May 27, 2004 American start-up nTAG has produced an interactive name badge for conferences and social events that significantly improves the quality of people-to-people connectivity. Based on years of research at MIT's Media Lab, nTAG brings social technology into the business event arena where both host and attendee derive numerous benefits compared to the paper badges of the past. While stimulating conversation between attendees, nTAGs also help organisers to deliver event information, track attendance, manage security, send messages, and evaluate surveys and polls in real time. Worn like regular paper badges, nTAGs exchange data with one another using infrared sensors. As attendees approach each other, information is automatically transferred from tag to tag, requiring no action from the wearer. Then the tags' LCD screens illuminate and display information on shared interests -- "Hi Karen, we both work in the fashion apparel industry."
