The three ways to pay with a credit card at checkout

Most payment terminals now accept three methods: swiping the magnetic stripe on the back of your card, inserting the chip into the slot, or tapping the card near the contactless reader. Which one works depends on what your card has and what the terminal supports. Chip and contactless are more secure than swiping, so terminals often prompt you to use those first if your card has them.

The terminal will usually tell you which method to use, either on screen or with a beep or light. If one method doesn't work, try another. You don't need to do anything special to your card — just follow the terminal's instructions.

Key Takeaways

  • Swiping pulls data from the magnetic stripe on the back of your card and is the oldest payment method, now less common at most retailers.
  • Inserting the chip into the slot is more secure than swiping because the chip creates a unique code for each transaction that can't be reused.
  • Tapping your card near the contactless symbol is the fastest method and works for most cards issued in the last five years.
  • The terminal will prompt you which method to use, and you should never hand your card to the cashier if a chip or contactless option is available.

Swiping the magnetic stripe

To swipe, hold your card with the magnetic stripe (the dark band on the back) facing the terminal. Insert the card into the slot on the side of the terminal and pull it through in one smooth motion, stripe-first. The terminal will read the data and either ask you to enter your PIN or sign, depending on the transaction amount and your card's settings.

Swiping is becoming rare at major retailers because it's less secure — the magnetic stripe data doesn't change from transaction to transaction, so a stolen card number can be used repeatedly. Gas stations, some small businesses, and older terminals still use swiping, but most stores have moved to chip or contactless.

Inserting the chip

To use the chip, locate the small metallic square on the front of your card. Insert the card into the slot on the terminal with the chip facing into the machine. Push the card in until it stops — you'll usually hear a beep. Leave the card in the terminal while it processes. Do not remove it until the screen tells you it's safe to do so, which typically takes five to ten seconds.

The chip creates a unique encrypted code for each transaction, so even if someone intercepts the data, they can't reuse it. This is why chip readers are more secure than magnetic stripe swiping. After the transaction processes, the terminal will prompt you for a PIN or signature, then tell you to remove your card.

Tapping for contactless payment

Contactless payment uses radio frequency to send your card information to the terminal without physical contact. Look for a curved wave symbol on the terminal or your card. Hold your card a few inches away from the reader and tap or hold it there for a second. The terminal will beep or show a checkmark when the payment goes through.

Contactless is the fastest method — the whole transaction takes two to three seconds. Most cards issued since 2020 have contactless capability, and nearly all modern terminals support it. You don't need a PIN for most contactless transactions under a certain amount (usually $25 to $100, depending on your bank and card type), though some terminals may ask for one anyway.

What to do if the terminal rejects your card

If one method doesn't work, try another. A chip reader might reject a card if the chip is dirty or damaged — try wiping the chip with a dry cloth and inserting it again. If the chip still doesn't work, ask the cashier if you can swipe instead. If swiping fails, the terminal may not support that method, or your card's magnetic stripe could be worn.

If none of the methods work, contact your bank to check whether your card is active and has no fraud blocks. Sometimes a terminal is simply broken or out of service. In that case, you can pay with a different card, use cash, or ask the store if they can process the payment manually.

Keeping your card safe during payment

Never hand your physical card to a cashier if the terminal is within reach. Always insert or tap your card yourself into the reader. If a cashier insists on taking your card out of sight, ask to use a different payment method or take your business elsewhere — this is a common setup for card skimming.

Check your card for damage before you use it. A cracked or bent chip, a peeling magnetic stripe, or visible wear can cause payment failures. If your card is damaged, contact your bank to order a replacement. Also watch the terminal screen during the transaction to make sure the amount is correct before you enter your PIN or sign.

Frequently Asked Questions

Do I need to remove my card right away after tapping?

No. You can leave your card near the terminal for a few seconds after tapping. The transaction completes in about one second, and the terminal will beep or show a checkmark when it's done. You can then remove your card and put it away.

What's the difference between contactless and chip?

Contactless uses radio waves and requires no physical contact with the terminal. Chip requires you to insert the card into a slot. Both are more secure than swiping. Contactless is faster, but chip is more widely supported at older terminals and some small businesses.

Can I swipe a card that has a chip?

Yes, most cards with chips can still be swiped. However, terminals are programmed to ask for the chip first because it's more secure. If the chip reader is broken, you can usually swipe as a backup. Some newer terminals no longer accept swiping at all.

Why does the terminal sometimes ask for a PIN and sometimes ask for a signature?

It depends on the transaction amount and your card type. Debit cards usually require a PIN. Credit cards often require a signature for larger purchases but may not require either for small transactions. Your bank and the card network set these rules.

What should I do if I accidentally leave my card in the terminal?

Most terminals automatically return your card after a few seconds if you don't remove it. If the card stays in the slot, alert the cashier immediately. They can retrieve it for you. Check that you have your card before you leave the store.
