Same card, added safety online.

Verified by Visa is a new service that lets you shop online with added confidence.

Through a simple checkout process, Verified by Visa confirms your identity when you make purchases at participating online stores. It's convenient, and it works with your existing Visa card.

Plus, Verified by Visa is a snap to use. You register your card just once, and create your own password. Then, when you make purchases at participating online stores, a Verified by Visa window will appear. Simply enter your password and click submit. Your identity is verified and the purchase is secure.

To activate Verified by Visa in your Visa card, or to learn more, contact the financial institution that issued your Visa card or visit visa.com/verified.
