Portable object comprising a near-field connection device

A portable object comprising a near-field communication device, the communication device comprising:

• an electronic chip;
• an antenna including ends configured to connect electrically to the electronic chip to form an electrical circuit;
• a mechanical control element configured to be displaced between two predefined positions including an active position wherein the communication device is activated and a passive position wherein the communication device is deactivated;
• a mechanical switch configured to switch between an open state and a closed state in response to a displacement of the mechanical control element between the two predefined positions, wherein the mechanical switch is a Reed switch;
• a permanent magnet configured to move relative to the Reed switch and configured to modify a state of the Reed switch in response to a displacement of the mechanical control element;
• and
• an elastic restoring element configured to return the mechanical control element automatically from the active position to the passive position.
