Strong Customer Authentication (SCA) is a form of multi-factor authentication required for merchants within the European Union (EU) who collect credit card payments from clients also within the EU. Payments that requires SCA can only be completed by the card holder.
Ubersmith integrates with a number of tokenized gateways that support SCA. SCA is not required for merchants or customers outside of the European Union.
Automated credit card charges, initiated by the daily invoicing script that trigger SCA challenges, emails your clients directing them to log into the Client Portal to complete the payment.
Unlike other automatic transactions that fail, SCA-challenged transactions are not added to the Retry Queue because they require the payer’s intervention. These failed charges appear in the Charge Log with the message prefix [3DSecure 2.0]. The rest of the message varies depending on the provider.
