But...um...why?

It turns out with the Google smart phone app (and the Bing smartphone app too) you can point the phone's camera at a bar code and Google will tell you what the bar code says. For example, you can point the camera at the bar code on a tin of Twining's English Breakfast tea and Google will tell you, "Twining's English Breakfast tea." 

Also, if you point the camera at the label on a Dole banana, Google will tell you "Dole banana." And as an extra added bonus, no extra charge, it will tell you that the word, "Dole," on the label says "Dole."

Dude!
