Quick Overview
This DIYables RFID kit includes an RC522 reader module with original Philips MFRC522 chip, 1 white S50 RFID card, and 2 key fobs for Arduino, ESP32, ESP8266, and Raspberry Pi projects. The kit operates at 13.56MHz frequency using SPI interface with 3.3V power supply.
The RC522 reader provides reliable contactless tag reading up to several centimeters range. Includes both straight and right-angle pin headers for flexible mounting options. The 3 RFID tags (1 card and 2 key fobs) enable testing multiple user scenarios in access control, attendance tracking, and security applications.
Ideal for building access control systems, smart locks, attendance tracking, security projects, inventory management, and educational RFID/NFC projects. The ISO 14443A protocol ensures compatibility with standard RFID applications.
