When you open a checking account, your bank typically furnishes you with a free ATM card that may be used to make cash withdrawals and deposits, transfer funds between accounts, and check account balances. Some ATM cards also function as debit cards, which may be used to make purchases both online and at retail establishments. Such cards have visible Visa, Mastercard, Discover, or American Express logos.

Debit cards can be used in place of credit cards, but there are some things to be aware of when using a debit card to pay for rental cars and hotel stays, where the bill totals can be calculated only after you return your car or check out of your room. These billers may place an authorization hold on your account, which can tie up your checking account's funds.

ATM Cards

Automated Teller Machine (ATM) cards are the simplest cards. They are offered by banks and some credit unions. These cards find use to withdraw cash and make basic banking transactions at ATMs located in many places. Most issuers will charge a user fee each time the card is used to withdraw funds.

Debit Cards

Debit cards, also known as check cards, do everything ATM cards do but can also be used for purchases anywhere credit cards are accepted, including retail stores and online sites. The funds from these transactions and taken directly from your checking account. The issuer of these cards will often charge a fee for the convenience of using the debit card instead of a paper check.

Credit Cards

Credit cards let you borrow—take a cash advance—from your credit card issuer. Funds do not come directly out of your checking account. There may be fees for taking cash advanced on your credit card. You will have a loan balance for any advance you take that you must pay off at a later date. It’s wise to pay off the entire balance every month in order to avoid hefty interest charges. For everyday spending, credit cards are safer than debit cards for the following reasons:

If somebody steals your debit card or obtains your card number, thieves can immediately drain your checking account, making it potentially difficult for you to pay bills.

Credit cards offer superior consumer protection against fraud by limiting your losses to $50, under federal law, for unauthorized charges. While most debit cards likewise protect against fraud and errors, federal law is not as generous with debit card loss limits.

But credit cards also have drawbacks. Chief among them: They may tempt you to spend beyond your means and end up with a pile of high-interest debt.

Prepaid Debit Cards

Prepaid debit cards are similar to standard debit cards, but instead of pulling funds from a checking account, you “load” funds into an account with the prepaid debit card issuer. This may be done either by setting up direct deposit, adding funds with an electronic transfer or an in-person deposit, or using a mobile check deposit. You can then spend from the card until you’ve used up the money you loaded.

It is relatively easy to qualify for prepaid cards, making them an attractive option for those who have experienced difficulty opening a bank account. On the downside, prepaid debit cards can be expensive, and they’re not as useful as fully functioning debit cards.
