1. An electrically heatable aerosol-generating device for an aerosol-generating article, the device comprising:
a device housing including a receiving cavity within a proximal portion of the device configured to receive at least a portion of the aerosol-generating article;
a separating wall disposed adjacent to a distal end of the receiving cavity, separating the receiving cavity within the proximal portion of the device from a distal portion of the device;
at least one electrical heating device configured to heat an aerosol-forming substrate within the aerosol-generating article when the article is received in the receiving cavity; and
sensing circuitry comprising a field generator disposed within the distal portion of the device 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 receiving cavity.
