1. A management system for managing gaming chips, in which an authenticity recognition mark made of an infrared absorbing material is printed on an inner side of the outermost layer as internal printing, and an indication representing a type of the gaming chips is printed on the outer side of the outermost layer, the management system comprising:
a normal camera configured to record and identify an indication representing the type of the gaming chip printed on an outer surface of the outermost layer;
an infrared camera configured to record and discriminate the authenticity recognition mark by irradiating infrared rays from the printed side of the indication representing the type of the gaming chip printed on an outside of the outermost layer; and
an inspection device configured to determine the type and authenticity of the gaming chips using the normal camera and the infrared camera.
