Another way badges can increase effectiveness is through the addition of a Poken. The device attaches to a badge's lanyard and comes in dozens of conversation-starting designs such as a panda bear, a ninja, and a bumblebee (as well as a simple black-and-white model). The device uses near-field communication, so simply tapping two together exchanges the information stored on them, such as contact information, social network profiles, documents, videos, and Web sites. After the event, users plug the Poken into their computer's USB port to see all the people and information collected.
