How RFID Road Race Chip Timing Operates
From the opening start gun to the final finisher certificate: automated sports timing in 4 steps.
Bib Tag Encoding
Before race day, Gen2 UHF RFID inlays are programmed with participant bib numbers and attached to the back of Tyvek bibs with 3mm foam spacers.
Start Line Corral Crossing
When the gun fires, the master clock starts. As each runner steps over the starting ground mat, their personal chip time timer begins.
Ground Mat Interrogation
At the finish line, heavy-duty rubber drive-over mats project an electromagnetic field vertically upward to capture the passing tag at full sprint speed.
Instant Leaderboard Publishing
The sports timing software calculates official rank, split times, and pace per kilometer, automatically publishing live leaderboards online.
