Networked Driver Of Smart Card Reader And Industrial Controlling System

With the rapid development of chinese economy and the continuous pursuit ofconvenience life, the Smart Cards are more and more popular with most people.Forexample,the card by which we can consume something instead of cash in school,bankcard,mobile phone SIM card,all of them are smart card.and it is believable that everyone hasat least five such cards in hand.so the need of smart cards in the global market are huge.Thecritical part of the procedure of producing smart card is writing data into the smart card.thedata in the card inflect import personal information.so we need a steady,reliable smart cardreader writing data into card.The PC/SC specification is done by group consist of Mircrosoft and the worldwidefamous smart card manufacture.PC/SC is a standard set of APIs base on Microsoft platform,itprovider a integrated environment include personal computer and smart card.now windows isthe only platform supporting PC/SC so far,PC/SC gradually accepted by developer because ofthe influence of Microsoft corporation.PC/SC standard is upon the industrial standard ofISO-7816and standard of EMV.It do more work at underlying device interface and the API ofdevice-independence.The main advantage of PC/SC is developer do not need to take account of the detail ofthe connection between smart card and personal computer,such as connected by network orserial and any application that supporting PC/SC can work with any smart card readerfollowing PC/SC standard without any change.HDPS200machine is mainly used to download cos to smart card.Usually it connect120smart card readers,these readers is controlled by a computer. HDPS200can download cos to120smart cards each time. There are kinds of connections between computer and smart cardreader,such as by network,serial,USB.The connection of serial has a main disadvantage that isit work too slow,this will decrease the output of HDPS200in an hour.The connection of USBis not stable,which often appears the soft disconnection.while the connection of network hasno above two problems,and the connection is simple.Networked smart card reader driver and the HDPS200system has effective solutions tofix problems above.the connection between computer and smart card is by network with necessary software and hardware.The design of driver simplify the work of developing upperapplication.
