When Should Payment Providers Rethink Identity Verification?

The mule account has quietly become the center of a regulatory shift that changes what “having identity verification” needs to mean for payment providers. Frameworks converging in 2026 — the UK's Payment Systems Regulator rules, the EU's incoming PSD3, evolving interpretations of US Regulation E — are moving the same direction: institutions are judged on whether onboarding actually prevented fraud, not on whether a procedure was technically followed.

Pain Point

The regulatory signal for payment providers in 2026 isn't a single company's scandal — it's a shift in what “compliant onboarding” is actually judged against.
Regulators are converging on a single principle across jurisdictions: accountability for outcomes, not just procedure — meaning a PSP that “followed its KYC process” is no longer automatically in the clear if a mule account still opened.
Mule accounts, whether opened by complicit individuals, manipulated victims, or synthetic identities, underpin the majority of payment fraud schemes moving through legitimate-looking accounts.
Client onboarding systems built purely for speed, without genuine identity checks behind the speed, are exactly the vulnerability regulators are now pricing into enforcement.
A payment provider that can't show how its process for onboarding customers actually screens for synthetic and stolen identities is negotiating from a weaker position as this liability shift continues.
The trigger here isn't a single fine to react to after the fact — it's a regulatory direction that's already set, making “our onboarding technically complies” a weaker defense than it used to be.

How It Works

What this liability shift actually asks payment providers to build is specific:
Id verification software that confirms a real applicant behind every account, fast enough to support speed onboarding software without trading away genuine verification.
A KYB onboarding solution running for business accounts and merchants in parallel with individual verification, since mule and synthetic-identity schemes increasingly use both.
A client onboarding system that documents exactly how each identity was verified, so a payment provider can show regulators the check that happened, not just that a checkbox was ticked.
Fake id detection and document cross-checks tuned to catch synthetic identities — real data fragments combined into a fabricated whole — not just obviously forged documents.
The providers positioned well for this shift are the ones whose customer onboarding software was already built to prove verification happened, not just to complete it quickly.

False Positives

Reacting to regulatory pressure by adding friction indiscriminately just trades one problem — mule accounts slipping through — for another: legitimate customers and merchants abandoning onboarding because every applicant now gets treated as a potential risk. The regulatory shift asks for better verification, not more of it.

Business Impact

An onboarding process that can demonstrate outcomes, not just procedure, to regulators applying the new accountability standard.
Reduced exposure to mule-account liability as UK PSR rules, PSD3, and Reg E interpretations converge on institutional responsibility.
A documented client onboarding system ready for the kind of scrutiny this regulatory shift is bringing.
Faster, cleaner onboarding for legitimate customers and merchants, since precision protects conversion as much as compliance.

How Finchecker Solves It

Finchecker's identity verification pairs id verification and KYB onboarding in one client onboarding system, built to prove genuine verification happened — not just to move applicants through quickly. As liability shifts toward outcomes, that documented, dual-layer verification is exactly what payment providers need to show.
