public abstract class AbstractWalletPinService
extends java.lang.Object
```
This class is mainly used to setup a Wallet PIN service which the MPA needs to implement. Depending on the first card profile provisioned into the device, underlying abstract methods may be called to manage the Wallet PIN use cases. The MPA shall implement this class to pass to WalletPinManager.bindAbstractWalletPinService(AbstractWalletPinService) method invocation.
