01 — About

What it does

The RC522 RFID Cards are a set of 13.56MHz contactless smart cards and key fob tags designed to work seamlessly with the RC522 / MFRC522 RFID reader/writer module. Built on the MIFARE Classic 1K standard with ISO/IEC 14443 Type A compliance, these cards provide reliable, non-contact data storage and identification for access control, attendance systems, embedded projects, and IoT applications. Each card features a 1KB EEPROM memory, a 4-byte unique serial number (UID), and supports read/write operations with CRYPTO1 encryption for secure data handling.

Key features

  • 13.56MHz operating frequency

Good to know

  • These cards operate only at 13.56MHz — not compatible with 125kHz RFID systems.
  • Compatible with MIFARE Classic 1K, Ultralight, S70, Pro, and DESFire protocols.
  • Keep cards away from strong magnetic fields and metal surfaces for optimal read range.
  • Do not bend, puncture, or expose cards to excessive heat or moisture.
  • Store in a cool, dry place when not in use to preserve data integrity.
  • Verify reader antenna tuning and positioning for maximum communication distance.
