In my previous blog, I outlined the basic requirements of the new obligation, brought in under PSD2 (the second Payment Services Directive), for all payment service providers to apply strong customer authentication (SCA) in certain circumstances. SCA has to be applied both when accessing payment account information and when initiating a payment transaction meaning that a customer checking their account and then paying a couple of bills would have to go through SCA multiple times in one session, which is far from ideal on the user-experience scale. To avoid this, you, as a payment service provider (PSP) can apply one of nine exemptions, if circumstances permit.
Strong customer authentication (SCA) is a valid attempt by the EU to curb electronic payment fraud, including ‘card-not-present’ fraud. From a glance the concept is fairly simple, it will be a regulatory obligation to apply two factor authentication (2FA) to the electronic payment process. However, it’s not all quite as simple as that as SCA has more requirements than just the frequently touted 2FA. This blog will provide the basics on SCA and subsequent blogs will go into more detail on the exemptions and how SCA differs from simple 2FA.
