射频卡读写模块的资料，值得学习，发出来与大家共享。采用PHILIPS 公司的非接触技术设计的微型嵌入式非接触式IC卡读写模块。内嵌MF RC500射频基站，用户不必关心射频基站复杂的控制方法，只需要简单地通过选定的UART 或IIC 接口发送命令就可以对卡片进行所有的操作。该读卡模块是专门针对Mifare One读卡器设计的，带有默认自动寻卡功能。采用YW-201模块，用户可以在最短的时间内开发出符合自己需求的稳定的射频卡系统。-RF card reader module of the information, it is worth learning, the issue of sharing with everyone. PHILIPS companies using non-contact technical design of the micro-embedded non-contact IC card reader module. MF RC500 embedded RF base stations, base station radio frequency users do not have to care about the complexity of the control method, simply through the selected UART or IIC interface to send commands to the card can carry out all operations. The reader module is specifically designed Mifare One Card Reader with default automatic card feature. YW-201 modules used, the user can in the shortest time possible to develop in line with their needs stable RF card system.
