An Android Library to read info from NFC enabled cards
Inspired from EMV-NFC-Paycard-Enrollment and Credit-Card-NFC-Reader
Add this to your project's build.gradle
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}And include the dependency in your module's build.gradle
dependencies {
implementation 'com.github.vickyramachandra:nfc-card-reader:1.0.0'
}Make sure to handle if the device has NFC capabilities and it is enabled. In the Activity
public class MainActivity extends AppCompatActivity {
private NFCCardManager nfcCardManager;
private NFCCardReader nfcCardReader;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
nfcCardManager = new NFCCardManager(this);
nfcCardReader = new NFCCardReader();
}
@Override
protected void onResume() {
super.onResume();
nfcCardManager.enableDispatch();
}
@Override
protected void onPause() {
super.onPause();
nfcCardManager.disableDispatch();
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
// When the card is brought closer to the device, a new intent with TAG info is dispatched
Tag tag = intent.getParcelableExtra(NfcAdapter.EXTRA_TAG);
nfcCardReader.setTag(tag); // set the tag
NFCCardResponse cardResponse = nfcCardReader.readCard(); // read the card data
if (cardResponse != null && cardResponse.getEmvCard() != null) {
// use card data such as cardNumber, expire date etc
}
