How Debit Cards Work

What Is a Debit Card?

A debit card is a payment card linked directly to your bank account. When you use it to pay for something, the money is immediately deducted from your account balance. It’s like having cash in your pocket but with the convenience of plastic.

How Do Debit Cards Work?

Here’s a simple step-by-step of what happens when you use your debit card:

1. Swipe, Insert, or Tap:
   You can swipe the card’s magnetic stripe, insert it into a chip reader, or tap it on a contactless terminal. If you’re shopping online, you’ll enter the card details manually.
2. Authentication:
   You’ll usually need to enter a Personal Identification Number (PIN) or sign a receipt to verify the transaction. For some contactless payments, skip this step for smaller amounts.
3. Authorization:
   The payment terminal or ATM communicates with your bank to check if you have enough money in your account to complete the transaction.
4. Transaction Complete:
   If your account has sufficient funds, the money is deducted right away, and the payment is approved. If not, the transaction will be declined unless you have overdraft protection.

Key Features of Debit Cards

• Immediate Access to Funds:
  Unlike credit cards, debit cards pull money directly from your bank account.
• ATM Withdrawals:
  You can use your debit card to withdraw cash from ATMs, often without fees if you use your bank’s network.
• No Debt Worries:
  Since you’re using your own money, there’s no risk of running up a credit card debt.
• Spending Control:
  Debit cards help you stick to a budget because you can only spend what you have in your account.
