Inside the tiny RFID chip that runs San Francisco’s race

How does a tiny chip time the runners in the Bay to Breakers race? In this article, I take die photos of the RFID chip used to track athletes during the race. Bay to Breakers is the iconic San Francisco race, with tens of thousands of runners (many in costume and some in nothing) running 12km across the city. To determine their race time, each runner wears an identification bib. As you can see below, the ba ...
