#Lenovo smart card reader drivers

When just using the drivers for each reader manufacturer there is no connection the functions of the card. The problem with the PC/SC method is that it does not support all of the reader functions offered by each manufacturer such as LED control and card latching/locking. This standard is supported by all major operating systems. The development of PC applications for readers has been simplified by the Personal Computer/Smart Card (PC/SC) standard. Allow ISO Commands to be sent to cards using a simplified or shortcut format (As in the CardLogix WinplexВ® API).Allow ISO Commands to be passed to cards using standard ISO format.Proprietary Commands for specific readers and cards.The following are some of the function calls provided for transporting APDUs and their functions:

Some APIs give the software designer the ability to select readers from multiple vendors. This is especially important if you have both memory and microprocessor cards that can are used in the same system. For ISO7816 processor cards the PC/SC interface is often employed, but it has limitations. Many smart card readers have specific drivers/APIs for memory cards. They are typically in some form of C, C++ or C # and will have the header files included. Most terminal SDKs come with a customized API for that platform. These layers of software can enable effective application communication with smart cards and readers from more than one manufacturer. The reader communicates with the card where the response to the request takes place.ДЇrom a technical perspective, the key is the APIs that are chosen. These commands, called APDUs (Application Protocol Data Units) can be executed at a very low level, or they can be scripted into APIs which enable the user to send commands from an application to a reader. Reader & Terminal to Card CommunicationДЄll cards and readers that follow ISO 7816-3 standards have a standardized set of commands that enable communication for CPU cards. These readers support magnetic stripe-contact and contactless read operations all in one device. Some readers support more than one type of card such as the tri mode insert readers from MagTek.

These methods include RS232 serial ports, USB ports, PCMCIA slots, floppy disk slots, parallel ports, infrared IRDA ports and keyboards and keyboard wedge readers. InterfaceДЄ contact reader is primarily defined by the method of it's interface to a PC. The dominant protocol under the ISO 14443 is MIFARE, followed by the EMV standards. Many contactless readers are designed specifically for Payment, Physical Access Control and Transportation applications. This type of reader works with a radio frequency that communicates when the card comes close to the reader. This interface enables larger data transport without the overhead of anti-collision and wireless breakdown issues that are a result from the card moving in and out of the reader antenna range. The typical PTS Protocol Type Selection (ISO7816-3) negotiated speed can be up to 115 kilo baud. This communication has the advantage of direct coupling to the reader and is considered more secure. The card-to-reader communications is often ISO 7816 T=0 only. This is the most common reader type for applications such as ID and Stored Value. This type of reader requires a physical connection to the cards, made by inserting the card into the reader.
