What We Catch
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.
The Amount Was Altered −
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.
The Scan Was Edited +
Pixel-level and compression checks identify spliced regions, erased fields, and digitally overwritten values before the document enters your workflow.
The Signature Isn't Theirs +
Signatures are authenticated against approved records and inconsistencies are routed for review with the evidence attached.
The Same Document, Twice +
Duplicate and near-duplicate detection compares every submission against prior documents, even when a file is renamed, rescanned, or lightly edited.
The Statement Looks Fabricated +
Cross-field checks flag impossible balances, manipulated transaction sequences, and internal inconsistencies in statements.
The Handwriting Doesn't Match +
Handwriting and ink-pattern checks surface entries that do not match the rest of a document or its trusted reference set.
The High-Value Cheque Problem +
High-value cheques can trigger deeper forensic screening and a policy-driven review path before approval.

Onboarding KlearStack
One Screening Layer Replaces the Patchwork
Here's how fraud control runs today, and how it runs once KlearStack is in.
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.
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
- No extra step for your team
- Signatures authenticated against records automatically
The Problem
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.
