RC522 RFID Reader Writer SPI Module with Card & Tag

Description

Add secure contactless communication and access control to your projects with the RC522 RFID Reader/Writer Module. Operating at the standard 13.56 MHz frequency and utilizing a high-speed SPI interface, this module comes complete with a blank smart card and a keychain fob tag. It is the perfect starting point for building smart locks, attendance systems, and secure IoT devices.

Detailed Description: The RC522 module is based on the highly popular MFRC522 chip, designed to read and write to 13.56 MHz contactless smart cards and tags. It uses an advanced modulation and demodulation concept to establish passive, two-way communication with compatible RFID transponders as soon as they enter its electromagnetic field.

Because it operates natively on 3.3V logic, this module is an exceptionally perfect fit for modern microcontrollers like the ESP32, STM32 Blue Pill, and STM32 Black Pill, requiring no extra logic level converters. It also works easily with standard Arduino Uno setups. Whether you are assembling secure Amaramam Electronics digital design and IoT hardware kits or prototyping a custom physical attendance scanner, this module provides fast and reliable identity verification.

This complete kit includes everything needed to get started immediately: the main RC522 transceiver board, straight and right-angle header pins, one blank standard-sized S50 RFID card, and one convenient S50 keychain fob.

Key Features:

• Complete Kit: Includes the reader/writer module, a blank card, and a keychain tag for immediate testing and deployment.

• High-Speed SPI Interface: Ensures fast data transfer rates and responsive tag detection.

• 3.3V Logic Native: Directly compatible with ESP32 and STM32 microcontrollers without risking overvoltage to the data pins.
