I don't know how long these qr codes have been in existence. I remember seeing some on made in china electronics packaging. Until recently, they weren't so popular with normal users like me but google just did another good stuff using these in android. Since then, every one seems to like these. Newspaper's ads have these on side sharing website of their product. Blackberry uses these to show power of their smartphone.
I seem to like these. But you wud need a smartphone so the intended audience can't be dumb. Also saves effort of typing big urls.
There are potentially hundreds of ways it cud revolutionise. I like the concept of bringing industrial smart technologies for general users. It's like defence tech being used for public benefit.
if you own a smartphone, scan this. It's for you!
