These bar codes are designed to be photographed by mobile devices and, as the technology evolves, passed to a variety of systems that can process the information contained in the bar code.
Note - for those of you who are not sure what a bar code does, traditional ones contain a variety of information than can be processed when scanned. A most typical example of these are the product SKU data, price, etc. contained in bar code on grocery items.
QR codes are not scanned, but when sent by a mobile device to a computer system these codes can be processed just as if they were scanned.
Why should you care? Well, consider the following examples of use, which at this point are not far off:
