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.
