The present invention relates to a set of security documents. Each security document within the set having an optical code, notably a barcode, which is neither connected nor coupled to any electronic chip that may be carried by the security document. The optical code on each security document within the set encodes the same information for the same optical reader. Each security document having different respective electromagnetic signature, these signatures being unique to each of the security documents.

Item comprising a barcode with an electromagnetic signature

The invention concerns a method for manufacturing a radio frequency identification device (RFID), the device featuring an antenna and a chip () connected to the antenna, the method including the following steps:

Reinforced radio frequency identification device support and its manufacturing method

A method for manufacturing an identity booklet cover provided with a radio frequency identification device having an antenna and a chip () connected to the antenna, the method including the following steps:

Radio frequency identification device support for passport and its manufacturing method

A method for connecting an electronic chip () to contacts (and) of an electric circuit, the chip having two conductive plates (and) located on the last layer of the chip and at least one electromagnetic shielding layer, at least one of the plates (or) being entirely covered with an electrical insulating layer (). The method includes placing an adhesive dielectric material () on the circuit between the contacts (), to fix the electronic chip () relative to the circuit, positioning electronic chip () on the circuit so that conductive plates (et) are opposite the contacts (and), so as to create between the chip and the electric circuit at least one capacitive link made up of the conductive plate (or), the electrically insulating layer and the contact (or).

Method for connecting an electronic chip to a radiofrequency identification device

A radio frequency identification device support () featuring an antenna () screen-printed on a support () and a chip () connected to the connection terminals (and) of the antenna. According to a main characteristic of the invention, a thermoplastic layer () and a top layer of synthetic paper () are laminated on the antenna support () so that the antenna and the chip are trapped in the thermoplastic and the three layers (and) cannot be separated and so that the device is resistant to water and humid environments.

Radio frequency identification device support and its manufacturing method

A radio frequency identification device support () featuring an antenna () screen-printed on a support () and a chip () connected to the connection terminals (and) of the antenna. According to a main characteristic of the invention, a thermoplastic layer () and a top layer of synthetic paper () are laminated on the antenna support () so that the antenna and the chip are trapped in the thermoplastic and the three layers (, and) cannot be separated and so that the device is resistant to water and humid environments.

The invention concerns a radio frequency identification device (RFID) featuring an antenna () screen-printed on a fibrous support and a chip () connected to the connection terminals (and) of the antenna. According to the main characteristic of the invention, a thermoplastic layer () and a layer of paper () are laminated on the antenna support () so that the antenna and the chip are trapped in the thermoplastic and so that the device is resistant to water and humid environments.

Radio frequency identification device resistant to humid environments and its manufacturing method

A multi-step method for producing contactless tickets or cards, the tickets or cards including a chip () which is connected to an antenna () on a paper carrier. The method includes: printing the antennae in series on the paper carrier strip using a silkscreen ink; fixing a chip to each ticket by connecting bond pads of the chip to the antennas' bond pads (); and covering the paper strip, including the silkscreen-printed antenna and the corresponding chip, with an adhesive paper strip. After each step, the paper carrier strip is wound up before the next step is begun. Each of the silkscreen-printed antennae is coated with a protective layer () to prevent silkscreen ink from being transferred to the back of the paper carrier strip during the successive winding-up following each step.

Method for producing a contactless ticket comprising a chip

The invention concerns a radio frequency identification device (RFID) including a chip () and an antenna () connected together on a support, the antenna being printed onto the support and the support being fixed to an object with an added attachment means. According to the main characteristic, the attachment means overlaps at least once at least one turn of the antenna so that the radio frequency identification device (RFID) is destroyed if the support is detached from the object without the attachment means being removed.

Secure radio frequency identification device for identity booklet or object to be identified

A method for manufacturing a radiofrequency identification device which includes a manufacturing process for an antenna which includes screen-printing turns of an electrically conductive polymer ink onto a transfer paper sheet, and then subjecting the support to heat treatment to bake and polymerize the conductive ink, connection of a chip 14, provided with contacts, to the antenna 12, lamination which includes making the transfer paper sheet integral with a layer of plastic material 16 which constitutes the support for the antenna, by hot press molding, in such a way that the screen-printed antenna and the chip are both embedded within the layer of plastic material, and removal of the transfer paper sheet.

Method for manufacturing radiofrequency identification device using transfer paper and radiofrequency identification device produced using this method

Method of manufacturing a chip card having an antenna support, two card bodies and an electronic module or a chip linked to the antenna. This method has a first lamination step which includes fusing two thermoplastic sheets (or) on each side of antenna support (or) at a temperature sufficient for the thermoplastic sheet material to soften and to flow wholly so as to eliminate any differences in thickness from the support, and a second lamination step carried out after a period of time necessary for the thermoplastic sheets (or) to be solidified, the second step including fusing by hot pressing two plastic layers (or) making up the card bodies onto the plasticised and even faces of uniformly thick antenna support (or) plasticised by the thermoplastic sheets.

Method of producing a contactless chip card or a contact/contactless hybrid chip card with improved flatness

The invention concerns a manufacturing process for a contactless smart card (or ticket) which includes the following steps:

Method for producing a contactless chip card using transfer paper

A smart card including an antenna () on a support made of paper type fibrous material (), two card bodies on each side of the support each consisting of at least one layer of plastic material having a low flow temperature, and an electronic module () featuring a chip connected to the antenna, the assembly made up of the antenna support and the two card bodies being welded together by hot-lamination under pressure. The support made of fibrous material includes at least one opening () such that the plastic layers () of the card body come into near perfect contact during the lamination operation, the opening forming a weld between the card bodies thus reinforcing the connection of the module.

Contactless or hybrid contact-contactless smart card with reinforced connection of the electronic module

A method for connecting a chip ( ) to a contactless smart card antenna having deformable contacts ( ), the antenna being printed using conductive ink on an antenna support ( ) made of deformable material. This method includes the steps of positioning the chip ( ) provided with contacts ( ) made of a non-deformable material, on the antenna support so that the contacts ( ) are facing the contacts ( ) of the antenna, and exerting a force on the chip ( ) so that the contacts ( ) deform the antenna support ( ) and the contacts ( ) of the antenna as a result of the pressure, the support ( ) and the contacts ( ) maintaining their deformation after the pressure is released, thus enabling a significant contact surface to be obtained between the contacts ( ) of the chip ( ) and the contacts ( ) of the antenna.
