Facebook Tests Location Through RFID AT f8

All attendees of the f8 developer conference are receiving special RFID tags that enable them to check-in to various locations throughout the conference venue. The service lets you tag yourself in photos, become a fan of various Facebook Pages, and share activity to your Facebook profile. While it’s still a concept service, it’s interesting to see some of the things that Facebook developers are currently testing.

Facebook has been widely expected to make some type of location announcement today, yet there are no specific sessions dedicated to explaining how to implement location within Facebook. One can imagine that RFID would be extremely useful for enabling users to check in to various locations, however in its current form, there’s little disclosure on what each check in results in.
