3-D Secure technology consists of the programs Verified by Visa and MasterCard SecureCode. After you enter your credit card details during the deposit process, a new window will appear, requesting your personal security code. Your financial institution will authenticate the transaction within seconds, as well as confirm that you are the individual making the purchase. If you haven’t yet registered with Verified by Visa or MasterCard SecureCode, you will need to activate this feature first. You can do this during the deposit process, or activate it in advance through your credit card issuing bank.
