The interaction between users and smart cards include different components. They are SMART CARD Readers, Smart Card Interfaces, Primary Service Provider, Introducing Smart Cards to the System, Accessing a Smart Card, and Relation to Other Services.
Smart cards are becoming most advanced way for the world works. Combining microchip technology with credit card size, smart cards has become computing power directly into the consumer’s pocket. This is nothing but a CardTouch that comprises libraries of standard components
Smart Cards are used in different areas as a credit card, phone card, SIM card, MTN air time card, Super Card, Clicks, Edgars, Woolworths, Petrol Cards etc.
