A card body comprises a first card body (ID-1 card), a second card body (plug-in card) and a third card body (mini card). The first card body has a first shape (ID-1 shape). The second card body comprises a second shape (plug-in shape). The first card body encompasses the second card body. The third card body comprises a third shape (mini shape). The second card body encompasses the third card body. The third card body has a cavity for receiving an electronic module. A first boundary separates the first shape (ID-1 shape) from the second shape (plug-in shape), and comprises a first number of apertures () and a first number of notches (and) defining a first mechanical inter-card body coupling strength (link between ID-1 cardand plug-in card). A second boundary separates the second shape (plug-in shape) from the third shape (mini shape), and comprises a second number of apertures () and a second number of notches () defining a second mechanical inter-card body coupling strength (link between plug-in to cardand mini card). A cumulated length of the first number of apertures () is greater than a cumulated length of the second number of apertures () and a cumulated length of the first number of notches (and) is lesser than a cumulated length of the second number of notches () so that the second mechanical coupling strength is greater than the first mechanical coupling strength.

Progressive unplugging multi-cards body

A chip card includes a body of electrically insulating layers, one of which carries an open loop antenna having two ends. The body is equipped with a cavity for housing a micromodule adapted for connection to the antenna by two terminals. The micromodule includes an insulating substrate carrying, on a first side, a semiconductor component, and on a second side, several electrical contact pads. Two of the contact pads are disposed in a strip running through a center region of the substrate. The terminals are connected to the two contact pads through the substrate, and the two pads are respectively connected to ends of the antenna.

Chip card equipped with a loop antenna, and associated micromodule

The invention relates to a substrate for an electronic circuit ( ), the electronic circuit carrying at least one contact pad, the substrate comprising an insulating element ( ) housing the electronic circuit and carrying, on an external side, a conductive layer defining at least one contact region ( ), said contact pad being connected to said contact region. The substrate comprises at least one fragile zone ( ) disposed in the insulating element ( ). The electronic circuit substrate may be constituted by a chip card wherein an external readable button contains the electronic circuit. The chip card may cooperate electrically with a card reader.

Electronic circuit support comprising tear resistant means

Electronic microcircuit card and method for its manufacture

A flexible printed circuit having contacts and associated leads which are connected to the contacts. The contacts are disposed at a first zone and the leads are for connection from this zone to a second zone of the circuit which is at a distance from the first zone. The leads run from the respective contacts substantially perpendicular to the axis of the printed circuit which connects the two zones. The leads in turn form bends or loops in relation to the axis, up to the second zone.
