Verified by Visa adds an extra layer of security to make it harder for someone else to use your Visa credit card to shop online in the unfortunate event your Visa credit card or account number is lost or stolen.
There is no special software to install. When you pay with your Visa card, the Verified by Visa service launches automatically at participating online stores. After you enter your Visa card number and submit your order, a Verified by Visa window will appear and your card issuer will display an authentication page.
Verified by Visa helps prevent unauthorized online use before it happens.
