![]() ![]() The options in terminal choices are just as varied. Most units have their own operating systems and development tools. They typically support other functions such as magnetic-stripe reading, modem functions and transaction printing. An extensive price and performance difference exists between an industrial strenth reader that supports a wide variaty of card protacols and the performance difference and the less expensive 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.in smart card reader.Īnother difference in reader types is on-board intellegence and capacities. However, some computer systems already come equipped with a built-in smart card reader. Readers come in many forms, factors and capabilities. The easiest way to describe a reader is by the method of its interface to a PC. Smart card readers are available that interface to RS232 serial ports, USB ports, PCMCIA slots, floppy disk slots, parallel ports, infrared IRDA ports and keyboards and keyboard wedge readers. Card readers are used to read data from – and write data to – the smart card. Readers can easily be integrated into a PC utilizing Windows 98/Me, 2000, or XP platforms. ISO command classes for communicating with 7816 protocol. Classes for communicating with the reader. Classes for converting data to a manufacturer-specific format.An application for testing and using the cards for an intended and specific purpose. The following classes are used for communicating with the 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. ![]() ![]() The reader provides a path for your application to send and receive commands from the card. There are many types of readers available, such as serial, PC Card, and standard keyboard models. Unfortunately, the ISO group was unable to provide a standard for communicating with the readers so there is no one-size-fits-all approach to smart card communication. When the smart card and the card reader come into contact, each identifies itself to the other by sending and receiving information. If the messages exchanged do not match, no further processing takes place. So, unlike ordinary bank cards, smart cards can defend themselves against unauthorized users and uses in innovative security measures. Smart cards are portable data cards that must communicate with another device to gain access to a display device or a network. Cards can be plugged into a reader, commonly referred to as a card terminal, or they can operate using radio frequencies (RF). Smart Card Readers are also known as card programmers (because they can write to a card), card terminals, card acceptance device (CAD) or an interface device (IFD). There is a slight difference between the card reader and the terminal. The term is generally used to describe a unit that interfaces with a PC for the majority of its processing requirements. In contrast, a terminal is a self-contained processing device. ![]()
