An extensive price and performance difference exists between an industrial strenth reader that supports a wide variaty of card protacols and the performance difference andВ theВ lessВ expensiveВ win-card reader that only works with microprocessor cards and performs all processing of the data in the PC. Some card readers come with advanced security features such as secure PIN entry, secure display and an integrated fingerprint scanners for the next-generation of multi-layer security and three-factor authentication.inВ smartВ cardВ reader.ДЄnotherВ differenceВ inВ readerВ typesВ isВ on-board intellegence andВ capacities. However,В someВ computerВ systemsВ alreadyВ comeВ equippedВ withВ aВ built-in smart card reader. ReadersВ comeВ inВ manyВ forms,В factorsВ andВ capabilities.В TheВ easiestВ wayВ toВ describeВ aВ readerВ isВ byВ theВ methodВ ofВ itsВ interfaceВ toВ aВ PC.В SmartВ cardВ readersВ areВ availableВ thatВ interfaceВ toВ RS232В serialВ ports,В USBВ ports,В PCMCIAВ slots,В floppyВ diskВ slots,В parallelВ ports,В infraredВ IRDAВ portsВ andВ keyboardsВ andВ keyboardВ wedgeВ readers.В CardВ readersВ areВ usedВ toВ readВ dataВ fromВ вЂ“В andВ writeВ dataВ toВ вЂ“В theВ smartВ card.В ReadersВ canВ easilyВ beВ integratedВ intoВ aВ PCВ utilizingВ WindowsВ 98/Me,В 2000,В orВ XPВ platforms. ISOВ commandВ classesВ forВ communicatingВ withВ 7816В protocol.В ClassesВ forВ communicatingВ withВ theВ reader.В ClassesВ forВ convertingВ dataВ toВ aВ manufacturer-specificВ format.AnВ applicationВ forВ testingВ andВ usingВ theВ cardsВ forВ anВ intendedВ andВ specificВ purpose. TheВ followingВ classesВ areВ usedВ forВ communicatingВ withВ theВ reader: The card will process the date and return it to the reader, which will then return the data to its originating source. Third, communication with a smart card is based on the APDU format. Second, the reader communicates with the card, acting as the intermediary before sending the date to the card.

Each manufacturer provides a different protocol for communication with the reader. TheВ readerВ providesВ aВ pathВ forВ yourВ applicationВ toВ sendВ andВ receiveВ commandsВ fromВ theВ card.В ThereВ areВ manyВ typesВ ofВ readersВ available,В suchВ asВ serial,В PCВ Card,В andВ standardВ keyboardВ models.В Unfortunately,В theВ ISOВ groupВ wasВ unableВ toВ provideВ a standardВ forВ communicatingВ withВ theВ readersВ soВ thereВ isВ noВ one-size-fits-all approach to smart card communication. WhenВ theВ smartВ cardВ andВ theВ cardВ readerВ comeВ intoВ contact,В eachВ identifiesВ itselfВ toВ theВ otherВ byВ sendingВ andВ receivingВ information.В IfВ theВ messagesВ exchangedВ doВ notВ match,В noВ furtherВ processingВ takesВ place.В So,В unlikeВ ordinaryВ bankВ cards,В smartВ cardsВ canВ defendВ themselvesВ againstВ unauthorizedВ usersВ andВ usesВ inВ innovativeВ securityВ measures. SmartВ cardsВ areВ portableВ dataВ cardsВ thatВ mustВ communicateВ withВ anotherВ deviceВ toВ gainВ accessВ toВ aВ displayВ deviceВ orВ aВ network.В CardsВ canВ beВ pluggedВ intoВ aВ reader,В commonlyВ referredВ toВ asВ aВ cardВ terminal,В orВ theyВ canВ operateВ usingВ radioВ frequenciesВ (RF). SmartВ CardВ ReadersВ areВ alsoВ knownВ asВ cardВ programmersВ (becauseВ theyВ canВ writeВ toВ aВ card),В cardВ terminals,В cardВ acceptanceВ deviceВ (CAD)В orВ anВ interfaceВ deviceВ (IFD).В ThereВ isВ aВ slightВ differenceВ betweenВ theВ cardВ readerВ andВ theВ terminal.В TheВ termВ isВ generallyВ usedВ toВ describeВ aВ unitВ thatВ interfacesВ withВ aВ PCВ forВ theВ majorityВ ofВ itsВ processingВ requirements.В InВ contrast,В aВ terminalВ isВ aВ self-containedВ processingВ device.
