Supplement system and device

A reader device comprising:

• a housing sized to mate with a container defining a plurality of chambers enclosed by a cover, the cover supporting a plurality of paths, each path associated with and extending over each chamber;
• a first lead supported by the housing and extending outwardly therefrom, the first lead positioned to be associated with the plurality of paths;
• a plurality of second leads supported by the housing and extending outwardly therefrom, each second lead positioned to be associated with a path of a respective chamber;
• and
• a controller supported by the housing and in communication with the first lead and each of the plurality of second leads, wherein the controller is configured to (i) determine that one of the chambers in the container has been opened in response to a first electrical signal between the first lead and one of the second leads, and (ii) determine that another of the chambers is unopened in response to a second electrical signal between the first lead and another of the second leads.

A membrane for covering at least one chamber of a container, the membrane comprising:

• one or more layers formed from an electrically non-conductive material;
• and
• one or more paths supported by the one or more layers, each path extending from a first end to a second end, each path formed from an electrically conductive material;
• each path comprises a conductive ink printed onto the one or more layers;
• an adhesive layer attached to the one or more layers opposite to the one or more paths;
• wherein the first ends of each path of the one or more paths are interconnected to one another, and the second ends of each path of the one or more paths are spaced apart from one another;
• and
• wherein the first ends of the one or more paths are radially spaced apart from the second ends of the one or more paths.
