POS无线数据传输终端的设计

Design of wireless POS data transfer module

在基于公用电话网(PSTN)的有线POS的基础上,设计了一个通过GSM网络来同银行主机系统建立连接的终端模块,这样的话原有POS机既可以以原来的方式工作,也可以接上本文设计的终端模块通过GSM网建立同银行主机的连接。

Designing a wireless data tranfer module in connection of POS machine trading with bank host computer by GSM network is based on PSTN network, in this way, the old POS machine can not only work in the original way, but also connect with bank host computer by hanging the wire POS data transfer module in wireless way by GSM network.
