Taiwan Trade Show Tries Virtual Exhibition Format

Visitors to the Taiwan International RFID Applications conference could use RFID to track their own movements, download information related to the booths they visited, and locate and contact colleagues.

Oct 23, 2008The Industrial Technology Research Institute (ITRI), a group funded by the Taiwan Ministry of Economic Affairs' (MOEA) Department of Industrial Technology, has demonstrated an RFID system that allows visitors at conferences and exhibits to track their own movements, download product brochures and other information related to the booths they visited, and determine the locations of friends and colleagues attending the show—as well as contact them. The system also enables exhibiting companies to measure booth attendance.

The system was piloted at the Taiwan International RFID Applications Show, held in Taipei. It offers what Tony Lu, ITRI's project leader for the pilot, calls a "virtual exhibition" scenario to help visitors see where they've been, and exhibit managers determine where people congregate.

Attendees could scan their RFID badges at the kiosk, see a map indicating which booths they had stopped at, download product information, and find and send messages to colleagues and friends.
"The system had been working well through the exhibition," says Henry Jan, senior manager of ITRI's business development division. In total, 51 exhibitors participated in the field test, and the group distributed 4,500 RFID-tagged badges to some of the 60,000 attendees who were said to have visited the show's RFID, photovoltaic and other electronics exhibits.

One theme of the RFID Taiwan event was sustainability, Lu says, and the system helped make that possible. Many exhibitors made a point of limiting the paperwork, brochures and other paper products they distributed to visitors. Instead, the exhibitors obtained e-mail addresses from attendees, or provided their own e-mail addresses and URLs so interested parties could gain electronic access to required information. In that way, the participating companies a large percentage of paper that would have been used and discarded.

The RFID tracking system was designed to make that process easier. During registration, each participating visitor was provided a badge with an Alien Technology ALN-9540 Squiggle RFID EPC Gen 2 passive UHF tag embedded in it. The visitors then wore the badges around their necks. ITRI deployed 71 EPC Gen 2 U-Port readers that it designed and built, installing them at booths throughout the exhibit floor, and also placing seven kiosks in key locations around the same area.

The readers, wired to computers that linked the data to ITRI's back-end system in the booths, captured the ID number on each badge as individuals browsed the booths. Each time an interrogator captured an RFID number, it stored that data in the back-end system. The ID numbers were linked to the visitors' nationality and status, such as "VIP" or "buyer," but not to their names. Participants could then visit one of the seven kiosks, scan their badges at the reader installed there, and select a trip report that would display a map of the exhibition and indicate which booths they had already stopped at, enabled by software developed by ITRI.
