The Loopd Badge is a bi-directional sensor that is worn as a connected badge by attendees and also placed as a collection hub within speaker sessions, partner exhibits, or other areas of interest. The Loopd Badge exchanges contact information when users tap their Loopd Badges and place them nearby each other, and records an attendee’s event history as they visit speaker sessions, partner exhibits, or other areas of interest. Information can be exchanged between each Loopd Badge or via any connected hub in an area of interest.
