Enhanced security for your Internet operations The Caisse d'Epargne has strengthened its security system for on-line transactions. Thanks to the 3D Secure system, for Internet payments by credit card, authentication is carried out using a single-use code sent by SMS to your mobile phone. Your purchases by credit card on the Net are thus better protected: This authentication makes it possible to verify that the credit card is used by its legitimate owner. The principle is simple:
Step 1: For all your purchases by credit card, you must first inform: - the number of your credit card - its expiry date - the visual cryptogram (last 3 digits of the number on the back of your card)
Step 2: An authentication code with 8 characters is sent to you by SMS on the mobile phone you have declared to your bank.
Step 3: Enter this single-use code in the online authentication window that appears. The payment transaction can thus be authorized and validated.
