What is Verified by Visa and Mastercard Secure Code?
CES (Secure Electronic Commerce)

CES is a system to secure Internet transactions promoted by International Visa and Mastercard among others. The main purpose is to provide greater security both to the Internet user and to the businesses that sell through the Internet by authenticating the buyer as the legitimate owner of the card they are using.

In practice, when paying with a "secured" VISA or MASTERCARD card, you will be asked, in addition to the number and expiration date, for a personal password exclusively for Internet purchases that identifies you, unequivocally, as its owner. In this way, no one will be able to make a purchase on the Internet if they do not know the password. You will be able to distinguish if the Secure Electronic Commerce protocol is activated by the VISA “Verified by VISA” and Mastercard “Mastercard Secure Code” logos.

If you have not yet received a personal code for exclusive use for Internet payments, we advise you to ask your financial institution to add your cards to the Secure Electronic Commerce service. To do this, you can contact your bank or if you are an electronic banking customer, you can request it directly online.
