In today’s digital economy, security is no longer optional. For businesses operating in or with the EU, Strong Customer Authentication (SCA) is not just a best practice — it’s a legal requirement.
Introduced under the EU Revised Payment Services Directive (PSD2), SCA aims to make electronic payments safer, protect consumers, and reduce online fraud. But what exactly does it mean, and how should your business adapt?
What Is SCA?
SCA (Strong Customer Authentication) is a regulatory standard that requires payment providers to verify customer identity using at least two of the following three factors:
-
Something the customer knows – like a password or PIN
-
Something the customer has – like a phone or smart card
-
Something the customer is – like a fingerprint or facial ID
This is essentially the framework for two-factor authentication (2FA), but mandated at the regulatory level for payments.
When Does SCA Apply?
SCA is enforced across the European Economic Area (EEA) and applies to most:
-
Online card payments
-
Bank transfers
-
Account access through web or mobile banking
However, several exemptions apply:
-
Low-value transactions (< €30)
-
Recurring payments with fixed amounts
-
Trusted beneficiaries added to a whitelist
-
Low-risk transactions based on real-time risk analysis by the payment provider
Understanding these exemptions is crucial for optimizing payment flow without compromising compliance.
Why SCA Is Critical for Merchants
If you’re a merchant accepting payments from EU customers, SCA affects you — even if you’re based outside the EU. Without SCA compliance:
-
Transactions may be declined by banks
-
You may lose customers due to friction at checkout
-
You could be exposed to chargeback risks
That’s why many platforms now integrate 3D Secure 2 (3DS2), which supports biometric authentication and in-app verification, making SCA compliance smoother.
