Abstract: A method of verifying authenticity of an object including: a) a step of filling a database of a verification server comprising: physically associating an object with an electronic tag containing unique digital identification data IDobject; acquiring a photograph Pobject of the object, followed by acquiring the digital identification data IDobject; sending the pair (IDobject, Pobject) to the verification server to be recorded in the database; and b) a subsequent step of verifying the authenticity of the object comprising: acquiring a photograph Pproduct and digital identification data IDproduct of the product by acquisition means; sending the data Pproduct and IDproduct to the verification server; using the verification server to compare the photograph Pproduct with the photograph Pobject associated with the digital identification data IDproduct equal to the digital identification data IDproduct of the object and stored in the database.

Abstract: A network of antennas for contactless reading or writing of RFID tags in a detection volume, including three or four flat, independent antennas sequentially connected to a single reader by a switch, wherein planes of the antennas pass through a reading/writing/detection volume centered in the detection volume, for every pair of antennas, an intersection of their planes is included in the optimal reading/writing volume, and the antennas are arranged so that any direction in the optimal reading/writing volume forms an angle of about 45° or less with at least one of the planes of the antennas.

Abstract: A contactless RF-ID label including an antenna and a computer chip, wherein the antenna extends in three spatial directions.
