Overview

Unified Point of Service 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 and a set of retail device behaviors sufficient to support a range of POS solutions.

POS for .NET is a class library that is part of Microsoft Windows Embedded for Point of Service. The class library provides .NET applications with interface for communicating with Point of Service peripheral devices, such as bar code scanners, magnetic card readers, receipt printers, and so on. In addition, POS for .NET includes a set of programming interfaces and base classes for vendors of POS peripheral devices.

Currently, 36 different point-of-service peripheral types are supported by the standard. Developed by a joint team of retailer and industry technical experts UnifiedPOS provides a consistent and exact framework for programming point of sales devices that is platform independent and vendor neutral.
