Research On Multi-Function MINI Business Hall Terminal

Along with the rapid development of communication technology in China, especially the integration of communication technology and computer technology, the communication technology has been changing with each passing day, a new information era is coming to us. Now the general trend of communication technology is to personalized, digital, broadband, integration and intelligent, and it is targeted to communication technology providing for people an all-round, convenient and efficient service. But at present, the communication technology in our country is still not perfect, for some rural and remote areas, due to its broadband coverage is not wide, with net the bank at the township level set little dots, agency renewal difficult conditions, mobile phone card, charge still very inconvenient, all of the above to some extent not only affected the development of rural communication services lag, but also to people’s work and life caused inconvenience. Confronting the imbalance of business needs and development of communication technology, MINI electronic business hall enter the market with its powerful advantage.MINI business hall terminal is based on electronic business channel for the portable terminal, it access based platform through wire mode or wireless mode, supporting checking and payment as well as2G,3G card business in city, rural or remote areas and other outlets for telephone, cooperating with the existing electronic channels, to achieve seamless coverage of all channels.Under the above circumstance, this topic is to research a portable terminal of multi port with multi-function, through the hardware design and software development, to achieve business inquiries and handling, supporting multi-function wireless payment and billing print. On the one hand, it is a convenience for the masses especially for older users, no foot out of the village can apply the nearest business instead of the business hall queuing, it truly does the service to people side; on the other hand, through the terminal can expand the business scope and achieve a variety of payment business, it will solve the present existing problem such as the independent and dispersed channels of payment has not meet the payment time and money saving and centralized payment needs. This terminal through the wireless communication network operation support the magnetic stripe card reading, contact type IC card reading and RF mifare IC card reading, can be connected with the power supply or battery power, and have voice function.The terminal system using embedded microprocessor LPC2220of PHILIPS company as the hardware core processor. The terminal is based on hardware design, to complete the design of software through the integrated development environment of IAR EWARM. The main research content includes:the modular design of the terminal hardware, the software design of the underlying drivers, and finally the realization of human-computer interaction applications. The terminal is mainly consisted of four parts:the core microprocessor of LPC2220, the wireless communication module to connect operation business platform, human-computer interface which includes LCD display, keyboard input module and the necessary to complete the wireless payment behavior peripherals including PSAM card security encryption module, magnetic stripe card module, IC card authentication module, RF non-contact IC card module composition, finally complete the agreed transaction process, to achieve business query and management.
