Introduction: The smart card is one of the latest additions to the world of information technology.
Similar in size to today's plastic payment card, the smart card has a microprocessor or memory chip embedded in it that, when coupled with a reader, has the processing power to serve many different applications.
As an access-control device, smart cards make personal and business data available only to the appropriate users. Another application provides users with the ability to make a purchase or exchange value.
Smart cards provide data portability, security and convenience.Smart cards today achieve much more than their original application of replacing cash and coins.
Smart cards grant access to secure areas, confirm a personís identity via biometrics, and retain large quantities of personal data (such as medical records.)
More important than these specific applications are the recent trends in how the smart cards are used Ė to facilitate the exchange of information between customer and proprietor, which is much broader than the concluding financial transaction.
Smart cards are plastic cards that contain a computer chip. Smart cards store larger amounts of information than magnetic stripe cards. They can also update this information and secure it at a higher level than a magnetic stripe.
