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.
