Interface CardRemovalWaiterBlockingSpi

public interface CardRemovalWaiterBlockingSpi

This SPI is specifically designed for plugins that handle card removal synchronously. The plugin waits autonomously and indefinitely for the removal of a card by implementing a waiting mechanism.

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.

Since:

2.2.0
