Description

The RC522 RFID Card Reader Module is a versatile and reliable solution for adding RFID (Radio-Frequency Identification) capability to your electronics projects. With a working frequency of 13.56MHz, this module allows you to read RFID cards and tags, making it ideal for applications such as access control, attendance systems, inventory management, and more. The MFRC522 is a highly integrated reader/writer IC for contactless communication at 13.56 MHz
RC522 is the highly integrated RFID card reader which works on non-contact 13.56mhz communication, is designed by NXP as low power consumption, low cost and compact size read and write chip, is the best choice in the development of smart meters and portable hand-held devices.
MF RC522 use the advanced modulation system, fully integrated at 13.56MHz with all kinds of positive non-contact communication protocols. Support 14443A compatible answer signal. DSP deal with ISO14443A frames and error correction.
