Abstract
A method for connecting a chip (10) to a contactless smart card antenna having deformable contacts (18), the antenna being printed using conductive ink on an antenna support (16) made of deformable material. This method includes the steps of positioning the chip (10) provided with contacts (12) made of a non-deformable material, on the antenna support so that the contacts (12) are facing the contacts (18) of the antenna, and exerting a force on the chip (10) so that the contacts (12) deform the antenna support (16) and the contacts (18) of the antenna as a result of the pressure, the support (16) and the contacts (18) maintaining their deformation after the pressure is released, thus enabling a significant contact surface to be obtained between the contacts (12) of the chip (10) and the contacts (18) of the antenna.
