Step-by-step explanation:
A smart card is a plastic card that has a microchip loaded with identifying data. It is a type of plastic money, along with debit cards and credit cards, which are used for making purchases. When you make a purchase with a credit card, the credit card company immediately transfers money from its checking account to the seller, and at the end of the month, the credit card company sends you a bill for what you have charged that month. With a smart card, you can store a certain value of money on the card and then use it to make purchases.
