摘要： A contactless smart card has a sheet-like body containing an integrated circuit and an antenna via which the integrated circuit communicates with a terminal. The antenna lies in the plane of the card body and is constituted by several turns of a conductor that form a winding. A conductive bridge connects at least two turns of the winding to reduce its inductance. The card body includes a rupture zone that is designed to be broken when the card is first used. A portion of the connecting bridge lies within the rupture zone, so that it is broken when the rupture zone is broken during use.
