The 3D Secure standard—often known by its branded names like Visa Secure, Mastercard Identity Check, or American Express SafeKey—aims to reduce fraud and provide added security to online payments. This means that sometimes you will be asked to enter a verification code before you can proceed with making a purchase or adding a card to your account. 

If you are not receiving the code, or the verification code is being sent to a number you no longer have access to, please contact the bank or company that issued the card you want to use. In the meantime, you will need to use a different card to continue with your Clearpay purchase or payment.
