Welcome to the home of J-Chip, the world's most accurate and reliable sports timing system.


J-Chip is designed for timing marathons, road/trail running, road bike racing, mountain bike racing, triathlon, mud/obstacle racing, cross-country skiing, snowshoe racing, and more. Our customers successfully use J-Chip at events in the United States, Asia, Europe, South America, and Australia.


J-Chip can be used to produce real-time results at events both large and small. Our customers regularly provide ‘live’ results online (including split points from multiple remote locations), live leaderboards on large-format screens, text messaging results to interested parties, instant results kiosks, and even posting results to participants’ social media pages.
