I always am interested in barcode recoginition technology, especially put it to iPhone.

Do you support 2D bar code such as QR now ?

Is this project open source now ?

Hi Forrest,

We added 2D barcode (most popular) to our roadmap but we don’t support it yet.

This is not an open source project.

I have forwarded your comment to our marketing team.

Thanks,
Aleksey

Hi,
Nice project, would be interested if you also provide the source code. I mean how can we use the result printed from the program for our own cause? Thanks
