Manual Review Was Never Built to
Catch Document Fraud

Tampered scans, forged signatures, and duplicate submissions clear visual checks every day. Here's why.

Tampering You Can't See

Spliced scans and altered amounts leave no visible trace. Visual review passes them.

Signatures Nobody Verifies

Verifying a signature against records takes minutes. At volume, most are never checked.

Duplicates and Resubmissions

The same cheque or invoice, presented twice, paid twice, caught never.

Every Fraud Pattern Has a Detection Check Built for It

Expand a scenario to see the specific check that catches it, and what happens next.

Amounts in words and figures are cross-checked on every document. Any mismatch or physical correction is flagged, in line with RBI's no-alteration rule for cheques.

Before KlearStack

Eyeball Checks at Intake

Reviewers glance at each scan. Catching a forgery depends on who's checking that day.

Manual Signature Lookups

Signatures get compared by hand, and only when something already feels off.

Sampling and Post-Facto Audits

A fraction gets real scrutiny. The rest surfaces in audits and disputes, months later.

Escalation Queues

Anything suspicious waits for a second opinion, and the queue decides your turnaround time.

Verified business documents screened by KlearStack

Every document passes the same forensic checks automatically, inside the flow it already follows.

  • Every document screened, not a sample
  • Flagged in process, not in audit
  • Every check logged, audit-ready

What OCR Tools And LLMs Miss, KlearStack
Is Built To Catch

Generic OCR, IDP Tools, and LLMs

These tools read a document and return the data. Whether that document is genuine is a question they never ask.

  • Extraction only, no authenticity checks
  • LLMs: a different answer on every run
  • Documents leave for external APIs
  • No audit trail a regulator accepts

Every document is read, then interrogated: forensic checks, signature authentication, and cross-references run inside the same pass, and every result is logged.

  • Forensic fraud checks in the same pass
  • Deterministic results, every single run
  • On-prem and private deployment options
  • Field-level audit trail, ready for review
