Kort med en komponent, som er indrettet til genbrug

摘要

An electronic card which can be reused a large number of times incorporates a semiconductor circuit provided with an area which is erasable by means of electromagnetic radiation within the ultraviolet range of wavelengths. The externally-emitted ultraviolet radiation applied to the semiconductor circuit via a card recess passes through a quartz window and impinges on the erasable area.
