Abstract: A management system includes a container unit, a sensing unit, a control unit, a signal display unit and a liquid pumping unit. The container unit has a container, a liquid substance and an information storing element. The liquid substance has material information recorded in the information storing element. The sensing unit has an information reader for sensing the material information when the sensing unit joined with the container unit. The control unit electrically connects the information reader to receive the material information. The control unit has a material judging module for judging whether the material information is correct in order to generate a judgment result. The signal display unit has a signal display module for outputting a predetermined signal according to the judgment result. The liquid pumping unit has a liquid pumping module selectively inserted into the container to pump the liquid substance according to the judgment result.
