Swiping a credit card may seem pretty obvious to many credit card users, but with new credit card payment options, like tapping your card or inserting your card, there may come a time when you have to rely on swiping the card but aren’t sure how. Let’s review the proper way to swipe your credit card when making purchases and buying gas at the pump.

How to swipe your credit card correctly

When making a purchase at a store, typically there’s a small payment terminal that faces the customer. To swipe your credit card correctly:

Position the magnetic strip (also called a magnetic stripe) that’s on the back of the card into the card reader’s slot so the magnetic strip faces toward the card reader. If the card reader lies flat, keep the magnetic strip on the bottom so the front of the card faces up as you insert it into the card reader.
If the card reader has a slot on the side, quickly move the magnetic strip through the card reader slot from top to bottom.

A card reader allows you to complete your transaction without needing to give your card to the cashier.

Wrong ways to swipe your credit card

There are wrong ways to swipe your credit card. If you swipe incorrectly, the card reader may make a beeping noise indicating couldn’t read the card and to try again. Here are some things to keep in mind:

Don’t face the magnetic strip away from the card reader when swiping.
Don’t face the magnetic strip up in the card reader.
Don’t swipe too slowly or stop and continue.

How to swipe a credit card at a gas pump

For drivers, paying at the gas pump is a convenient way to fill up without the need to go into the gas station. Most gas pumps have a card reader, but they may look different than one you might find at a retail or grocery store.

Gas pumps include a card reader with a small picture next to it of how to swipe or insert your credit card. Position your magnetic strip as indicated by the picture, then swipe or insert as shown.

Other ways to use your credit card

Most credit cards today have alternative ways to use them when making a purchase at a store. Along with the magnetic strip on the back of the card, credit cards may be chip-enabled and have an EMV^® chip on the front of the credit card.

These EMV chip cards can add an extra layer of protection when used at chip-enabled card readers. The chip helps protect against credit card fraud because it creates unique transaction data when you use your card at chip-enabled terminals in stores and at chip-enabled ATMs.

Some people call "EMV chip enabled cards “contactless credit cards” You can inquire about receiving a contactless Discover^® credit card.

An EMV chip has two different ways to complete a transaction. The first is to insert your card, chip end first, into a machine. You’ll leave your card inserted while the machine reads your data and only remove your card when the machine asks you to remove it.

The second is to tap the chip above a reader for a contactless payment. If a merchant isn't chip-ready, you can still swipe it to complete your card transaction like you have in the past.
