Anyone buying a Pepsi Max soft drink over the next few weeks may notice the can or bottle has been stamped with an inch-square black and white collection of dots.
Train a mobile phone's camera on it and the dot acts like a barcode, sending a coded message to the phone which gives the drinker access to secret online content through their phone's internet browser.
Known as QR codes — for "quick response" — these little marketing widgets have been used in Japan for years on everything from magazines to tombs…
What? A new way of utilising the camera on mobile phones to lead you to specific web sites.
Why? Possibly a way of targeting our users? Although it would take them to install the software first, which hinders it.
