New for TechEd 2011, we will be working with Microsoft Tag ( to create unique Tags for every session at the event. Your session Tag will appear on both the room signage and at the end of your presentation. With your session Tag, attendees will be able to scan as they enter the room to retrieve session details, view speaker bios, and engage in discussions; or scan at the end of the presentation to evaluate your session and download materials. We’re excited to integrate Microsoft Tag across the My TechEd mobile experience this year.
