Abstract
Apparatus for electronically transferring information between an electronic component and a reader. The electronic component is disposed on a substrate of a portable object, which substrate also carries a first antenna connected to the component. The reader includes a second antenna. The electronic information transfer is performed by inductive coupling between the first and second antennas, without electrical contact between the component and the reader. The reader includes a marker device suitable for writing a mark on the substrate in the event of the portable object being placed in the immediate proximity of the reader, and after information transfer is effected.

Apparatus for electronically transferring information between an electronic component disposed on a substrate of a portable object, which substrate also carries a first antenna connected to said component, and a reader including a second antenna, said electronic information transfer being performed by inductive coupling between said first and second antennas without electrical contact between the component and the reader, wherein said reader comprises:
- marker means suitable for writing a mark on said substrate when the portable object is placed in the immediate proximity of the reader, and
- control means responsive to a signal coming from a processor unit connected to the second antenna to cause said marker means to trigger writing of said mark on the substrate of the portable object in the event of electronic information transfer taking place.
