An identification input device and a temperature detector that detects body temperature data. The identification input device may be an optical touch pen. The infrared touch pen may be affixed to the temperature detector using a hook and connector or a snap fit connector. In use, the temperature detector computes body temperature data and the identification input device determines an identifier. The identifier is unique to a user. After obtaining the body temperature data and identifier, a transmitter may transmit body temperature data and the identifier over a wireless communications path to a processing unit. By transmitting data over a wireless communications path, an individuals data or a large group of data may be analyzed and viewed via a display unit.
