Many of us are always at conferences and meeting new people. Tag is a great way to share contact information during events like this. Above you can see that at Microsoft MVP day in India, badges had tags printed on them. This not only an a very efficient way of logging contact information, it is also a green way!
At this event participants were encouraged to share their MS Tag on their conference badges in
vCard format. This enabled other attendees to simply click the tag for getting
all the details for the attendee they are attending with.
