3DS ACS
Issuing Side Security For CNP Transactions
Why does 3DS matter?
3D Secure
3DS enhances the checkout experience, providing increased security for both consumers and merchants. Serving as a form of multifactor authentication, 3DS effectively reduces both fraudulent charges and the resulting chargebacks. Moreover, when merchants adopt 3-D Secure, the liability for fraudulent chargebacks is transferred to the issuing bank. This is particularly beneficial, as chargebacks can incur substantial fees, nearly doubling the original transaction amount.
However, it’s important to note that 3DS introduces an additional step in the payment process, potentially contributing to higher cart abandonment rates. For businesses with higher chargeback rates, this trade-off is often worthwhile. On the other hand, streamlined payments may be more cost-effective for certain businesses in the long run.
Access Control Server
Role of ACS
In the dynamic realm of online transactions, the Access Control Server (ACS) stands as the vanguard for cardholder authentication. The Access Control Server (ACS) resides within the issuing bank’s domain. The issuing bank, responsible for the card the cardholder is using, plays a vital role in authenticating whether the card is associated with the authorized cardholder.
Diverse Authentication Methods
The ACS ensures flexibility in authentication methods, utilizing either one-time codes or account login procedures. This adaptability allows for a tailored approach, catering to the diverse needs and preferences of cardholders.
The Mandatory Role of Card Issuers
Every card issuer is mandated to maintain an Access Control Server, emphasizing the critical role it plays in the 3D Secure ecosystem. Compliance with industry standards ensures that the cardholder authentication process is not just a necessity but a robust and secure practice.
The Process
When an Authentication Request is received, the ACS takes charge, employing either a challenge flow or a frictionless flow to verify the legitimacy of the transaction.
Customers then verify their identity by providing information such as their account password or a code sent to their email or phone to the ACS.
By comparing this information with the records available to the issuing bank, the ACS signals whether the customer has successfully verified their identity.
