INTERACT is a mobile app that allows event attendees to use their smartphones to capture contacts and content during events. Contact information is acquired by touching other attendees’ NFC event badges, or phone to phone. Content is acquired by touching a smart poster or an ITN BTAG (an NFC hotspot); or by proximity to a BLE beacon. The app also builds a complete timeline of the attendee’s NFC experience throughout the event. Besides contacts and content, the timeline includes the attendee’s booth visits, educational sessions attended; points scored in games, and tickets redeemed—all resulting from touches to the attendee’s badge.
