MFRC-522 RC522 Card Read Antenna RFID Reader IC Card Proximity Module Key Chain For Arduino

MFRC-522 RC522 Card Read Antenna RFID Reader IC Card Proximity Module Key Chain For Arduino About

Description:

This is RFID Reader/Writer RC522 SPI S50 CARD AND KEYCHAIN which works on non-contact 13.56mhz communication, is designed by NXP as low power consumption, and low cost and compact size read and write chip, is the best choice in the development of smart meters and portable hand-held devices. It uses an 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. This module can fit directly into handheld devices for mass production. The module uses the 3.3V power supply and can communicate directly with any CPU board by connecting through SPI protocol, which ensures reliable work, and good reading distance.
