在工作中曾完成的一个NFC读卡器，
主要使用的ST公司的新推出的CR95HF芯片，做板测试已OK。
对于从事NFC开发的人员绝对是一种值得备用的资料。
（附件提供原理图，CR95HF编程手册，驱动CR95HF的C源代码，另包含有 对双接口芯片M24LR64的驱动）

CR95HF芯片有如下特点：
标准频率：13.56-MHz
支持多协议：ISO/IEC 14443 A and B，ISO/IEC 15693，ISO/IEC 18092
提供2种标准接口： SPI 和 UART 。
只需简单的7条指令：
(Work was done in a NFC reader, the main use of the ST' s new CR95HF chip board test has to do OK. Personnel engaged in the development of NFC is definitely a worthy alternative information. (Annex provides schematics, CR95HF programming manual, driver CR95HF the C source code, and the other contains the dual interface chip M24LR64 driver) CR95HF chip has the following characteristics: standard frequency :13.56-MHz multi-protocol support: ISO/IEC 14443 A and B, ISO/IEC 15693, ISO/IEC 18092 provides two standard interfaces: SPI and UART. 7 simple instructions:)
