the cardholder’s bank (issuer),
the Merchant’s bank (acquirer), and
The primary goal of 3D Secure is to authenticate the cardholder’s identity during online Transactions, thereby reducing the risk of fraud.Thanks to the 3D Secure mechanism, the risk of fraud during online card Payments is significantly reduced, as Customer identity verification is required before completing the Transaction.
