UPM Raflatac Provides RFID-based Tags for LA Marathon

ChronoTrack’s RFID time- and participant-tracking system solves these challenges with a lightweight, disposable “D” timing tag comprised of a UPM Raflatac UHF Gen 2 DogBone RFID tag and Impinj Monza™ 3 tag chip. All of the parts are secured to a piece of plastic and a highly durable adhesive strip by labelstock converter MPI Label Systems. Runners bend the plastic into a D-shaped form to secure it to the top of their shoelaces, ensuring that the tag is uniformly placed for optimal reading. As runners pass the five critical milestones, they run over ChronoTrack’s urethane ramps which use UHF antennas to transmit race data to Impinj Speedway® readers. Custom-designed ChronoTrack controllers then take the race data gathered by the readers and format it for use in scoring software packages.
