Smart Card technology
Internet technologies, through intranet and extranet applications, have proven themselves to be efficient and effective in streamlining existing processes from supply chain management to manufacturing logistics, from marketing to customer asset management, nd by creating new value chains and businesses. Nevertheless, these changes and benefits signal only an evolutionary shift in the way we do business. The Internet-enabled conomy resembles the conventional physical market in many aspects. Some of the new technologies and applications may even be unnecessary. American consumers, for xample, regard smart cards as a redundant payment mechanism when checks, credit cards and ATM cards do an adequate job for current needs. What is the use of smart ards? Do we really need them? Will they ever take off?
Today, the SIM card’s basic functionality in wireless communications is subscriber authentication and roaming. Although such features may be achieved via a centralized intelligent network (IN) solution or a smarter handset, there are several key benefits that ould not be realized without the use of a SIM card, which is external to a mobile handset. These benefits—enhanced security, improved logistics, and new marketing pportunities—are key factors for effectively differentiating wireless service offerings. This tutorial assumes a basic knowledge of the wireless communications industry and ill discuss the security benefits, logistical issues, marketing opportunities, and customer benefits associated with smart cards.
The smart card is one of the latest additions to the world of information technology (IT). he 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 tore 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 dd, 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 ecurity features.
