For the security of payments, the Marie Puce website uses a bank card payment solution with the 3D secure device which allows a double identification of the cardholder via a secure one-time code. All transmissions to the banks are encrypted and secure. At no time is the customer's card number communicated or stored on the website.

The validation of the payment by the customer's bank can only take place after the customer has entered the secure code. The secure code is received by SMS or on the customer's bank application and must be entered within a very short time. If the customer fails to authenticate within the time limit, the payment is refused and the order is cancelled.
