RFID MFRC-522 RC522 Card Reader Detector Module

The MFRC-522 is a highly integrated reader/writer IC for contactless communication at 13.56 MHz. It is based on the MFRC-530 chip, but with a smaller form factor and a simpler pinout.

It is commonly used with the Arduino platform to read and write data to RFID tags. The MFRC-522 communicates with the Arduino using the SPI protocol. The library for the MFRC-522 is available on Arduino's library manager and can be easily installed. Additionally, You can also find a sample sketch or example code in the library showing the basic functions of the MFRC-522 module like reading and writing to a RFID card.

It is a low-cost, low-power consumption, and small size make it perfect for use in various applications such as access control, inventory tracking, and personal identification.
