The delegates see all the people they tap with, and the organizer sees how the event played out and how much networking happened—and it is a surprise to many organizers, in fact, how much people network. Blendology decided to use Plastic Logic’s off-the-shelf 4-inch display, which comes with a logic controller that serves as an interface between the badge and the Blendology app. The lightweight nature of Plastic Logic’s technology also makes the badges comfortable for delegates to wear around their necks for long periods, and the always-on display offers a clear, readable reflective display, similar to that of paper.
