CardInsertionWaiterNonBlockingSpi (Keyple Plugin Java API - 2.2.0)

```
public interface CardInsertionWaiterNonBlockingSpi
```
This SPI is specifically designed for plugins that don't handle card insertion autonomously but requires an external active stimulation to detect card insertion without implementing a waiting mechanism.
When a plugin implements this SPI, the ReaderSpi.checkCardPresence() method will be called periodically by the service when a card insertion is expected.
The value returned by the getCardInsertionMonitoringSleepDuration() will be used as an argument to Thread.sleep(long) between two calls to ReaderSpi.checkCardPresence().
A typical example of readers conforming to this mode of operation are terminals embedding a slave RF communication module.

Since:

2.2.0
