Abstract
The portable object includes an electronic circuit powered by an internal battery and having a data memory; it enables data to be interchanged with the outside without making direct electrical contact. It comprises a pierceable zone forming a region of the housing of the object, and a plurality of contact areas inside the housing and in register with the pierceable zone, the contact areas being connected to power supply lines for the electronic circuit, the areas being suitable for being put into contact with electrically conductive spikes connected to an external power supply circuit and pushed through the pierceable zone, thereby enabling the electronic circuit of the object to be powered and thus making good any exhaustion or failure of its internal battery, in particular in order to provide access to the data memory.
