A Microsoft Tag is a High Capacity Color Barcode1; basically, a 2D barcode designed by Microsoft. The Microsoft Tag is similar to a QR code, in that, both are designed to engage users of print or physical media with digital / online content.
Microsoft Tags, however, are more easily customizable and provide more in depth analytics than QR codes; so, for some printed projects a Microsoft Tag may be more desirable because they integrate better with the design.
To create a tag you have to sign up on the Microsoft Tag website. This allows you track the analytics and discern the effectiveness of the tag.
