Encodes a store link. The honest advice is to point it at a landing page that redirects by platform rather than at one store, because a static code cannot know which phone scanned it.
How to make a app store qr code
That is the genuine limitation and most tools selling "smart" app QR codes are selling a redirect service to work around it, which reintroduces the thing static codes are good at avoiding: an intermediary that can go away, change hands or start tracking. If you control a web page, the free version is a page that checks the user agent and forwards to the right store: the code points at your own domain, keeps working if you change store links, and nobody else is in the path. If you only ever need one platform, pointing straight at that store link is simpler and perfectly fine.
Questions
Not by itself: a static code carries one URL. Point it at your own page that redirects by platform.
It works, but it puts a third party in the path who can change terms, disappear or start tracking. Your own redirect avoids all three.
Not if it points at your own page. That is the main reason to add the redirect.
No. The data is encoded in the pattern itself, so there is no redirect to go down and no account to lapse. A printed code works for as long as the paper lasts.
No. The code carries your data directly rather than pointing at a redirect service, so nobody: including us. Can count the scans.
