A QR code provides fast access, but a robust DPP also requires a persistent identifier, stable destination, structured data and controlled publishing.

## In brief

- Never point the printed code to a temporary file or campaign page.
- Keep the identifier and address stable while versioning content.
- Test size, contrast and scanning on the real product.

## Stable address, changing content

The printed code should resolve to an address controlled by the company, where new approved passport versions can be published without reprinting the code.


## Choose the right granularity

Decide before mass printing whether the identifier represents a model, batch or individual item, based on the use case and applicable rules.


## Assure print quality

Test the code on the final material, under wear and typical lighting, with several devices, HTTPS, a useful error page and privacy-conscious monitoring.


## Frequently asked questions

### Does the EU always require a QR code?

The ESPR refers to a data carrier and allows options such as QR codes or watermarks; product-specific rules determine the final choice.

### Can content behind the code change?

Yes, when changes are controlled and traceable; published versions should remain available as evidence.
