8. Digital business cards

Add some fun and efficiency to the traditional exchange of information by giving your attendees a Poken. The device attaches to a lanyard or key chain and comes in dozens of conversation-starting designs such as a panda bear, a ninja, and a bumble bee (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. It can also sync with mobile devices using the Poken app. Planners can create incentives for people to share their information by using the product's Game Pack.

10. Scavenger hunts

Mashable hosts a two-day conference each spring at Walt Disney World. The event, for about 300 senior-level executives from digital firms, brand leaders, senior-level marketers, and entrepreneurs, ends with a social-media-based scavenger hunt. In 2012, the networking activity took place at Epcot, where teams of five attendees worked to identify things in the park based on a set of clues and then posted photos of their findings on Instagram, tagged with #Mashcon.
