Microsoft launches Tag app on Android
Tag for Android is the first Microsoft-made application launched on the mobile platform. This is notable because Android is the mobile platform by Microsoft’s chief rival: Google.
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. This can be used to place things like coupons in physical locations, for example. Other companies, including Google, are working on these mobile barcodes as well. In fact, just prior to the Nexus One unveiling, all Google employees were given the device with a special barcode on the back that other Android devices could scan to get that person’s information.
