Embedded The The Javapos Platform Ejavapos The Research And Realization

With the improvement of the performance of the embedded systematic hardware and development of relevant software engineering, embedded use of POS more and more extensive, more enterprise and organization has joined the field of the application and service which are connected with POS already. Needn't pay more expenditure in order to make POS equipment increase the new function, Standard Unified POS norm which is made by national retail system alliance of U.S.A. (NRF-National Retail Federation) Branch retail terminal for technical standard association (ARTS-Association of Retail Technology Standards) is playing a more and more important role in POS solution because of its characteristic which is independent of operating system and programming language. To Unified POS system norm, there is extensive application on design and realization of terminal device in tax, retail business, bank, etc. There are two kinds of realization schemes mainly at present: OPOS is a kind of OLE2 based on Microsoft. X technology and POS norm of the operating system family (mainly on the basis of WIN32 system structure) are realized. JavaPOS is realized by POS norm based on JAVA PLATFORM of SUN. Among them JavaPOS no longer relies on the specific operating system, but construct on JAVA PLATFORM which is built in SUN Company, it is separate with the operating system to use, the same application can be and operating JVM because of different operating systems by any modification Run or realize on POS equipment that (JAVA virtual machine) that operates each other. In this way, great shortening the development period that POS uses, has safeguarded the expenses sparingly, therefore there are extremely extensive application prospects. This subject is in relevant taxes which meet the national standard normal to JavaPOS accuse of the module and foundation that analyse in detail of financial module, have consulted some technological characteristics of POS platform that has already realized, have realized a set of one that face embedded POSs, the ones that accord with international standard UnifiedPOS of POS equipment, open, safe platform of common software with independent intellectual property right, hereafter referred to as eJavaPOS. It collects POS system and operates and develops for the integrative platform, is formed by developing platform and operation platform.
