Just think....
you could have ONE yellowpages printed every 5 years... just keep updating the codes that are already in the pages...
IMAGINE...(once people know about codes and start using them daily)
just think....I own a grocery store....I create a magnet that sticks on a fridge with a 2D barcode linking to the grocery store...
I run out of milk.... click the code, find out how much milk is THAT DAY (because the code can be updated every minute if needed) and I also find out that bread is on sale today, AND there is a coupon for $2 off Ice Cream!!!!
Im not the most optimistic person on this board... but man, if this thing actually starts getting off the mat it could be HUGE!
