At Mobile World Congress in Barcelona, Spain, in February, attendees could use their N.F.C.-enabled devices to access event information and download materials at kiosks, redeem food coupons at catering outlets, and participate in a treasure hunt. Organizers estimate 51,000 N.F.C. transactions were made during the four-day event. In addition, users could create an N.F.C. photo badge within the event’s mobile app, which expedited entry to convention facilities. Sponsor Incipio offered its Cashwrap N.F.C.-enabled cases for free so iPhone users also could participate.
