At this year's HOPE hackercon in NYC, participants were asked to wear RFID-enabled badges that followed them around and spied on them as part of the Attendee Meta-Data (AMD) project. Now the project has released the data it gathered, as well as the sourcecode for the devices and their readers.
The AMD social networking site lets visitors "tag" themselves based on a diverse set of interests. Old-school hackers, network security experts, cryptographers, political activists, law geeks, lockpickers, reverse engineers, bloggers, privacy advocates, and far more–visitors can label themselves with multiple interests, to become discoverable by fellow visitors from around the world with similar interests, in the same room or across the building. Attendees can then use email or text messages to "ping" the people they discover on the site–new contacts and old friends alike.
(Thanks, Aestetix!)
