US Patent 11185112 Consumable identification

An aerosol-generating device includes an interface, one or more pairs of conductors, and electrical circuitry. The interface is configured to receive at least a portion of a consumable. The consumable comprises one or more conductive portions arranged to identify the consumable. The one or more pairs of conductors define at least a portion of one or more circuits. The one or more pairs of conductors are selectively electrically couplable with the one or more conductive portions of the consumable if the consumable is received by the interface. The electrical circuitry is configured to identify the consumable based on completion of the one or more circuits defined by the one or more pairs of conductors and the one or more conductive portions if the consumable is received by the interface.
