Abstract

A golf ball (G) has incorporated therein an IC chip ( 3 ) which can input and/or output data relating to at least one item selected from among manufacture history, shot history and flight properties. The ball's own possession of inherent information facilitates operations including ball quality control, ball recycling, and evaluation of flight performance.
