RFID card reader module RC522 13.56 MHZ+Tag

The RFID card reader module RC522 is a 13.56 MHz RFID reader and writer based on the NXP MFRC522 chip, supplied with an RFID tag. It reads and writes contactless ISO/IEC 14443 A cards and tags such as MIFARE Classic, and connects to an Arduino, ESP32 or Raspberry Pi over SPI. It is the standard module for door locks, attendance systems and other access control projects.

RFID card reader module RC522 Applications

• RFID door locks and access control with Arduino or ESP32
• Attendance and time logging systems
• Cashless payment and point systems for school projects
• Identifying tools, items or users in automation projects
• Learning about RFID and SPI communication

What's in the Box

• 1 × RC522 RFID reader module
• 1 × 13.56 MHz RFID tag

Tip: Power the module from 3.3 V, not 5 V. With an Arduino Uno and the MFRC522 library, connect SDA to D10, SCK to D13, MOSI to D11, MISO to D12 and RST to D9.
