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;
import android.content.Context;
import android.nfc.NfcAdapter;
import android.nfc.Tag;
import android.util.Log;
import android.widget.Toast;import com.smk.travelpda.common.util.RString;/*** luoyang*/public class NfcUtils {private static final String TAG = "NfcUtils";private static NfcAdapter mNfcAdapter;private NfcUtils(){}private static NfcUtils nfcUtils = null;private static boolean isOpen = false;/*** 获取NFC的单例* @return NfcUtils*/public static NfcUtils getInstance(){if (nfcUtils == null){synchronized (NfcUtils.class){if (nfcUtils == null){nfcUtils = new NfcUtils();}}}return nfcUtils;}private  NfcListener nfcListener;public void setNfcListener(NfcListener listener){nfcListener = listener;}/*** 在onStart中检测是否支持nfc功能* @param context 当前页面上下文*/public void onStartNfcAdapter(Context context){//设备的NfcAdapter对象mNfcAdapter = NfcAdapter.getDefaultAdapter(context);}/*** 在onResume中开启nfc功能* @param activity*/public void onResumeNfcAdapter(final Activity activity){if(mNfcAdapter==null){//判断设备是否支持NFC功能RString.showDia(activity,"提醒","设备不支持NFC功能");return;}if (!mNfcAdapter.isEnabled()){//判断设备NFC功能是否打开RString.showDia(activity,"提醒","请到系统设置中打开NFC功能!");return;}if (!isOpen) {mNfcAdapter.enableReaderMode(activity, new NfcAdapter.ReaderCallback() {@Overridepublic void onTagDiscovered(final Tag tag) {if (nfcListener != null){(activity).runOnUiThread(new Runnable() {@Overridepublic void run() {nfcListener.nfcReadHander(tag);}});}}},(NfcAdapter.FLAG_READER_NFC_A |NfcAdapter.FLAG_READER_NFC_B |NfcAdapter.FLAG_READER_NFC_F |NfcAdapter.FLAG_READER_NFC_V |NfcAdapter.FLAG_READER_NFC_BARCODE ),null);isOpen = true;}}/*** 在onPause中关闭nfc功能* @param activity*/public void onPauseNfcAdapter(Activity activity){if(mNfcAdapter!=null && mNfcAdapter.isEnabled()){if (isOpen){mNfcAdapter.disableReaderMode(activity);}isOpen = false;}}}

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。
