Step-by-step explanation:
Plastic money, such as debit cards, credit cards, and smart cards, are different ways to transfer money when making a purchase. A debit card allows you to transfer money directly from your bank account to the seller, while a credit card is a short-term loan from the credit card company to you. With a smart card, you can store a certain value of money on the card and use it to make purchases.
