UnifiedPOS

UnifiedPOS is the acronym for Unified Point of Service and version 1.14 is the current standard. It is an architectural specification for application interfaces to point-of-service devices that are used in the retail environment. This standard, which has been in existence for several years, is both operating system-independent and language neutral and defines:     
  • An architecture for application interface to retail devices.
  • A set of retail device behaviors sufficient to support a range of POS solutions.
Currently, 36 different point-of-service peripheral types are supported by the standard. Platform dependent implementations are contained in specification appendices and are available for Java, and Microsoft OPOS and .NET.  Developed by a joint team of retailer and industry technical experts following published policies and procedures, UnifiedPOS provides a consistent and exact framework for programming point of sales devices that is platform independent and vendor neutral.
