Description:
The MFRC-522 RC522 RFID RF Card Sensor Module is a compact and affordable 13.56MHz RFID reader/writer module designed for Arduino, Raspberry Pi, ESP32, STM32, PIC, AVR, and other microcontroller platforms. Based on the NXP MFRC522 chip, the module can read and write RFID cards and tags that comply with the ISO/IEC 14443 Type A standard.
This kit usually includes the RC522 reader module, one S50-compatible Fudan RFID card, and one RFID keychain tag, allowing you to begin experimenting immediately without needing additional accessories.
The module communicates through the SPI interface, making it easy to connect to most development boards. It operates at 3.3V and provides fast and reliable RFID communication at a frequency of 13.56MHz. The typical reading distance is between 2 and 5 cm, depending on the card, tag, and surrounding environment.
The included S50 Fudan card and keychain tag each contain a unique ID that can be read by the module. The module can also be used to store and retrieve small amounts of data on compatible RFID cards.
Typical applications include:
- RFID door locks and access control systems
- Employee attendance systems
- Student ID and library systems
- Arduino and Raspberry Pi security projects
- Smart lockers and cabinets
- Cashless payment prototypes
- Parking and gate control systems
- Time attendance machines
- Inventory and asset tracking
- Home automation and smart home projects
The RC522 module is especially useful for building secure entry systems. For example, in your electronics and automation projects, you could use it with an Arduino or ESP32 to create an RFID-controlled door, machine startup system, or access panel for your future manufacturing equipment or indoor farming control room.
The module includes an onboard PCB antenna and clearly labeled pins for easy connection. Since it operates at 3.3V logic, it is directly compatible with Raspberry Pi and ESP32. When using it with a 5V Arduino board such as an Arduino Uno, it is recommended to use 3.3V power and, if needed, level shifting for the SPI signals.
