A QR code is simply a quick way of opening a link on a phone. Its value depends on what appears after it is scanned. Used well, it saves repeated questions and reprinting; used badly, it is just another square on the wall.
Where they tend to make sense
Restaurants. A digital menu can be updated without reprinting and offered in several languages. It is a good solution for price changes and dishes that sell out. Some customers prefer a paper menu, so it is worth keeping that option.
Short-term rentals. A digital guide brings together check-in instructions, the Wi-Fi details, house rules and local recommendations, which reduces repeated messages.
Services. A code on a laundry or repair shop ticket can show the status of an order without the customer having to call.
Dynamic or static?
A static QR code always points to the same address. That is why the safest approach is to point it at a page you control, on your own domain. You can then change the content without reprinting the code. If you rely on an external redirect service, check what happens to your codes if you stop using it.
Mistakes to avoid
- Opening a page that is not adapted to mobile. A PDF that is hard to read cancels out the advantage.
- Printing without testing. Try it with several phones and at the real scanning distance.
- Insufficient size or contrast. Leave a margin around the code and use good contrast.
- Not explaining what it offers. A phrase such as "View the menu here" inspires more confidence than a code with no context.
- Requiring an app to be installed. To look up information, a web page is usually enough.
How to get started
Identify the question your customers ask most often and see whether a simple page can answer it. Start with a single use and check that it is proving useful before extending it.
