In December 2008, Microsoft surprised a lot of people by releasing an iPhone app — Seadragon Mobile. A month later, they ensured the move wasn’t taken as a joke or gimmick by launching another app, Tag, into Apple’s App Store. Now, they have a few, including an app for Bing. And starting today, they’re doing the same for Android.
Microsoft’s Tag technology allows you to use your phone as a mobile barcode reader. You simply point your phone’s camera at a tag (think: a smaller QRCode), snap a picture, and the Tag program will interpret it.
