An electrically heatable aerosol-generating device for an aerosol-generating article is provided, the device including a device housing including a receiving cavity within a proximal portion of the device to receive at least a portion of the aerosol-generating article; a separating wall disposed adjacent to a distal end of the cavity, separating the cavity within the proximal portion from a distal portion of the device; at least one electrical heating device configured to heat an aerosol-forming substrate within the article when the article is received in the cavity; and sensing circuitry including a field generator disposed within the distal portion adjacent to the separating wall, the sensing circuitry being configured to measure a change of at least one property of the field generator caused by a presence of an indicator arranged within the article when the article is received in the cavity. An aerosol-generating system is also provided.
