UPOS WIP

Historical Background

UnifiedPOS was initiated by a consortium of retailers, and is led by the National Retail Federation. Beginning with release 1.5, both OPOS and JavaPOS have delegated ownership of language- and operating system-independent POS device interfaces to UnifiedPOS. OPOS then maps these interfaces to COM within Windows, and JavaPOS maps them to Java.
