Dynamic QR codes for restaurant menus

Static menu QR codes are a trap: the moment a price changes or a dish sells out, the printed code is wrong. A dynamic code embeds a short link instead of the menu URL, so the destination can be edited at any time while the physical code stays identical.

That means reprints only happen when a table tent wears out — never because the kitchen changed the specials.

Create a code, paste your current menu URL, and print. When the menu changes, open the manager, edit the destination and save — the QR code never changes.

The code is the easy part. The page behind it is where restaurants lose guests, and the most common mistake is pointing a table code at a PDF of the printed menu. A PDF forces zooming and panning on a phone, thumbs never land on the right dish, and the analytics stop at the file: you cannot tell whether anyone looked past page one.

Serve a mobile page instead, and let a rule do the routing. One destination per language for the tourist tables, a separate page for drinks, and an allergen page that answers the question without someone walking to the kitchen.

Placement decides how a menu code performs more than the design does, because the scanning distance changes from 30 cm to five metres between a table tent and a window decal. A table code scanned from 30 to 50 cm is comfortable at 2.5 to 3 cm square; the same code on the window needs to be several times larger.

Proof it in the room, not on the screen. Print the proof, scan it with two different phones at the real distance, in the real light. Glossy lamination picks up every ceiling lamp, and a code under a candle's glare fails exactly when the room is at its busiest.

Scan counts answer staffing questions the till cannot. When people pick up the menu, which evenings are dead, whether the lunch board gets read at all: all of that is a scan count per day, and it costs nothing extra to collect.

The useful comparison is before and after. Move a code from the window to the table tent, wait a week, compare. That is how you find out a placement works, rather than guessing from how the room feels.

One code per venue is usually simpler than one code with rules, but the choice depends on what changes. If each site keeps its own menu, give each site its own code and name them clearly, so the manager editing tomorrow's specials is not one dropdown away from the wrong restaurant's page.

For a group spread over several countries, the same printed table tent can serve every site by routing on country, with a default page for anyone the rule does not catch.
