Abstract
A product label includes a semiconductor chip and an antenna. The semiconductor chip stores information about a product. The antenna transmits the information about the product to a reading device. The antenna has a predetermined breaking point at which the antenna can be destroyed during the reading operation by energy introduced by the reading device so that the product label can be read only for a specific number of read cycles. A method of producing product labels and a method for a contactless, forgery-proof identification of products are also provided.
