Description

The MFRC522 RFID module is a highly integrated reader/writer IC for contactless communication at 13.56 MHz.

The original Philips RC522 RFID Module design circuit card reader is easy to use and low cost, and applies to the user equipment development, the reader and the development of advanced applications, and the need for the user RF card terminal design/production. This RC522 RFID Module can be directly loaded into various reader modules. It utilizes a voltage of 3.3V, through the SPI interface with simply a few wires. Directly connected with a CPU motherboard, the module can work in a stable and reliable manner as a distance card reader.
