摘要

To discover specific data without wires for a water sports person (1) in the water (2), a data carrier scanned by a transmitter without wires acts as part of a transponder (6) fastened on part of the sports person's body (1a) or on a bathing cap (3) or arm strap (1b,1c). The data carrier contains data scanned by a transmitter emitting electromagnetic waves. This data encodes the person's ID, their location in the water and/or the time lapsed since the starting signal.
