:::::notice{note}

:::::

## Code Samples

### Java 

You need to set up an `ECLCardReaderCancelRetrieveCardDataListener` to handle callbacks during the on-demand cancel card read operation.

```java
private ECLCardReaderInterface _cardReaderInterface;

// finding available card reader and initilizaing _cardReaderInterface
...

public void _cancelCardDataRetrieval()
{
 _cardReaderInterface.cancelRetrieveCardData(new ECLCardReaderCancelRetrieveCardDataListener()
 {
 @Override
 public void cardReaderCancelRetrieveCardDataDidSucceed(ECLCardReaderInterface cardReader)
 {
 //handle successful cancel operation
 }

 @Override
 public void cardReaderCancelRetrieveCardDataDidFail(ECLCardReaderInterface cardReader, final ECCError eccError)
 {
 //handle failed cancel operation
 }
 });
}
```

### Objective-C 

You need to set up a delegate to implement `ECLCardReaderCancelRetrieveCardDataDelegate` and pass it to `cancelRetrieveCardData` function of card reader protocol. 

```objc
[cardReader cancelRetrieveCardData:delegate];

...

+ (void)cardReaderCancelRetrieveCardDataDidSucceed:(id<ECLCardReaderProtocol>)cardReader {
 //handle successful cancel operation
}

+ (void)cardReaderCancelRetrieveCardDataDidFail:(id<ECLCardReaderProtocol>)cardReader error:(NSError *)error {
 //handle failed cancel operation
}
```
