NFC, RFID and Accessories Modules

NFC and RFID modules enable contactless identification and data exchange between a reader and a passive tag or card. Operating at 13.56MHz, they support ISO 14443 and MIFARE protocols, allowing cards, fobs, and stickers to be read and written via SPI or I2C.

The range includes the widely used RC522 RFID reader module, the more capable PN532 NFC module supporting both read and write operations, and compatible RFID cards, key fobs, and sticker tags.

NFC and RFID modules are used in access control and attendance systems, contactless payment prototypes, library book tracking, inventory management, smart lock builds, STEM education projects exploring wireless identification, and any IoT application requiring a unique identifier from a physical object.
