Im not an Internet expert. How does MasterCard SecureCode work?
MasterCard SecureCode is quick and easy to use. You don’t need a new card or any special software. Once you’ve registered for the service, your personalised SecureCode window will appear when you make a purchase from a participating MasterCard SecureCode online retailer. You just need to check that your Personal Message appears correctly, and then simply enter your SecureCode. Once your SecureCode™ is verified by Clydesdale Bank to validate your identity, you can proceed with your purchase with added confidence – easy!
