Smart Card is a term used to describe several different types of card. Usually it refers to a credit-card sized card which contains a chip or magnetic strip which, when used with certain hardware, can enable you to do things like debit a purchase from your account, confirm your ID to a security device, or log you on to an NT workstation. They work because of the chip or magnetic strip they contain. These are programmable, that is they can be made to hold data which can be changed by certain hardware. Do you have a specific card you would like to know about?
