SMART CARDS Using Embedded Technology

SMART CARDS Using Embedded Technology

ABSTRACT:

An embedded system is various type of computer system or computing device that performs a dedicated function and/or is designed for use with a specific embedded software application. Embedded systems may use a combination of ¡Read-only¡ as well as with ¡Read-Write¡ based operating system. But an embedded system is not usable as a commercially viable substitute for general-purpose computers or devices.

Imagine the power of a computer, the speed and security of electronic data, and the freedom to carry that information anywhere on earth. Imagine a computer so small it fits inside a plastic card like the credit card you carry in your wallet. Imagine the Smart Card.

The term Smart Card is loosely used to describe any card with a capability to relate information to a particular application such as magnetic stripe, optical, memory, and microprocessor cards. It is more precise, however to refer to memory and microprocessor cards as smart cards. Memory cards can store a variety of data, including financial, personal, and specialized information; but cannot process information.

Smart cards with a microprocessor look like standard plastic cards, but are equipped with an embedded Integrated Circuit (IC) chip. Microprocessor cards can store information, carry out local processing on the data stored, and perform complex calculations. These cards take the form of either “contact” cards which require a card reader or “contact less” cards which use radio frequency signals to operate.

This paper give us an idea of Embedded systems an its applications in day to day life. where as it gives an detail information about the Smart Cards which include how the Smart Cards work using an embedded technology its importance its security features an at last its various application in different field.
