Interface WaitForCardInsertionBlocking

All Superinterfaces:

ObservableReader, ObservableReaderNotifier, Reader

public interface WaitForCardInsertionBlocking
extends ObservableReaderNotifier

Interface to be implemented by readers that are autonomous in the management of waiting for the insertion of a card and that provide a method to wait for it indefinitely.

A typical example of readers conforming to this mode of operation are PC/SC type readers capable of performing RF polling without waiting for a command from the application.

Method Detail

waitForCardPresent

boolean waitForCardPresent()

Waits for a card. Returns true if a card is detected, false it was interrupted or if the reader is no longer able to detect a card.

This method must be implemented by the plugin's reader class when it implements the WaitForCardInsertionBlocking interface.

Returns false if no card is detected.

Returns:

presence status

Throws:

KeypleReaderIOException - if the communication with the reader or the card has failed (disconnection)

stopWaitForCard

void stopWaitForCard()

Interrupts the waiting of a card
