geo.country

One poster, three country pages

The same artwork in Switzerland, in Germany, in France — one print run. A scan from CH lands on .ch, from FR on .fr, every other country on the mandatory rule. Not on an error page.

Where it hangs: Poster, banner, packaging that sits in more than one country.

Why the paper stays: Country-specific URLs on the poster mean three print jobs.

Country of the scan

A paper poster on a concrete wall, carrying the code — **The same code on every shot.**Poster, banner, packaging that sits in more than one country.

The ruleset

Valid, storable, mandatory rule last.

Not a description of what the engine could do — this is the text a code carries. The first matching rule wins, and the last one always matches.

Only the country. Region and city do not exist as an axis: below country level everything falls apart on a phone, and an axis you cannot trust is worse than none.

Also

Same axis, different situation.

Recycling note: CH the PET line, DE the yellow bag, otherwise the generic page.
Prices per market: One design, three shops. The paper does not know which one.
Legal text: What has to be shown differs by country. The code does not.
