QR-pedia is fantastic, one of few applications were QR-codes make sense!
Of the options I would prefer number 3 and then number 2. ¨
With an apologetical text aqdded to option 3 if possible.
When I scan at the moment I get option 1, i.e. the phone tries to search swedish wikipedia with the original article name, so even if the article would exist I guess it wold not find it?
