SCA (Strong Customer Authentication)
A European regulatory requirement under PSD2 mandating two-factor authentication for electronic payments. Authentication must use two of: knowledge (PIN/password), possession (phone/card), or inherence (biometrics). Applies to EEA and UK transactions. Various exemptions exist: low-value transactions, trusted beneficiaries, transaction risk analysis, and recurring payments. 3DS2 is the primary implementation method.
3D Secure (3DS)
An authentication protocol that adds a verification step during online card payments. The cardholder authenticates via their bank (password, SMS code, biometrics). 3DS2 is the current version, offering frictionless authentication for low-risk transactions. Mandatory in Europe under SCA/PSD2 requirements. Shifts fraud liability from merchant to issuer for authenticated transactions. Can impact conversion rates but reduces fraud.
Open Banking
A framework enabling third parties to access bank account data and initiate payments with customer consent. Mandated by PSD2 in Europe. Enables account-to-account payments bypassing card networks. Growing as alternative payment method. Benefits include lower fees than cards and real-time payment confirmation. Adoption varies by market.
