Debit vs credit vs prepaid card: what is the difference?

#Whose money are you spending with each card?

This is the core difference. A debit card takes money straight from your current (checking) account. A credit card lets you spend the card issuer's money up to a credit limit, and you repay later, with interest if you do not clear the balance. A prepaid card holds money you loaded in advance, so you can spend only what is on it. All three usually run through the same card networks and terminals, as described in how card payments work.

#Which card protects you best against fraud?

In the US, the law gives credit cards the simplest protection. Under Regulation Z, a cardholder's liability for unauthorised use of a credit card cannot exceed the lesser of $50 or the amount obtained before the issuer is notified⁠^[2]. Debit cards fall under Regulation E, where liability depends on timing: up to $50 if you tell your bank within two business days of learning of the loss or theft, and up to $500 if you tell it later⁠^[1]. If you do not report unauthorised transfers within 60 days of your statement, you can be liable for later transfers that timely reporting would have stopped⁠^[1].

There is also a practical difference. When a criminal uses your debit card, the money comes out of your own account, so you may be short of it until the bank sorts the problem out. With a credit card, the charge sits on a bill, and you do not have to pay the disputed part while it is investigated⁠^[5].

#How do disputes work on each card?

For credit cards, you must send a written billing-error notice within 60 days after the statement showing the error was sent; the issuer must acknowledge it within 30 days and resolve it within two complete billing cycles, and no later than 90 days⁠^[5]. While it is investigated, you do not have to pay the disputed portion⁠^[5]. The CFPB adds that you can dispute a charge even after paying it⁠^[8]. Card schemes also offer a chargeback process that your issuer uses to pull money back from the merchant.

#What should you know about prepaid cards?

Prepaid cards suit people who want to limit spending or who do not have a bank account. In the US, the CFPB's prepaid rule took effect on 1 April 2019; it requires clear upfront fee disclosures and gives prepaid account holders protections in case of errors, loss or theft⁠^[3]. Money on a prepaid card may be FDIC-insured through the bank that holds it, but only if the card is eligible, you register it and other requirements are met; coverage is up to $250,000, subject to your other deposits at the same bank⁠^[6].

Deposit insurance protects you if the bank fails. The FDIC notes it does not cover events such as losing the card or someone else gaining access to the funds⁠^[6]. For those situations you rely on the prepaid rule and your card agreement. For more on insurance, see how deposit insurance works.

#Does the shop pay different fees for each card?

Often yes, though it rarely changes what you pay at the till. In the EU, interchange on consumer debit cards is capped at 0.2% and on consumer credit cards at 0.3%⁠^[7]. In the US, debit interchange from large issuers is capped⁠^[9], while credit interchange is not capped by that rule. See interchange fees explained for the full story.

#So which card is right for which situation?

There is no single answer, and this page does not recommend any product. A debit card keeps spending tied to money you have. A credit card adds stronger fraud and dispute protections in the US but is a loan that must be repaid. A prepaid card caps spending at what you load and has its own protections.
