Disclosed is a code detecting system and method associated with moving objects. A light source provides light and sensor detects light as it reflects from a code supported by a moving object. Light from the light source reflects from a first portion of the code as the object moves, and is detected by the light sensor. Light from the light source reflects from at least a second portion of the code as the object moves, and is detected by the light sensor. A processor determines information representing the moving object, a first time when the at least one sensor detects the light reflecting from the first portion of the machine readable code and a second time when the at least one sensor detects the light reflecting from the second portion of the machine readable code. The speed of the moving object is determined thereby and displayed.
