Smart Cards In Wireless

The smart card is one of the latest additions to the world of information technology (IT). The size of a credit card, it has an embedded silicon chip that enables it to store data and communicate via a reader with a workstation or network. The chip also contains advanced security features that protect the card’s data.


Smart cards come in two varieties: microprocessor and memory. Memory cards simply store data and can be viewed as small floppy disks with optional security. Memory cards depend on the security of a card reader for their processing. A microprocessor card can add, delete, and manipulate information in its memory on the card. It is like a miniature computer with an input and output port, operating system, and hard disk with built-in security features.
