Microsoft has released an updated version of its iOS Tag Reader application.
The app, available in Apple’s App Store, now includes support for the iPod Touch 4G camera. Users will now need to use iOS 4 in order to take advantage of the “scan mode” in Microsoft Tag. Non-iOS 4 users will have to use the “snap” mode to scan in tags.
The idea behind the Microsoft Tag application is that you just aim your camera phone at a Tag and instantly access mobile content, videos, music, contact information, maps, social networks, promotions, and more.
Tag is similar to QR Codes, however Microsoft is using HCCB bar codes so instead of storing the data using square pixels it uses triangle shapes and colours. The difference is that Microsoft Tags don’t actually store the information. All it stores is a unique ID which it then sends to Microsoft’s servers. This way, you can include much more information, and more variety of information, then if it was just on the tag itself.
Microsoft recently revealed that its Tag technology has served over 2 Billion tags. Microsoft’s 2-D barcode technology is currently the publishing industry’s preferred technology. Microsoft Tag is also available for Windows Phone 7.
