Signature forgery feels like an old-fashioned crime in a digital-first economy, but it remains a common vector for financial fraud — forged signatures on cheques, loan documents, and account forms still cause real losses for banks and NBFCs every year.
How Signature Fraud Happens
- Cheque fraud — forging an account holder's signature to cash or deposit a stolen cheque
- Loan document fraud — forging a co-signer or guarantor's signature without their knowledge
- Account takeover — using a forged signature to authorize changes to an existing account
Why Manual Signature Checks Fall Short
A bank employee visually comparing two signatures is inherently subjective — fatigue, time pressure, and natural variation in a genuine person's own signature all make manual comparison unreliable at scale, especially across high transaction volumes.
How Digital Signature Verification Works
Digital signature verification compares a submitted signature against a reference signature on file — typically the one linked to a customer's PAN or bank account records — using consistent, repeatable matching criteria rather than a single reviewer's judgment call.
Layering Signature Checks with Identity Verification
Signature verification is strongest when paired with PAN and identity checks: confirming both that the signature matches on file and that the underlying identity behind the transaction is genuine closes gaps that either check alone would miss.
Warning Signs Worth Training Staff to Notice
- Signatures that are unusually slow or deliberate compared to the reference on file
- Pen lifts in unnatural places within a signature
- Inconsistent pressure or line quality suggesting tracing
How Veriqos Helps
Veriqos' PAN verification API includes signature matching as part of financial transaction checks, giving banks and NBFCs an automated, consistent way to flag signature mismatches before a fraudulent transaction completes.
Conclusion
Signature fraud hasn't gone away just because most transactions are digital now — it's simply moved to new documents and channels. Automated, consistent signature verification catches what manual review reliably misses.
