Geesh. You never know where you will find these QR Codes?
I just noticed the bananas we bought on Thursday at Publix have QR code.
Like everything there is good and bad that goes with it.
Amazingly, a QR Code can represent almost anything, not just numbers. But then you must have a machine to read it. Sigh.
After reading about QR codes (good ol' Google), I installed a free version on my iPhone. The code on the bananas goes to a recipe contest website.
Now that I know what they are, I see the codes everywhere.
