Not to burst the bubble for you, but we have seen such projects before and so far I haven't heard any success rate. What makes your project unique though?
As a consumers though, I definitely don't want to see counterfeit products specially drugs and medicine.

So you are really tacking a menace in the society and it is worldwide problem. There are companies like Systech who specializes in brand protection, partnered with big pharmaceuticals to combat this issues but so far its not been successful. So I do hope that your project will take off to at least reduce this problem in the next 5 - 10 years so best of luck!!!
Come to think that solving worldwide problem wont really be that easy.We arent discouraging but this one would need lots of determination.
Combating counterfiet neither goods,medicines etc. is a good motive but as said it still havent resolved out. Issues/problem does still exist.
About QR scanning, its still a complicated thing to be perfected, lots of holes actually.
