The chip card comprises a card body and an embedded chip module having a plurality of contact fields connected to respective terminals of the chip. The card body further comprises a positioning feature adapted to univocally identify said contact fields according to their location and orientation on the card body. The positioning feature is a hole or a notch formed on the card body in an area including the chip module such as a contact field which has no electrical functionality as contact field Caccording to ISO 7816-2. The invention is particularly adapted to card bodies including a plug-in removable portion of smaller size comprising said chip module and said positioning feature such as smaller size 'mini-plug' SIMs for mobile phones.

Mini-plug SIM card with improved positioning capability

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 method of manufacturing a data carrier from a support strip includes an overmoulding step, in which at least one support element of the support strip is overmoulded so as to obtain a data carrier body, and a microcircuit-connecting step, in which a microcircuit is electrically connected to the wiring pads of the data carrier body so as to obtain the data carrier.
