Multi-Language

Two approaches for QR code multi-language support. First, dynamic QR code auto-routing: server-side detection of browser language (Accept-Language header) or IP-based region redirects to the appropriate language page - one QR code serves all languages. Second, landing page language switching: a language menu on the destination page as fallback when auto-detection errs.

Tourism QR codes particularly benefit - scanning a sightseeing sign shows Japanese to locals, Chinese to Chinese tourists, and English to Western visitors.
