A plurality of wireless vital sensors for capturing biometric data of individuals is laid out and fixed at predetermined setting locations. The vital sensors are configured to sense the biometric data of an individual via non-contact when the individual enters the sensing area of any one of the plurality of vital sensors. Moreover, there is no discomfort while the wireless vital sensor is attached or no risk of damage to or destruction of the wireless vital sensor due to collisions during games. Additionally, the measuring device also includes the identification sensors for identifying a mobile object, and the individual corresponding to the biometric data sensed by the vital sensors is identified by the RFID data from the identification sensor. Accordingly, in a configuration where the wireless vital sensors can capture the biometric data of an unspecified number of individuals, which individual the biometric data belongs to can be surely identified.
