Système 3-D secure
This is a protocol shared by banks allowing for an additional level of security to be offered for transactions carried out online. It entails asking the web user, in addition to their credit card number and visual cryptogram, for some information unrelated to the card itself, which only they would know. This additional authentication serves to ensure that the person in the process of carrying out the transaction is the actual cardholder.
