There’s a little know Microsoft mobile product that doesn’t have an official name that I know of. So, I’ll call it Microsoft Cup. It is a passive mobile device designed to deal with both hot and cold liquids. If you look closely at Microsoft Cup’s display surface, you’ll notice a Microsoft Tag square on it. Tag is Microsoft’s homebrewed alternative to bar codes and QR codes. It uses colored triangles to embed coded information. Microsoft provides free apps for Android, iPhone, and their own Windows Phone 7 that can interpret Tags.
So, what does this tag embed? It provides a link to the current food special from Microsoft Dining Services: Veggie Stackers. As you can see in my screenshot I used an iPhone 4 to scan the Tag to demonstrate its ability to be read by non-Microsoft devices and platforms.
