Verified by Visa protects your card against unauthorised use at participating retailers.
When you make a purchase in a shop, you enter a PIN number to confirm it's you. Verified by Visa does the same thing online, by asking you to authorise the transaction with a password.
To set up your Verified by Visa password, click on the 'REGISTER NOW' button on the right and follow the instructions. Once you're signed up, you'll be asked to enter your password when you shop online at participating retailers.
