Many event planners have adopted radio frequency identification technology (RFID) to provide them with information regarding the people who attend their events. RFID technology uses chips (tags) encoded with information that corresponds with an attendee's registration file. The technology gets event attendees through the entrance gates/admission process faster, collects extensive data on attendees concerning their purchases made with credit cards at an event, collects contact information of attendees, and allows vendors to have a deeper marketing analysis of the event attendees.
