How do I safely use a credit card to pay for things online?

Direct Answer

Check that the website address has a padlock icon or "https://," enter your 16-digit card number, expiration date, and 3-digit CVV code on the back, and use a credit card (not a debit card) for federal zero-liability fraud protection.

Why You Might Want to Do This

  • To safely buy gifts, book travel, pay utility bills, or order items online with complete confidence.
  • To understand which card numbers to enter and how to avoid fraudulent checkout screens.

Before You Start

  • Have your physical credit card ready in your hand.
  • Make sure you are shopping on the official website of a reputable merchant (e.g. Amazon, Target, your doctor's portal).

Always prefer using a CREDIT CARD rather than a DEBIT CARD online. Credit cards offer federal $0 fraud liability and scammers cannot drain your actual bank checking account.

Step-by-Step Instructions

  1. 1

    Verify the padlock icon and website URL

    Look at the address bar at the very top of your browser screen. Make sure there is a lock symbol (🔒) and the web address begins with "https://" (the "s" stands for secure encryption).

    👀 Padlock icon next to website address in URL bar.

  2. 2

    Go to the Checkout or Payment screen

    Tap "Proceed to Checkout" or "Pay Now" in your shopping cart. Select "Credit or Debit Card" as your payment method.

  3. 3

    Enter Name on Card and 16-Digit Number

    Type your full name exactly as it appears on the front of your card. In the Card Number field, type the 16 digits (the spaces will format automatically).

  4. 4

    Enter Expiration Date (MM/YY) and CVV / Security Code

    Enter the 2-digit month and 2-digit year (e.g. 09/28). Then flip your card over and type the 3-digit security code (CVV) printed on the signature strip (or 4 digits on the front for Amex).

    👀 3-digit CVV number on the back signature strip.

  5. 5

    Review the total and tap "Place Order"

    Check the shipping address and final dollar total. Uncheck "Save card for future purchases" if you don't shop here often, then tap "Place Order" or "Complete Purchase."

    👀 Button labeled "Place Order" or "Complete Purchase."

If You Don't See It / Troubleshooting

If a website asks for your Social Security Number or ATM PIN to buy an item

STOP immediately and close the webpage! Legitimate shopping websites NEVER ask for your Social Security Number or ATM debit PIN.

If you ever suspect an unauthorized charge on your card statement

Call the customer service phone number printed on the back of your physical card immediately. The bank will cancel the card and issue a 100% refund for fraudulent transactions.

Good to Know

  • Major credit cards (Visa, Mastercard, Amex, Discover) come with $0 fraud liability protection by law.
  • Never send your credit card number or CVV code in an email or text message — email and texts are not secure.
