Microsoft Tag has moved out of the Beta stages with the release of Version 1. The new release also comes with a new Terms of Service as well. According to Microsoft, version 1 improves the Tag Reader, adds a Heat Map report, and makes it available in Italian, French, Spanish, Turkish and Simplified Chinese. The basic services for the Tag Reader will be offered for free.
The new ToS seems to simply transfer any tags created during the Beta program over to the ToS of the Version 1 release. You can find out more information on Version 1 at the Microsoft Tag website as well as downloading the Tag Reader directly from here.
