Setup

  1. Open up android/app/src/main/AndroidManifest.xml
  • Add <uses-permission android:name="android.permission.NFC" />
  • Add
    <service
              android:name="studio.bb.rnlib.CardService"
              android:exported="true"
              android:permission="android.permission.BIND_NFC_SERVICE">
              <intent-filter>
                  <action android:name="android.nfc.cardemulation.action.HOST_APDU_SERVICE" />
              </intent-filter>
              <meta-data
                  android:name="android.nfc.cardemulation.host_apdu_service"
                  android:resource="@xml/aid_list" />

<host-apdu-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:description="@string/service_name"
    android:requireDeviceUnlock="false">
    <aid-group
        android:category="other"
        android:description="@string/card_title">
        <aid-filter android:name="F201808175" />

public class CardService extends HostApduService {
 
private static final String TAG = "CardService";
