WHAT IS A SMARTCARD

V. Ryan 2002

 

A smartcard can be compared in size to a credit card. The common credit card differs in one important way - it has a magnetic strip. The smartcard is more sophisticated, instead of a magnetic strip to store the owner information it has an integrated circuit (known also as an IC or chip). This gives the smartcard a number of advantages as an integrated circuit can store much more information and  it is more secure. Magnetic strip cards can be manufactured relatively easily given simple equipment. On the other hand smartcards require much more sophisticated equipment to produce.

   

THE PARTS OF A SMARTCARD

 

An  interesting use of smartcard technology is seen in control technology. The smartcard can be programmed and then used to react to sensors and control devices such as motors, lights and buzzers. When the smartcard has been programmed it can be stored until needed or transported easily to a location anywhere in the world and then used. The programming and use of smartcards is covered in the following sections. The most important part of the smartcard is the integrated circuit which stores the program.
