Abstract

The invention discloses a software framework which is a framework suitable for application software of a POS (point of sale) terminal. The software framework comprises an application layer, an operating system layer and an application programming interface layer, wherein the operating system layer is used for providing an application programming interface function and feeding back the application programming interface function which is used for executing businesses of the POS terminal; the application programming interface layer is used for packaging the application programming interface functions fed back by different operating system layers again to obtain a unified application programming interface function, so that the application layer can develop application layer software codes with the same business function according to the unified application programming interface function, various POS terminals produced by different POS manufacturers can use the same application layer software code to execute the same business function, and the universality is improved. Further, all that is needed is to change the application layer software code once when the application layer software code is updated, then the updating efficiency is improved, and the cost is saved.

Description

technical field [0001] The present invention relates to the technical field of point-of-sale terminals, in particular to a software architecture suitable for running on point-of-sale terminals. Background technique [0002] POS (Point of sale, point of sale) terminal is a device that has communication functions and can complete information interaction. For example, a POS terminal can receive bank card information, send the bank card information to the terminal at the counter, and then use the The teller at the terminal sends instructions to the POS terminal to complete the financial transaction. [0003] In the existing technology, the OS (Operating System, operating system) used by the POS terminals produced by each POS manufacturer is developed by their own R&D personnel. Since the OS developed by different POS manufacturers for the same business is different, different POS manufacturers provide POS terminals with The API (Application Programming Interface, Application Pr...
