A smart card is a plastic card about the size of a credit card, with an embedded microchip that can be loaded with data, used for telephone calling, electronic cash payments, and other applications, and then periodically refreshed for additional use. Currently or soon, you may be able to use a smart card to:
> Dial a connection on a mobile telephone and be charged on a per-call basis
> Establish your identity when logging on to an Internet access provider or to an online bank
> Pay for parking at parking meters or to get on subways, trains, or buses
> Give hospitals or doctors personal data without filling out a form
> Make small purchases at electronic
> stores on the Web (a kind of cybercash)
> Buy gasoline at a gasoline station
