Internet shoppers can use a Visa credit card or a Visa debit card to make online purchases. Debit cards use your current account as a funding source; credit cards work like temporary loans. Thanks to HTTPS and SSL technologies, online transactions are safer and more secure than ever before. If you have enough money in the bank, and you have a Visa debit card, use it on any website that accepts Visa credit cards.
Verify that you see "HTTPS" instead of "HTTP" in the URL of the website. This insures that you are using a secure site.
Locate the site's shipping information section and verify that the company ships to your location. Read its shipping cost information and review the shipping options.
Click the "Checkout" button when you are ready to make your purchase. This will take you to a checkout screen. Fill in your name, address and other information requested on the checkout form.
Enter your Visa credit card number and expiration date in the supplied fields. The credit card number is on both sides of your card. The expiration date is below that number.
Enter your security code in the "Security Code" field if the form requests it. Some sites do not need this number. The security code is a three-digit number on the back of the card next to the credit card number.
Press the "Submit" button after verifying that all of your information is correct. Most sites will take you to a final screen where you can confirm your information. If you see this screen, review your information and click "Submit" to process your card.
Write down the confirmation number that the site gives you after it processes your card.
Visa recommends that you print a copy of the final transaction page. If you do not have a printer, click "File" and the "Save" to save a copy of the page to your desktop. You can later open this page in your browser by double-clicking it.
