The Cblib team is pleased to offer customers the 3DSecure system free of charge. The complementary 3DSecure system has been introduced to guarantee a maximum level of security for all of our CBlib MasterCard®
The 3DSecure system is also referred to as ‘MasterCard® Secure Code™’, which is a payment method with added verification measures improving the security strengthening for each online purchase. An additional identification code (sent by SMS to the final customer) is required to validate each transaction. This allows further prevention of unauthorized use of your bank card and to ensure a high level of security.
