摘要
介绍如何利用EM Microelectronic公司的射频卡读写基站芯片EM4094和Arasan公司的SDIO接口芯片AC2200来构建一种基于通用接口SDIO的即插即用型的RFID读写器,它可以在支持SDIO接口的掌上电脑或智能手机上使用,实现对13.56 MHz(ISO15693,ISO14443A/B/C等多种协议)RFID电子标签的读写,插拔方便,尺寸较小,可利用依托设备取电。这种方案为具有SDIO接口的智能终端提供了一种性能价格比很高的射频识别功能的扩展,从而使RFID在各行业的应用更加广泛和灵活。
How to use EM Microelectronic radio base station chip card readers EM4094 and Arasan＇s SDIO interface chip AC2200 to build a common interface based on the SDIO plug - and - play type of RFID readers is introduced. It can be used in the handheld computer or smartphone support SDIO interface, to achieve the 13.56 MHz （ISO15693, ISO14443A/B/C and other agreements） RFID electronic tags to read and write,swapping convenience of a smaller size,can rely on equipment from power. Such programm for SDIO interface with the smart terminal provides a very high price- performance RFID expansion, thus application of FRID in each fields is broader and more flexible.
