Our country faces the aspect is more complex, must raise our country resident consumption level to develop the quick shopping, changes the people shopping way, causes the shopping way to enter a brand-new development model. The shopping is a important component which the city expends, the market operational guidance intellectualization, user-friendly is raises the public transportation service level the foundation, is also raises the operation efficiency, to improve the resident expense and the market management essential method, has manifested an urban modernization traffic control level, is China solves one of expense question important measures. The monolithic integrated circuit technology's fast development, specially the new liquid crystal, the U plate read-write module and miniature printer's being operational as well as each kind of programming language's development, has provided the full condition for the intelligent shopping's development. This article introduced that the intelligent information terminal development aspect, uses components and so on MSP430 monolithic integrated circuit, 240128 liquid crystals and PB375U plate module, uses Visual the C++ procedure programming, realizes between the monolithic integrated circuit, the U plate, the liquid crystal and the hot sensitive printer's function demonstration. Based on the market intelligence information terminal's appearance, provides the preferential benefit commodity, the dynamic real-time information service for the purchaser, reads functions and so on card recognition, scene inquiry, demonstration, self-service printing through the terminal, constructs one face each kind of journey comprehensive urban commodity information service system, provides each kind of commodity and the expense service accurately promptly, satisfies the society to the commodity information service demand, it will also have the huge function in present's commercial domain. Key words: Monolithic integrated circuit; Liquid crystal display; PB375 module; VC++
