good to hear that from you, because I could not find anything related in the net.
Well, the use case is a compact info format, e.g. for a visitor of our university with
-location, e.g. the coordinates of the building
-event, e.g. a special workshop
-URL, e.g. university website or event website
-Wifi, e.g. guest network or event wifi
-Public transport stations, e.g. Leopoldplatz, (this a part 1 of our student project, we can share soon as a spec)
-Contact, e.g. event coordinator
Usually this contact information is posted in the classic world as paper flyer/booklet/...
Part 2 of our student project here in Berlin is that a mecard container/package/collection type might be included.
After detecting the keyword collection in the class, the implementation can run the (location/wifi/URL/phone) profile detection in a loop and add multiple functions/buttons to the view.
I think, it is quite simple and useful, because QR codes can store already 4k and therefore could contain more profile infos and functions with a single scan.
If interested, we like to share the idea/implementation/source code with you. The semester ends mid of July, so we will have some specification proposals for that.
