Make a short booth prompt in another language
Translate the guest action, not a page of technical settings.
A multilingual event can use a small set of clear instructions.
Write the essential source
Limit the card to where to look, how to start, when to change pose and how to collect the result. Keep button names consistent with the actual interface. Ask a fluent reader to check the translation and try a complete session. Literal wording alone does not prove the instruction is usable.
Check it in place
Print at a readable size and inspect the card from the guest position. Longer wording may need more space. Provide a demonstration and make posing optional. Keep helper troubleshooting separate, so the guest card remains a quick route through the experience.
