Abstract
A contactless smart card includes a card body, an antenna and an integrated circuit chip connected to the antenna's connecting terminals. The connecting terminals of the antenna are further connected to conductive via holes emerging at the card surface. A junction based on an electrically conductive substance is flush with the card surface and connects the conductive via holes. The electrically conductive substance is designed to be removed by scraping, and prevents the card from being used until it is removed.
