Description: This handset can process the data offline or online, reading and writing from 10 cm far. This handset is low-power, miniature, modular design and so on. This article includes: the communication design between RF card and Reader, hardware system design and software systems design. The communication design between RF card and Reader used to RC522 RF chip control RF cards, in line with ISO14443 standard protocol Hardware system design mainly include AVR microcontroller control modules, power modules, memory modules, external clock modules, LCD modules Software system designed with C programming language, and follow the modular structure of the programming model, and has the RF card operation procedures, soft shutdown and automatic shutdown procedures, LCD display, serial Flash memory, an external clock, and other external device driver Procedures. The handset readers has the MF1 S50, S70 RF card reader function, real-time status display function, the system online update function and so
