本文主要是介绍商米-android-使用NFC读IC卡，身份证云解和IC卡同时兼容，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
商米介绍地址：https://www.sunmi.com/
商米是一个提供手持PDA的一个很好的解决方案厂商，
也有其他的一些桌面设备。
其中商米提供的软件服务中，比较特别的是 身份证云解功能。
此处重点说明一下，身份证云解功能。
以往市面上的身份证读卡功能，都是找公安申请身份证读卡器硬件模块。比较贵。
商米的身份证读卡，是利用商米的NFC功能，配合身份证云解功能来实现
单独实现身份证读卡，和单独实现NFC刷IC卡，在商米提供的SDK很容易能实现
但是同时实现兼容 读IC卡和身份证，现在的商米SDK 就兼容性做的很差。
这里主要说明一下同时兼容 读IC卡和身份证，
1、引用jar包：implementation ‘com.sunmi:SunmiEID-SDK:1.3.16’
2、主界面上，初始化NFC，NfcUtils
package com.smk.travelpda.common.nfc;import android.app.Activity;

NFC监听组件
package com.smk.travelpda.common.nfc;import android.nfc.Tag;/*** 自定义的NFC接口*/public interface NfcListener{/*** 用于扫到nfc后的后续操作*/void nfcReadHander(Tag tag);}

}
这个兼容身份证和IC读卡的关键点在于，不要使用SDK里面 EidSDK.startCheckCard();
1、EidSDK.init方法，
2、在EidSDK.init的成功回调函数中，获取NFC读卡的
EidReader eid = EidSDK.getEidReaderForNfc(3, new EidCardReadCall(this,EidHanderEo.Eid_READY_NFC));
3、初始化成EidReader ， 此时刷卡，在NFC读卡器检测到NFCB 的tag类型之后，再使用EidReader 去处理身份证读卡的功能 eid.nfcReadCard(tag); 此处会在第二部的回调函数中 得到读取身份证的结果。
