We are giving all of the attendees at ETech RFID tags that can be linked to their conference profiles (opt-in). With these tags you can interact with several projects we’ll have at the conference. BTW, ETech is happening March 9-12 in San Jose. Use et09pd30 at checkout for 30% off.

We were inspired to do this after I attended PICNIC in 2008 (Radar post) and got to experience first-hand the many, many uses of an RFID badge. Mediamatic linked your profile to it and that information was used to record your experiences. We got help from Mediamatic on our implementation and even used the same vendor.

If you make it to ETech here are the projects you can play with:

Lensley’s Photobooth: Leonard Lin’s new project is Lensley, a high-end photobooth with online photo-services integration. He’s creating a special version just for ETech that will tag photos with your name and tweet that you’ve just had one taken.

Personal Calendar: Radar’s own Edd Dumbill is the fellow behind the profile APIs. He is going to create a project that will show attendees their personal calendar at a public kiosk.

ETech Prophet: Josh and Tarikh of Uncommon Projects (they made the cool Yahoo! geo-bike) are adding an element of play to their project. They sent me a mail describing it as: “Essentially, we’d like to make an “Etech Prophet” a kind of mechanical turk idea (perhaps in another form factor)–you wave your RFID fob, it gesticulates, makes a noise and sends you your pithy fortune via twitter”

People Collector: This is a favorite of mine. Business cards are a waste of time and paper. I just want the person’s email address. Nothing else. The People Collector will be a mobile device that people can use to exchange contact information with other attendees. When you meet someone just wave your fob over their People Collector and a message will be sent to both of you. The People Collector will be built in Tom Igoe and Brian Jepson’s Hands-On RFID Workshop on 3/9.

Pulse: Attendees will be able to check-in to locations (this is all voluntary!). Overtime the system will build up information about attendees through their actions and will be able to generate a heatmap for the hotel. This project is being built by Alexander Biscelgie and Nick Sears.

Do you have something that you want to make? Let me know in the comments or find me on Twitter. We are still looking for projects.
