| This topic comes from the combination of eJavaPOS and Fiscal Cash Register, mainly studying embedded development under platform of eJavaPOS. The most challenge of the embedded product is the transplantability of the system.eJavaPOS runs on the java virtual machine ,and completely inherits both transplantability and Cross-platform ,which are the advantages of Java.In addition ,the device manager specilizes ,configs and manages all of the devices of the system, only the migration of the device manager and under it will be needded when dealing with system migration,which doesn't affect the running of upper software.Thus it will be more easier to migrate the whole platform.The design of this project bases on the specification of Fiscal Cash Register and IC card and the requirement of user . The schema can meet not only the demand of tax control operation of present stage, but the development of Fiscal Cash Register in the future. The project designs and realizes the client machine in building, storing and transporting of data ,which insures the realization of the requirement working-out by State Administration of Taxation.eJavaPOS is an open and general platform facing to embedded POS and suitable to the specification of JavaPOS ,the standard of tax controlling and the financial standards of state.eJavaPOS provides a good solution for the problems of the transplantability ,dynamic loading ,safety and cross-platform of embedded POS system .it can support other 3rd party developing application easily,simplifies and standardizes the developing flow of POS application, and shorten developing cycle and the time of coming into the market of application system. UnifiedPOS is an international architectural specification for application interfaces to point-of -service devices that are used in the retail environment .it specifies all of POS device uniformly and is independent from operation system and language in the meanwhile. UnifiedPOS has two implement method at present:OPOS base on OLE and... |
