Strong 3DSV2 authentication:
limit the impact on conversion

Following the entry into force of the Regulatory Technical Standard of PSD2 (Payment Services Directive 2) on September 14, 2019, e-merchants must gradually apply strong authentication under the 3DS V2 protocol. The rules of the game are changing: it’s no longer the merchant who decides when to trigger strong authentication, but the issuing bank.

Dalenys, through its data infrastructure and proximity to the Groupe BPCE, allows you to anticipate regulations as best as possible, while preserving your conversion rates.

Dalenys benefits from the support of Groupe BPCE, 2nd largest banking group in France and largest Visa issuer in continental Europe. This environment gives Dalenys proven expertise in terms of issuers’ expectations: our experts can anticipate the format of payment flows that will avoid triggering a strong systematic authentication, and advise you on the best options to preserve your conversion.
