Ingenico prides itself on being confirmed PSD2 compliant since 29 May 2018.
One of the key requirements of PSD2 relates to Strong Customer Authentication (SCA) that is required on all electronic transactions in the EU from September 2019.
This means your customers will no longer be able to make a card payment online by using only the information on their cards. Instead they will have to, for example, verify their identity on a bank app that is connected to their phone and requires a password or fingerprint to approve the purchase.
