## A real document, not a picture of one.

Each capture is checked before anyone looks at it: is this a physical card or a screen, a print or a scan; do the printed fields match the machine-readable lines; is the document valid and unaltered.

## What it does

- **Screens, prints and edits**: Photos of screens, printed copies, PDFs and edited images are flagged automatically.
- **Data consistency**: Printed fields are compared with the machine-readable zone, and dates and numbers are validated.
- **Reused photos**: A document image already seen in another session is detected and flagged.
- **Explained results**: Every check reports what it found, so a reviewer sees exactly why a document was flagged.

## FAQ

### What kinds of fraud are detected?

Photos of screens, printed copies, scans and PDFs, edited images, and document images already used in another session. Printed data is also checked against the machine-readable zone when there is one.

### Is a flagged document rejected automatically?

That depends on your rules. Most teams send flagged documents to review, where the reviewer sees exactly which check failed and why.

### Does an approved document prove it is genuine?

No automatic check can prove that. Approval means every check passed; the case keeps the evidence so a reviewer or auditor can look again.
