How to use

val cardReader = CardReader.newInstance()
val cardReaderObservable = CardReaderObservable.newInstance(cardReader)

cardReaderObservable.event.collect { event: CardReaderEvent ->
    // CardReaderEvent.ReadyToScan
    // CardReaderEvent.StartReading
    // CardReaderEvent.CardLost
    // CardReaderEvent.NFCDisabled
    // CardReaderEvent.NFCNotSupported
    // CardReaderEvent.Error(Throwable)
    // CardReaderEvent.Success(CardData)
}

When NFC is disabled

cardReader.openNfcSettings(Context)

CardData

• aids List of card application identifiers
• types List of card types
• state UNKNOWN, ACTIVE, LOCKED
• expireDate Card expiration date as Date object

Under the hood

This library is using com.github.devnied.emvnfccard to read and parse the card data from the nfc chip.
