# QR code use cases

Scenarios where a QR code is printed once and has to keep working for years. Each guide covers placement, sizing and what to link to.

- [Product packaging Codes on cartons and labels that stay live for the product's whole shelf life. View use case](https://permanentqrcodes.com/use-cases/packaging/)
- [Product user manuals Setup guides and videos behind a code on the box or the device. View use case](https://permanentqrcodes.com/use-cases/product-manual-qr-code/)
- [Restaurant menus Table codes for menus you update without reprinting. View use case](https://permanentqrcodes.com/use-cases/restaurant-menus/)

## What these guides cover

A use case is a specific job for a QR code, such as a link on a shipping carton, a setup video for a product, or a menu on a restaurant table. These guides go one level more practical than the industry pages. They show where to place the code, how large to make it, and what the scanner should land on.

Packaging codes have to last as long as the product sits on a shelf or in a warehouse. Manual codes have to keep pointing at the right model after a revision. Menu codes change often, so the destination matters more than the printed pattern. In each case the printed pattern stays fixed and only the page behind it changes.

If your job is not listed, start with the format guides under QR Code Generator and pick the closest match.
