Abstract
A portable intelligent object has first and second communication interfaces with a station. The first communication interface can send and/or receive data by means of inductive coupling with the station. The object also has an integrated peripheral circuit. All of the data exchanged between the peripheral circuit and the central circuit passes through the station.
