<GrabbaMagstripeProtocol> Protocol Reference

Description

Interface for receiving magstripe reader events.

Objects which implement this protocol may receive callbacks when these events occur, via delegation from a GrabbaMagstripeListener object.

Note that this protocol need not be directly implemented; it may be simpler to subclass GrabbaMagstripeListener and thereby receive the events directly.

Thread safety: This interface is intended to be thread-safe; any classes deriving from it should ensure that the relevant methods are callable from any thread.
