This library helps developer to read data from credit card: card number, expired date, card type.
Works only with cards that has paypass or paywave technology!

super.onNewIntent(intent);
if (mNfcAdapter != null && mNfcAdapter.isEnabled()) {
//this - interface for callbacks
//intent = intent :)
//mIntentFromCreate - boolean flag, for understanding if onNewIntent() was called from onCreate or not
mCardNfcAsyncTask = new CardNfcAsyncTask.Builder(this, intent, mIntentFromCreate)
.build();
}
}
That's pretty much all what you need to start the work!
This is the main callback for managing:
@Override
public void startNfcReadCard() {
//notify user that scannig start
}
@Override
public void cardIsReadyToRead() {
String card = mCardNfcAsyncTask.getCardNumber();
String expiredDate = mCardNfcAsyncTask.getCardExpireDate();
String cardType = mCardNfcAsyncTask.getCardType();
}
@Override
public void doNotMoveCardSoFast() {
//notify user do not move the card
}
@Override
public void unknownEmvCard() {
//notify user that current card has unnown nfc tag
}
@Override
public void cardWithLockedNfc() {
//notify user that current card has locked nfc tag
}
@Override
public void finishNfcReadCard() {
//notify user that scannig finished
}
