EMV NFC Paycard Enrollment

Description

Java library used to read and extract public data from NFC EMV credit cards.

Android sample app available on Play store.

Getting started

First you need to create a custom Provider to exchange APDU with an NFC EMV credit card (sample here).

public class YourProvider implements IProvider {

  @Override
  public byte[] transceive(final byte[] pCommand) {
	 // implement this
  }

  @Override
  public byte[] getAt() {
     // implement this to get card ATR (Answer To Reset) or ATS (Answer To Select)
  }

}

After that, create an instance of a parser and read the card.

// Create provider
IProvider provider = new YourProvider();
// Define config
Config config = EmvTemplate.Config()
		.setContactLess(true) // Enable contact less reading (default: true)
		.setReadAllAids(true) // Read all aids in card (default: true)
		.setReadTransactions(true) // Read all transactions (default: true)
		.setReadCplc(false) // Read and extract CPCLC data (default: false)
		.setRemoveDefaultParsers(false) // Remove default parsers for GeldKarte and EmvCard (default: false)
		.setReadAt(true) // Read and extract ATR/ATS and description
		; 
// Create Parser
EmvTemplate parser = EmvTemplate.Builder() //
		.setProvider(provider) // Define provider
		.setConfig(config) // Define config
		//.setTerminal(terminal) (optional) you can define a custom terminal implementation to create APDU
		.build();
		
// Read card
EMVCard card = parser.readEmvCard();

card object contains all data read (Aid, card number, expiration date, card type, transactions history)

Android usage

For android, you can create a provider with IsoDep class:

public class Provider implements IProvider {

	private IsoDep mTagCom;

	@Override
	public byte[] transceive(final byte[] pCommand) throws CommunicationException {
		
		byte[] response;
		try {
			// send command to emv card
			response = mTagCom.transceive(pCommand);
		} catch (IOException e) {
			throw new CommunicationException(e.getMessage());
		}

		return response;
	}

	@Override
	public byte[] getAt() {
        // For NFC-A
		return mTagCom.getHistoricalBytes();
		// For NFC-B
        // return mTagCom.getHiLayerResponse();
	}


	public void setmTagCom(final IsoDep mTagCom) {
		this.mTagCom = mTagCom;
	}

}
