Falsification safety providing method for product e.g. garment, involves assigning marking to identifier in set or deleted condition, and permitting read access on identifier by reader after authentication during set condition of marking

摘要

The method involves assigning a transponder to a product e.g. garment, and storing a clear, transponder-specific identifier (ID), which includes a safety unit e.g. check digit, on the transponder. A marking (F) is assigned to the identifier in a set or deleted condition, where a read access is permitted on the identifier by a reader only after an authentication (A) during the set condition of the marking. A binary variable is set as the marking, where the marking is set in a non-reprogrammable memory region and/or is secured against overwriting in accordance to a set hardware technique. An independent claim is also included for a transponder for the falsification safety for a product.
