Patent

CA 2660662

The invention relates to a contactless portable object (10, 30, 60) comprising a main radiofrequency device composed of a main chip (18, 38, 68) and of a main antenna (16, 36, 66) that are connected together so that when the portable object enters the magnetic field of a suitable reader, the main radiofrequency device ensures the powering of the chip and the communication between the chip and the reader. According to the main characteristic of the invention, the portable object comprises a secondary contactless device comprising a secondary antenna (12, 32, 62) and an electrical circuit that are parameterized in such a way that, when the two antennas enter the magnetic field of a suitable reader at the same time, the quantity of energy required to power the electrical circuit so as to make it operate being less than the quantity of energy required to power the main chip (18, 38, 68) so as to make it operate, the electrical circuit is powered and makes it impossible to read the data of the main chip.

L'invention concerne un objet portable sans contact (10, 30, 60) comprenant un dispositif radiofréquence principale composé d'une puce principale (18, 38, 68) et d'une antenne principale (16, 36, 66) connectées ensemble de sorte que lorsque l'objet portable rentre dans le champ magnétique d'un lecteur adapté, le dispositif radiofréquence principale assure l'alimentation de la puce et la communication entre la puce et le lecteur. Selon la caractéristique principale de l'invention, l'objet portable comprend un dispositif secondaire sans contact comprenant une antenne secondaire (12, 32, 62) et un circuit électrique paramétrées de façon à ce que, lorsque les deux antennes rentrent en même temps dans le champ magnétique d'un lecteur adapté, la quantité d'énergie nécessaire pour alimenter le circuit électrique de façon à le faire fonctionner étant inférieure à la quantité d'énergie nécessaire pour alimenter la puce principale (18, 38, 68) de façon à la faire fonctionner, le circuit électrique est alimenté et rend impossible la lecture des données de la puce principale.
