Add Innofone to the Physical World Connection list.
I missed this story when Innofone acquired 2D code player Mobile Technology Group.
Mobile Technology Group just did a 2D code mobile ticketing campaign with Twelve Horses. 2D Data Matrix barcodes were delivered to mobile phones. They also provided a mobile ticketing campaign for Las Vegas Monorail
Quoting the release:
"Square in shape and made up of a pattern of smaller black squares, they are replacing with greater frequency the 1D barcodes found on cereal boxes and scanned in supermarkets everywhere.
2D Data Matrix barcodes are much more compact, can contain far more encrypted information, and are less likely to be misread. In other words, it's able to send more information in a smaller space more reliably with greater security and accuracy"
See why 2D codes will be adopted first?
