If you have a company website, this is the ultimate marketing tool—if you don’t mind total strangers scanning you with their camera phones. When a cell phone scans an “Extended Identity” T-shirts, it will visit the coordinating website. The shirts feature a datamatrix barcode, known as a “tag”. Using a mobile phone camera, a person can take a photo of the tag which is read by software on the phone. From there, it launches a browser and takes you to the website.
