Fourthline’s end-to-end KYC solution streamlines the entire process


Onboarding flow

The Fourthline KYC process begins with a fully customizable onboarding flow that collects over 210 data points needed to confirm your customers’ identities, including biometrics, document information, whereabouts, device metadata and more. Fourthline’s web or mobile KYC onboarding application guides customers through a fast and thorough data submission process built with user experience and accessibility prioritized to deliver industry-leading conversion rates without sacrificing fraud detection accuracy.

Verification and analysis

Fourthline next executes a three-tier verification process—over 99% automated through proprietary technology and AI algorithms. After determining whether the ID is genuine or fraudulent, we conduct biometric analysis to match the ID photo to the person who submitted it. We then run a set of checks to uncover anomalies and inconsistencies. These steps comprise a 5AML- and GDPR-compliant process that fulfills all relevant regulatory requirements. Applying years of financial crime data to these checks delivers the most comprehensive set of information to substantiate whether you can—and want to—accept a customer.

Proof of Address

Outcome and decisions

Based on your compliance requirements, risk appetite and existing processes, Fourthline designs customized decision-making and reporting protocols. These protocols address everything from the right balance between automated and human checks, to reliance versus outsourcing arrangements, full audit trails, risk scoring, tailored escalation protocols, and custom reporting. We don’t just return flags, but an actual verdict on even the most challenging clients.


Fourthline’s KYC approach goes beyond initial customer sign-up and verification. Through proprietary post-onboarding techniques and database checks, Fourthline catches an additional 20 to 30 percent of fraud attempts. With daily screening against PEP/sanctions lists and Fourthline’s own fraud database, combined with practices like rebinding, re-KYC, and remediation, Fourthline continues the fight against fraud throughout the customer lifecycle.
