If you regularly spend money on things like snacks, movies, or transportation, you might carry around a lot of cash. An alternative to a wallet full of dollar bills is a debit card. This is a plastic card that is linked to your checking account. You can use it to buy stuff or take cash out of an ATM.
Every time you use your debit card, the money is withdrawn directly from your checking account. You can link your debit card to apps like Venmo, Cash App, or PayPal to send or receive money to and from friends.
Credit cards can also be useful, but you need to be careful with them. When you use a credit card, you’re actually borrowing money from the bank. The bank doesn’t let you borrow that money for free.
At the end of each month, you need to pay back the amount of money you borrowed. If you can’t pay back the total amount, the bank will charge you interest on what you owe. They may also charge late fees.
Credit cards can be dangerous because of how the interest and fees add up. The amount of interest banks charge for credit cards changes yearly, but it can be as high as nearly 30 percent. This means that if you buy a $100 pair of jeans with your credit card and you don’t pay back the $100 by the end of the month, after a year those jeans can cost you more than $130.
