A secured identification document has at least two flexible layers embedding an electronic module. The electronic module includes a flexible substrate on which are positioned an antenna and a radiofrequency microcontroller storing identification data. The radiofrequency microcontroller is electrically connected to said antenna. The secured identification document has the at least two flexible layers locally joined together by means of a chemically and mechanically tamper proof material that is applied in cavities that are distributed in each of said at least two flexible layers that surround the electronic module in order to make the electronic module interdependent with the at least two flexible layers.

Secured identification document

A document with a cover having a first cover part, a second cover part, at least one internal page located between the two cover parts when the document is closed, a radiofrequency microcontroller, an antenna electrically connected to the radiofrequency microcontroller, and an electromagnetic shield capable of disrupting, at least partially, the wireless communication with the radiofrequency microcontroller when the document is closed and not disrupting the wireless communication when the document is opened. The electromagnetic shield is a wire grid. The wire mesh distance between each two adjacent wires of the wire grid is smaller than a radio-frequency wavelength used for communicating with the radiofrequency microcontroller, and is at least 0.1 millimeters and at most 40 millimeters.

Shielded contactless electronic document

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 document which includes a cover, one or more internal pages, a radiofrequency microcontroller, an antenna electrically connected to the radiofrequency microcontroller, an electromagnetic shield capable of partially disrupting wireless communication with the radiofrequency microcontroller when the document is closed, and not disrupting the wireless communication when the document is opened is described. The electromagnetic shield included in the document is implemented using metal, conductive plastic, conductive ink or magnetic ink.

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.

Method of manufacturing a data carrier

This invention relates to an integrated circuit device, in particular for manufacturing smart card electronic units for smart cards. It comprises:

Integrated circuit device, electronic module for chip cards using said device and method for making same

The invention concerns a method of manufacturing a module intended to create a portable object with chip and antenna. The portable object comprises an antenna and a chip placed on an insulating substrate. The antenna comprises a plurality of turns. The method comprises a first step in which an insulating substrate with at least one side is provided. The method is characterised in that it further comprises a second step in which an individual housing opening in the said side is made for each of the said turns and a third step in which said antenna comprising a plurality of turns is made by placing a conducting material in each individual housing.
