Overblikket
Strong Customer Authentication (SCA) optimisation refers to the technical management of two-factor authentication requirements mandated under PSD2 in the European Economic Area and the United Kingdom.
This process sits between the merchant checkout and the issuer authorisation request, determining when a transaction requires a full 3DS challenge versus when an exemption can be applied.
By analysing transaction data such as the merchant category code (MCC), transaction value, and historical cardholder behaviour, an optimisation engine selects the appropriate SCA path. The goal is to satisfy the regulatory requirements of the issuer while maintaining the lowest possible friction for the payer.
Effective SCA management involves the use of Transaction Risk Analysis (TRA) and other specific exemptions to bypass redundant security steps.
This reduces the likelihood of cart abandonment caused by complex authentication procedures, ensuring that the necessary security protocols do not negatively impact the authorisation rates within the payments ecosystem.
Sådan fungerer det
Transaction data analysis
The system evaluates every inbound transaction for specific data points including the merchant category code, transaction amount, and geographic location.
This initial assessment determines if the transaction falls within the scope of PSD2 mandates or if it qualifies as an out-of-scope transaction, such as mail order or telephone orders.
Exemption engine application
The engine applies logic to identify eligible exemptions like low-value payments under thirty euros or recurring transactions.
If the acquirer supports Transaction Risk Analysis, the platform assesses the real-time risk level to request a friction-free flow, notifying the issuer that the transaction meets the threshold for an exemption.
Protocol version selection
The gateway determines the highest supported version of 3-D Secure, preferring EMV 3DS (3DS2) over older protocols.
This ensures compatibility with modern mobile banking apps and biometric authentication methods, which provide a significantly better user experience than legacy systems that rely on static passwords or SMS codes.
Dynamic challenge handling
If an issuer rejects an exemption request and returns a soft decline, the system triggers a platform-level retry with a full authentication challenge.
This automated step prevents a permanent hard decline, allowing the consumer to complete the two-factor authentication process and facilitating a successful subsequent authorisation.
Hvorfor det betyder noget
Authorisation rate preservation
Unoptimised SCA implementations frequently lead to higher decline rates because issuers may reject transactions that lack the necessary flags or authentication data. By correctly categorising transactions and applying the appropriate SCA tags, merchants maintain standing with issuers.
This technical precision reduces the risk of soft declines and ensures that legitimate transactions are not blocked by overly aggressive fraud filters or rigid regulatory interpretations by the issuing bank.
Conversion and friction reduction
The primary cause of abandonment during the payment phase is the introduction of additional steps. SCA optimisation focuses on maximising the use of frictionless flows, where the cardholder is not prompted for manual input.
By strategically using Transaction Risk Analysis (TRA) and low-value exemptions, businesses can process a significant portion of their volume without a challenge, directly improving the bottom line through reduced churn at the point of sale.
Anvendelser
Subscription based businesses
Merchant-initiated transactions (MITs) for recurring billing require specific SCA flags. Optimisation ensures the first transaction is authenticated correctly, while subsequent payments are marked as exempt, preventing recurring revenue loss from authentication failures.
High volume low value retail
Retailers with frequent transactions under thirty euros use SCA optimisation to skip 3DS challenges for the majority of orders, maintaining a fast checkout experience similar to one-click ordering systems common in established marketplaces.
Travel and hospitality
For hotel bookings where a card is stored for later charges, SCA optimisation ensures that the initial validation includes the correct permissions for subsequent off-session charges, reducing issues during the check-out or no-show billing processes.
Cross-border e-commerce
When selling into the European market from outside, specific SCA rules apply. Optimisation logic identifies the regional requirements of the issuer and applies the necessary 3DS protocols to ensure compliance and successful cross-border settlement.
I tal
This represents the typical percentage of transactions that can bypass manual authentication prompts through strategic exemption management within the European market.
Merchants often observe this range of improvement in successful authorisations when moving from basic 3DS implementation to an optimised SCA strategy.
The additional technical overhead for evaluating exemptions and selecting the optimal 3DS version is generally minimal and does not impact page load times.

Spørgsmål om SCA-optimering
Hvad er SCA-optimering?
SCA-optimering involverer strategisk anvendelse af Strong Customer Authentication for at overholde regler som PSD2, samtidig med at man sigter mod at minimere kundefriktion. Den bruger undtagelser og dynamiske udfordringer til at balancere sikkerhed med konvertering.
Hvordan gavner SCA-optimering forhandlere?
Forhandlere drager fordel af øget overholdelse af lovmæssige krav, reducerede svindelsrater og forbedrede konverteringsrater ved at undgå unødvendige autentificeringstrin. Det hjælper med at opretholde en gnidningsfri kunderejse, samtidig med at betalinger sikres.
Er SCA-optimering kun for europæiske transaktioner?
Mens Strong Customer Authentication primært er drevet af PSD2 i Europa, bliver dens principper vedtaget globalt. Cardflos SCA-optimering hjælper forhandlere med at overholde disse udviklende krav, uanset deres driftsregion.
Are recurring payments and subscriptions exempt from SCA?
Only the initial transaction in a subscription series, which is a cardholder-initiated transaction (CIT), requires SCA.
Subsequent payments are classified as merchant-initiated transactions (MIT) and are technically out of scope for SCA, provided the first transaction was correctly authenticated and the subsequent ones contain the appropriate original transaction ID references.
Optimisation ensures these links are maintained across the payment lifecycle so that renewal payments are not declined for lack of authentication.
How does the low-value payment exemption work in practice?
The low-value payment (LVP) exemption applies to transactions under thirty euros. However, the regulation includes counters; once a cardholder reaches five consecutive exempt transactions or a total spend of one hundred euros, the issuer must challenge the next payment.
An optimisation layer manages these requests but must be prepared for the issuer to refuse the LVP exemption once these thresholds are met, requiring a seamless transition to a full 3DS flow.
Does SCA optimisation affect PCI DSS compliance requirements?
SCA optimisation is a layer that interacts with 3-D Secure protocols and does not directly change the merchant's PCI DSS scope, provided the merchant continues to use a secure gateway or vaulting system.
By handling the 3DS payloads and exemption flags, the optimisation engine operates within the existing secure environment, ensuring that sensitive cardholder data remains protected while the metadata related to authentication and exemptions is managed.
