Title: A VESSEL FOR PREPARATION OR COOKING OF E.G. FOODSTUFFS AND BEVERAGES BY HEATING, AND AN IDENTIFICATION CARRIER FOR USE WITH SUCH VESSELS
Abstract:
A method to control a heating procedure in an oven by using an optically readable information carrier with or on the heating object, said object having an identification marking that cooperates with a reading device within the oven which permits function of the oven only by meeting one or more identification requisites. The oven may be provided with an optical reading device for touchless reading of the information carrier prior to and/or during the heating procedure. By providing the information carrier with one or more fields that exhibit color shifts at preselectable temperatures a feedback control of the heating procedure while using simple technical solution is made possible.
