How it works

A perfect-looking bill can still be fake

Editing an address on a PDF takes seconds. So Fraudfinder checks the document's structure, as well as what it says.

printed ≠ decoded
Barcode ≠ printed address
01

Barcode decoding

Many bills carry their details inside a barcode. When the barcode and the page disagree, we flag it.

Letref
"Rather than scouring through docs, often taking two people an hour or so, we can run them through Fraudfinder and if it comes back as high risk, it confirms our suspicions were correct. We rely on our judgement in conjunction, but it certainly has cut down the time spent, often from an hour or so to a few mins."
