| Resumen: | This document describes the Magnetic Stripe Device (MSD) as well as Chip Card
Device (CCD) classes 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 Magnetic Stripe devices and Chip Card devices the basic Device
Control structure is extended with various properties and methods specific to this
device which are described on the following pages. |
