MF RC522 Write/Read Module for Arduino, UART Interface

MF RC522 Write/Read Module have own CPU control, without written protocol, the device via a serial port connection module immediately.
Module fully serial port control (USB/Ethernet turn serial port), without complex SPI, any platform system seamlessly, compatible with any system with the serial port (51 Microcontroller, NPAB, Txuas, Arduino, Windows, li ntawd.)
Only in accordance with the simple command, RFID module can easily operate the IC card reading, writing, add and subtract values (but not modify the IC card ID number)
Module automatically read the IC card ID number ((when energized, the IC card is near, IC card read automatically hexadecimal ID number, ID number issued via a serial port, need not send command)
Modules have multiple instruction and single instruction to read and write functions at the same time, the user can through an instruction is complete to read or write operation.
