the PN532 NFC RFID Module?
- Popular PN532 platform with broad development support
- Supports NFC and 13.56MHz RFID applications
- Multiple communication interfaces
- Suitable for both prototyping and embedded development

Important Note
The PN532 is intended for short-range contactless communication. Actual read/write distance depends on the antenna design, tag type, tag orientation, operating environment, and module version.
Always verify the module's operating voltage and selected communication interface before connecting it to your development board.
