What is a debit card? How it works and your protections

A debit card lets you pay with money that is already in your account. When you use it, the amount comes out of your balance, usually within a day or two.

Debit, credit and prepaid

  1. Debit card: spends money from your own account.
  2. Credit card: spends money you borrow and pay back later.
  3. Prepaid card: spends money you load onto the card first.

Paying in shops and online

Debit cards work in shops, online and abroad wherever the card network (such as Visa or Mastercard) is accepted. In the UK, a single contactless payment can be up to £100; above that you insert the card and enter your PIN.

Your protection

If something you paid for by debit card doesn't arrive or isn't as described, you can ask your card provider for a chargeback. Section 75 protection, which covers some purchases between £100 and £30,000, applies to credit cards, not debit cards.
