A smart card is any pocket-sized card with embedded integrated circuits which can process data. A smart card is a plastic card about the size of a credit card, with an embedded microchip that can be loaded with data, used for telephone calling, electronic cash payments, and other applications, and then periodically refreshed for additional use.
Smart cards can be used for identification, authentication, and data storage. These cards provide a means of effecting business transactions in a flexible, secure, standard way with minimal human intervention. Smart cards are also known as chip card or integrated circuit card. These can provide strong authentication to computers, laptops, and data with encryption.
Smart card writers are used as a communications medium between the smart card and a host. Since the chips in the financial cards are the same as those used for mobile phone cards, just programmed differently and embedded in a different shaped piece. Cards Writers are used in a wide variety of application and are becoming more popular. Card readers and writers are suitable for a wide range of uses.
Smart Card writers are also known as card programmers or card acceptance device. The term 'writer' is generally used to describe a unit that interfaces with a PC for the majority of its processing requirements.
The card writers provide a path for your application to send and receive commands from the card. There are many types of writers available, such as serial, PC Card, and standard keyboard models.
When the smart card and the card writer come into contact with the computer, 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.
