RC522 RFID Reader Writer Module 13.56MHz SPI Kit for Arduino, Raspberry Pi & ESP32

Build reliable contactless projects with the RC522 RFID Reader Writer Module kit, a compact solution for adding RFID to your prototypes. This 13.56MHz contactless reader/writer communicates with RFID tags and smart cards and ships with the RC522 board, a standard S50 white card, and a keychain tag so you can test immediately. The module uses a standard SPI interface for straightforward wiring to Arduino, Raspberry Pi, ESP32, and other development boards, and works with commonly available libraries for quick integration. Ideal for smart locks, attendance systems, and inventory tracking, the kit provides responsive read/write capability without physical contact, giving makers a practical component for secure access and identification projects.
