Abstract

An electronic identification document is provided. The electronic identification document may include a carrier, an identification element, a microwave interaction structure configured to interact with microwave radiation, and an alteration element, wherein the alteration element may be part of or in contact with the microwave interaction structure and may be configured to alter, upon interaction of the interaction structure with microwaves, its state from an initial state to a permanent altered state, wherein the permanent altered state may differ from the initial state by a change of the alteration element in color, brightness, saturation, and/or transparency.
