1. A product label, comprising:
- a semiconductor chip for storing information related to a product;
an antenna operatively connected to said semiconductor chip, said antenna being configured to transmit the information related to the product to a reading device; and
said antenna having a predetermined breaking point, said antenna being destructible at said predetermined breaking point by energy introduced with the reading device during a reading operation such that the product label is no longer legible after the energy has been introduced.

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.

20. A method of producing product labels, the method which comprises:
-
a) fixing semiconductor chips to an antenna element selected from the group consisting of an antenna filament and an antenna strip, the antenna element including a plurality of rod antennas;
b) producing electrically conductive contacts between the semiconductor chips and associated ones of the rod antennas;
c) producing a cast film including a plurality of product label base elements such that, when casting a film for producing the cast film, a preliminary stage of the rod antennas produced in step a) is embedded in the film such that for each of the base elements there is a respective one of the rod antennas with a respective one of the semiconductor chips; and
d) separating the cast film into product labels. - View Dependent Claims (21, 22, 23, 24, 26, 27)

25. A method for a contactless identification of a product, the method which comprises:
-
providing a product label having a semiconductor chip for storing information related to the product, and having an antenna operatively connected to the semiconductor chip, the antenna having a predetermined breaking point;
transmitting, with the antenna, the information related to the product to a reading device for performing a reading operation; and
destroying the antenna at the predetermined breaking point with energy introduced with the reading device during the reading operation such that the product label is no longer legible after the energy has been introduced.
