Card equipped with a contactless interface and method for manufacturing the card equipped with a contactless interface

A card equipped with a contactless interface, the card comprising an activation device, a microprocessor and an antenna, the activation device comprising:

• a first conductive component;
• a second conductive component;
• and
• a spacer in contact with a perimeter of the second conductive component,
• the spacer being configured to form lateral walls of a deformable cavity within the activation device, and the second conductive component being configured to form at least part of either a top or a bottom surface of the cavity;
• the cavity having a normal state and a deformed state, and at least part of the cavity being configured to separate the first conductive component from the second conductive component when the cavity is in the normal state;
• one of the microprocessor and the antenna being connected to the first conductive component when the cavity is in the normal state;
• when a force external to the activation device is applied to the activation device to move the first conductive component towards the second conductive component, the cavity being configured to transition from the normal state to the deformed state by deformation of the spacer, and at least one part of the first conductive component being configured to enter the cavity, thus forming an electrical contact with the second conductive component when the cavity is in the deformed state to establish an electrical connection between the microprocessor and the antenna;
• and
• when the external force stops being applied, the cavity is configured to return to its normal state, thus moving the first conductive component away from the second conductive component to break the electrical connection.
