Check that black and white box
The square black and white Quick Response (QR) bar code that’s been popping up on packaging, in magazine ads, and even on websites, can be read by a cell phone equipped with a QR reader app. Those little codes simply provide more information about the product including links to see videos, coupon codes, or special deals. We wouldn’t be surprised if this Black Friday, retailers target “mobile” shoppers using their cellphones to research and purchase items.
