Sorry for my reply. I'm also only F-Secure user (their home solutions).
I'm also not friendly with mobile platforms and QR-codes as such.
Just interesting: does this potential feature (QR Code scanner) should to do something more than well-known good trusted QR Code Scanner applications? For example, if there is URL - any security checks under F-Secure Security Cloud (from first) or something else.
Basically, it also can be valid for features like two-factor authentication / two-step verification. Maybe some security software applications can be with this 'bundle', but I able to think that possible to use well-known application with this design only.
