Idk if you could take a screenshot of the QR code for offline use? I always do this when buying public transport tickets in Europe.

- pc86 2y agoThe last half-dozen concerts I've been to have some sort of live code or something where screenshots don't work. I haven't spent enough time trying to deduce if the code itself changes or if the scanner just reads animation over the code, but at least for the moment you do need the live app to get into most concerts if they're using the Ticketmaster or Live Nation apps.
- crazygringo 2y agoIt's almost certainly the code that changes. That's easy to program and is very common in apps that produce scannable QR codes that they don't want duplicated, that will only work for the next e.g. 60 seconds. Any animation that could reliably be picked up by a scanning camera would necessarily be quite visible to the user. Just think of how QR codes often don't even work until you increase your phone's brightness, and they're as high-contrast as you can get...
