3D Secure is a technology that provides protection against fraud and security of online payments. New Yelo cards are presented to customers automatically connected to the 3D Secure service, and the 3D code is sent to the cardholder without connecting to the SMS Alert service. When making an online purchase, an online store that supports the 3D Secure service will ask the customer to enter the code provided in the form of an SMS to the customer's mobile phone. The service is free of charge. The daily limit amount for transactions without 3D on sites that support 3D secure is applied according to the bank's current rates.
