Abstract
An automatic product dispenser determines if the roll loaded into the dispenser is approved for use with the dispenser. The core of a roll receives a plug that engages a hub within the dispenser. The plug has a feature that alters an electromagnetic field created proximate the hub. The alteration of the electromagnetic field may then be used to determine if the plug, and thus the roll, is usable with the dispenser.
