Card Reader Module RC522 Serial Port Reader 13.56mhz Ic Card RF Module New 1x

ITEM NAME:Card Reader Module RC522 Serial Port Reader 13.56mhz Ic Card RF Module New 1x Descriptio n Description: RFID reader module RC522 serial reader < span class = notranslate '> 13.56 MHZ rf Ic card module describe 1 function 1). MF RC522 applied to < span class = notranslate '> 13.56 MHz contactless card reader communication chip, belongs to the high integration of NXP.It has low voltage, low cost, small size, non-contact chip card reader and other advantages, is the ideal choice of smart meters and portable handheld devices. 2). MF RC522 adopts advanced modem concepts and is fully integrated into various types of passive > 13.56 MHz contactless communication methods and protocols. Support ISO14443A multi - layer applications.The transmitter portion of its internal communications can drive the card reader antenna and ISO 14443A/MIFARE and transponder, with no other circuitry.The receiver part provides robust and efficient demodulation and decoding circuits for processing iso14443a-compatible transponder signals.The digital portion handles ISO14443A frames and error detection (parity and CRC).In addition, it supports fast CRYPTO1 encryption algorithms used to validate MIFARE products.Does Mfrc522 support contactless card readers?High-speed non-contact communication, two-way data transmission rate up to 424kbit/s. 3). As a new member of the highly integrated > 13.56 MHz card reader family of chips, MF RC522 MF RC500 shares many similarities with RC530, but also has many other characteristics and differences.It USES less connection between host and serial port communication, and can choose a mode SPI, I2C or serial port UART(similar to RS232) according to different user needs, which is helpful to reduce connection, PCB board size and cost. 2 applications 1) MF RC522 is suitable for all kinds of non-contact communication based on ISO/IEC 14443A, which requires the application of low cost, small size, high performance and high power single channel. Three table 2) 3.RFID reader module RC522 serial reader < span class = notranslate '> 13.56 MHZ rf Ic card module. Interface: UART TTL. Sleep current :<80uA. Peak current :< 30mA.
