<p>In a device (1) which uses consumable material, an electronic device (24) is attached to the packaging (20) of the consumable which stores information about the consumable, and the quantity remaining in the packaging. The device is thus capable of reading such information and updating it by decrementing a counter of the electronic device (24) and optionally responding accordingly, i.e. if the wrong type of consumable is used.</p> |
