There are two types of prepaid Visa cards. Reloadable prepaid Visa cards are debit cards with a spending limit set by how much money you've have put into the card's account. Visa gift cards have a set spending limit that can’t be increased.
The key to using any prepaid Visa card for online purchases is that it must be registered under your name and billing address because many websites require this information, as well as the three digit CVV code on the back, for identity verification.
Safer Than Bank Debit Cards
Using a prepaid Visa card for online purchases eliminates the chance of problems with your checking account if your debit card information is stolen in transit while you're making Internet purchases.
Prepaid Visa cards offer the same purchase protection as regular Visa cards if you need to dispute a transaction.
Better Than Credit
Visa prepaid cards are debit cards and not credit cards, so it's just like using cash to shop online because you don't pay any interest.
Prepaid Visa Gift Cards
Many prepaid Visa gift cards don't work for online purchases because they're not registered to a particular person and/or billing address. You have to check with the company that issued the gift card to find out if you can register it to your name and address or not.
