This disposable chip is designed to perform well when it is placed at least ½ inch away from the human body or metal. It works well when placed on the back of a bib, so long as the bib is not attached directly to a running shirt. For example, it works just fine on a bib placed on a winter coat or ski jacket. The K-Chip can be read at speeds up to 100mph at distances up to 25 feet.; It has a thin polymer label that will provide some protection from damage, but this chip is not meant to be submerged or used around water or sweat.This chip should never be used for mud runs. Instead, the KF-Chip is the proper choice.
