Smart label and system made up of a smart label and a shielding element

Abstract

For improved durability during use in a microwave oven, and at the same time, good readability of a smart label, it is provided that a flat RFID inlay made up of an RFID chip and an antenna is applied to a metal shield that is made up of at least two mutually overlapping foil sections. A recess in the foil sections is enclosed by the antenna of the RFID inlay. When such a smart label with the metal shield is applied in advance to a microwave dish, and a shielding element that is impermeable to microwave radiation in the microwave oven is temporarily overlaid on the smart label from the opposite side, such a smart label can be used in the microwave oven without damage, but remains readable outside the microwave oven, and without the shielding element.
