Scope

This document describes the Check Reader/Scanner class based on the basic
architecture of J/XFS which is similar to the JavaPOS architecture. It is event
driven and asynchronous.
Three basic levels are defined in JavaPOS. For J/XFS this model is extended by a
communication layer, which provides device communication that allows distribution
of applications and devices within a network. So we have the following layers in
J/XFS:
• Application
• Device Control and Device Manager
• Device Communication
• Device Service
Application developers program against control objects and the Device Manager
which reside in the Device Control layer. This is the usual interface between
applications and J/XFS devices. Device Control objects access the Device Manager
to find an associated Device Service. Device Service objects provide the functionality
to access the real device (i.e. like a device driver).
During application startup the Device Manager is responsible for locating the
desired Device Service object and attaching this to the requesting Device Control
object. Location and/or routing information for the Device Manager reside in a
central repository.
To support Check Reader/Scanner devices the basic Device Control structure is
extended with various properties and methods specific to this device which are
described on the following pages.
