Card reader 2

A smart card reader is an electronic device that reads smart cards and can be found in the following forms: (1) Some keyboards have a built-in card reader. (2) External devices and internal drive bay card reader devices exist for personal computers (PC). (3) Some laptop models contain a built-in smart card reader and/or utilize flash upgradeable firmware. External devices that can read a Personal identification number (PIN) or other information may also be connected to a keyboard (usually called "card readers with PIN pad"). This model works by supplying the integrated circuit on the smart card with electricity and communicating via protocols, thereby enabling the user to read and write to a fixed address on the card.
