QR codes technology is awesome, many web sites and business are using it, it let you reach lots of people with just a black and white code. All your users are need to do is, pick up their mobile phone, then scan that QR code with the app and then they will get whatever you wanna say to them on their mobile phone screen, it could be link or any text message.
What if you can turn your real world into a commenting wall, suppose you were on a picnic and want to share your memories of it with the world, then you will think what if I generate a QR code for here and the people comes after you can scan it and then they will know what you wanna say and then they could also post comments on it.
