The system of the present disclosure includes a container and an electronic component with a partial power source in the form of dissimilar materials. The container includes a liquid. Upon contact with the liquid, a voltage potential is created and the power source is completed, which activates the system. The electronic component controls the conductance between the dissimilar materials to produce a unique current signature.本發明的系統包括一容器及一電子構件,其具有相異的(dissimilar)材料形式的部分電源。該容器包括液體。在與該液體接觸時,一電壓電位(voltage potential)被產生且該電源被完成,其將該系統啟動(activate)。該電子構件控制該等相異的材料之間的電導率(conductance)以產生一獨一無二的電流特徵(current signature)。
