When the organizers of Intuit’s QuickBooks Connect conference initially decided to use near-field communication (N.F.C.) technology on attendee badges for this year’s event, which was held October 22 to 26 at the San Jose McEnery Convention Center in California, they had several goals in mind.First, they wanted to automate the process of tracking continuing education credits for the attendees; second, they wanted to make it easy for vendors to track leads at their booths; and third, they wanted a way for attendees to gather information from vendors and sessions electronically, rather than in paper form.
