摘要
由于现行的POS机的系统界面简陋,软件资源匮乏,不利于POS机的功能扩展。刷卡器阅读芯片是POS机主要功能的承担者,对其Android驱动程序的研究,有助于POS机在Android平台上的发展。MagTek刷卡器阅读芯片21006450应用广泛,对于它的研究将有助于刷卡器阅读芯片驱动程序在实际中的应用。这里所研究的Android系统架构、芯片工作原理及接口调用是刷卡器阅读芯片驱动程序设计的理论基础,对驱动程序的实现做指导。
As the interface of available POS is simple and crude, and its software resource is lack, it is infaust to the func-tion expansion of the POS system. The POS reading chip undertake the main function of POS system, so the research of Android driver is very helpful for the development of POS system in Android environment. The reading chip 21006450 for MagTek POS system is widely used, so the research of it is benefit for the practical application of the driver for POS reading chip. The An- droid system architecture, working principle of the chip and interface calling researched in this paper are the theoretical basis of designing the POS reading chip driver.
