Whereafter , the forecast about the trend of the contactless 1c cards - contactless cpu cards is given , and the method to solve the power supply problem for radio frequency cpu cards is analyzed 然后预测了非接触式ic卡的发展方向? ?非接触式cpu卡技术,并分析了解决射频cpu卡能量供给的方法。
The gas station management system mainly realize the distribution of cpu card , the input , sale and storage of gas station ' s oil business , and send the business affair to management center ; management center system mainly realize the cpu card ' s fabrication , publish , and gather the gas station ' s data , so as to find out the gas station ' s situation and make scientific decision in time 加油站管理系统主要实现cpu卡的销售以及油品的进、销、存等各种业务管理,并将每天的经营情况上传给管理中心;管理中心系统主要实现cpu卡的制作、发行,并对其下属加油站上传来的数据进行汇总,以便及时了解情况,做出科学决策。
These information - exchanging technologies mainly include the pos handset integrating barcode scanning , cpu card ' s storing and encrypting , double - card interlocking , the pos handset integrating modem and flashrom storing . this system integrates these information - exchanging technologies to gather , transmit and query information about civil explosive products " management expediently , swiftly and exactly . this system can lock responsibility for the civil explosive products in every their lifecycle and help supervising civil explosive products legally , strictly , exactly , syllabify and integrally 系统地研究了民爆产品管理系统中的信息交互技术,主要包括便携式pos集成条形码扫描采集信息、 cpu卡存储加密、 cpu卡双卡锁定、便携式pos集成modem传输数据、 flashrom存储技术等信息交互技术,民爆产品管理系统集成了这些信息交互技术,能够满足信息采集方便快捷、信息上报及时迅速、信息查询方便准确等需求,能够对民爆产品在每一个环节锁定责任单位和责任人,能够对民爆产品进行"合法、严密、准确、清晰、完整"地管理。
To realize this purpose , we develop a set of computer management system - the chain gas station cpu card management system . aim to improve the gas station ' s management level , this system uses the cpu card as its core , fully express cup card ' s specialty - high security , use cpu card to replace the handwork charge work 连锁加油站cpu卡管理系统就是为了适应这个目的而开发的一套计算机管理系统,该系统以cpu卡为核心,充分发挥cpu卡安全性高、保密性强的特点,用cpu卡代替手工收费,以提高加油站的管理水平。
A CPU card is a printed circuit board (PCB) that contains the central processing unit (CPU) of a computer. CPU cards are specified by CPU clock frequency and bus type as well as other features and applications built in to the card.
