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.
