Design and Implementation of Wireless Invoice Intelligent Terminal Based on ARM

In this paper, in order to solve the complexity and limitations of the current invoice issued, it designs and implements a wireless invoice intelligent terminal based on ARM [1]. The terminal is based on ARM embedded platform and the hardware part of the terminal is composed of main control module, memory module, LED liquid crystal display module and GPRS communication module. The software part of the terminal mainly includes the bottom driver design of Win CE system, the design of application software interface and the design of GPRS dial-up program. The invoice can be printed conveniently by using the wireless data interaction between software and tax administration information system. The system has been tested, which has the advantages of stable operation, friendly interface, convenient operation, low cost and easy popularization.
