What will be an ideal response?
A smart card is a credit card-sized piece of plastic that has built-in computer circuitry and components-typically a processor, memory, and storage. Smart cards today store a relatively small amount of data (typically 64 KB or less) that can be used for payment or identification purposes. For example, a smart card can store a prepaid amount of digital cash, which can be used for purchases at a smart card-enabled vending machine or to pay transit fares-the amount of cash available on the card is reduced each time the card is used. Smart cards are also commonly used worldwide for national and student ID cards, credit and debit cards adhering to the global EMV standard to increase security and decrease fraudulent use, as discussed in the Chapter 9 Inside the Industry box, and access cards for facilities or computer networks. Although these applications have all used conventional magnetic stripe technology in the past, the processor integrated into a smart card
can perform computations-such as to authenticate the card, encrypt the data on the card to protect its integrity, and secure it against unauthorized access-and can allow data to be added to the card or modified on the card as needed.
