## EMV NFC Paycard Enrollment  [](https://coveralls.io/github/devnied/EMV-NFC-Paycard-Enrollment?branch=master) [](https://maven-badges.herokuapp.com/maven-central/com.github.devnied.emvnfccard/library) [](http://www.apache.org/licenses/LICENSE-2.0.html)
### 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](https://github.com/devnied/EMV-NFC-Paycard-Enrollment/blob/master/sample-pcsc/src/main/java/com/github/devnied/emvpcsccard/PcscProvider.java)).
```java
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.
```java
// 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](https://developer.android.com/reference/android/nfc/tech/IsoDep) class:
```java
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;
}
}
```
