Global 'Museum QR Code' Link Decay Rate
This page tracks the decay rate of QR codes used by museums worldwide, measuring how often they lead to broken links (404 errors) and how long it takes for institutions to update them. The data is gathered by scanning museum websites and checking QR code destinations against the Wayback Machine API to detect link rot. Understanding this decay helps cultural institutions maintain reliable digital access to their exhibits and highlights the hidden cost of temporary digital infrastructure.
