支付使主机卡仿真工作 [英] Making Host Card Emulation work for payment
问题描述
我一直在使用计算器好几年了，一直寻找答案我的问题，甚至要求他们之前，但今天我坚持。
I've been using StackOverflow for years now, always finding answers to my questions before even asking them, but today I'm stuck.
当我正好有一个工作POS终端（的EMV芯片和放大器;针的那种），我想看看主机卡仿真。
As I happen to have a working POS terminal (the EMV Chip&Pin kind), I wanted to look into host card emulation.
该终端可以与特普的最新版本，所以我知道，终端是好的，我的N7与奇巧实际上可以支付（或者至少是终端做了一系列很好的冠冕堂皇的bleeps和bloops和平板电脑推出特普招生屏幕）。
所以，我读过说明书（S），并写了一堆线与看到的东西的客观到达我的 HostApduService 。
这部分的工作，我可以找到抽头放我的假证;缴纳平板电脑的设置
The terminal works with the latest version of Tapp, so I know that the terminal is good and that my N7 with Kitkat can actually do payment (or at least the terminal do a series of good sounding bleeps and bloops, and the tablet launch Tapp's enrollment screen).
So I've read the manual(s) and written a bunch of lines with the objective of seeing something arrive on my HostApduService.
It partially works as I can find my dummy "card" in the Tap&Pay settings of the tablet.
但支付部分不工作：只有两个从平板电脑的POS终端并没有什么高亢bleeps。我的 HostApduService 不叫。
But the "payment" part doesn't work: just two high-pitched bleeps from the POS terminal and nothing on the tablet. My HostApduService is not called.
我已经尝试了所有不同类型的艾滋病：以假乱真的和愚蠢的，短期和长期的，但没有任何工程
I've tried all kind of different AIDs: real ones and silly ones, short and long, but nothing works.
在使用特普，在LogCat中说：
When using Tapp, the LogCat says :

11-17 14:51:49.932: E/BrcmNfcNfa(3183): UICC[0x0] is not activated
和我的code时，LogCat中是：
And with my code, the LogCat is :
11-17 14:41:52.079: D/BrcmNfcJni(3183): RoutingManager::stackCallback: event=0x18
11-17 14:41:52.079: D/HostEmulationManager(3183): notifyHostEmulationActivated

11-17 14:41:53.340: E/BrcmNfcNfa(3183): UICC[0x0] is not activated
显然与我的code，操作系统不绑定HCE意图，我的服务。但是，为什么？
Obviously with my code, the OS doesn't bind the HCE intent to my service. But why?
您会发现我下面的清单：
You'll find below my manifest :
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="net.remolagi.hcetestbanque2"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="19"
android:targetSdkVersion="19" />
<uses-permission android:name="android.permission.NFC" />
<uses-feature
android:name="android.hardware.nfc.hce"
android:required="true" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="net.remolagi.hcetestbanque2.MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:name=".MyHCEService"
android:exported="true"
android:permission="android.permission.BIND_NFC_SERVICE" >
<intent-filter>
<action android:name="android.nfc.cardemulation.action.HOST_APDU_SERVICE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
<meta-data
android:name="android.nfc.cardemulation.host_apdu_service"
android:resource="@xml/apduservice" />
</service>
</application>
</manifest>
我apduservice.xml：
my apduservice.xml :
<?xml version="1.0" encoding="UTF-8"?>
<host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android"
android:description="@string/servicedesc"
android:requireDeviceUnlock="true"
android:apduServiceBanner="@drawable/payment_banner">
<aid-group android:description="@string/aiddescription"
android:category="payment">
<aid-filter android:name="A0000000031010"/>
</aid-group>
</host-apdu-service>
和良好的措施，服务（如你此刻看到的，它什么都不做，除了记录）：
And for good measure, the service (as you can see at the moment, it does nothing except Logging) :
package net.remolagi.hcetestbanque2;
import android.nfc.cardemulation.HostApduService;
import android.os.Bundle;
import android.util.Log;
public class MyHCEService extends HostApduService {
private static final String TAG = "MyHCEService";
@Override
public void onDeactivated(int arg0) {
Log.i(TAG, "OnDeactivated - arg0 : " + String.valueOf(arg0));
// TODO Auto-generated method stub
}
@Override
public byte[] processCommandApdu(byte[] arg0, Bundle arg1) {
Log.i(TAG, "Hooza ! processCommandApdu");
return arg0;
}
}
如果你有，为什么它不工作的想法，我会永远感激。现在，我很为难。
If you have ideas on why it doesn't work, I'll be forever grateful. For now, I'm stumped.

推荐答案
这将通过EMV终端被选择的第一个小程序是PPSE小程序，让您可以尝试也添加到您的AID的过滤器：
The first applet that will be selected by a EMV terminal is the PPSE applet, so you can try to add it also to your AID filters:
<aid-filter android:name="325041592E5359532E4444463031"/>
我不知道为什么你正在试图模仿支付与HCE，但这绝不会由Visa和万事达卡的批准，因为对EMV交易，你需要需要被存储在安全的环境中的加密密钥。在最好的情况下，HCE可用于无卡present交易。
I don't know why you are trying to emulate payment with HCE but this will never be approved by Visa and MasterCard since for EMV transaction you need a cryptographic keys that need to be stored in secure environment. In the best case the HCE can be used for card not present transactions.
