Abstract: The present invention relates to a contactless smart card manufacturing process and more specifically to a manufacturing process for a contactless smart card for which the antenna is on a fibrous material such as paper. This process includes a manufacturing step to screen print the antenna onto the support, a step to bond the contacts of the chip onto the antenna support using conductive glue, and a step designed to laminate the card body onto the antenna support by hot press molding. Cutouts made in the corners of the antenna support prior to the lamination step enable the card bodies to be bonded together. The card thus obtained allows a posteriori viewing of any mechanical misuse to which it may have been subjected (extreme bending).

Abstract: A ticket providing access to a zone with controlled access when it is presented without contact in front of a scanner authorizing access to the zone, the ticket having an Edmonson format and including a paper ticket body covered on both surfaces with a protective coating. The paper ticket body is provided with a through recess where is located an electronic module including an integrated circuit and an antenna. The latter is formed by at least one turn obtained by screen printing with silvery powder in a polymerisable composition before being heat-cured. The ticket provides the advantages of being inexpensive to produce compared to a contactless access card and is highly biodegradable, which is essential for a disposable ticket.

Abstract: The present invention relates to a hybrid-contact contactless smart card manufacturing process and specifically a manufacturing process for hybrid-contact contactless smart card in which the antenna is on a fibrous material such as paper. This process includes a manufacturing step to screen print the antenna onto the support, a step to laminate the card body onto the antenna support by hot press molding, a step to mill a cavity in the card body opposite the side of the support bearing the screen print for housing a module comprised of a chip and a double-sided circuit and a step for inserting the module in the card. Cutouts made in the corners of the antenna support prior to the lamination step enable the card bodies to be bonded together. The card thus obtained allows a posteriori viewing of any mechanical misuse to which it may have been subjected (extreme bending).

Abstract: The invention relates to a contactless or hybrid contact-contactless smart card, including an antenna on a support, this antenna being formed by at least one turn of electrically conductive ink which is screen printed on the support, two card bodies 24 on each side of the support, each of the card bodies consisting of at least one layer of plastic material, and a chip or module 26 connected to the antenna. The support is made of paper and features cutouts 22 in each corner at which the two card bodies are welded together, thus giving its capacity to delaminate, when the card is bent, at the location where the forces were generated, which highlights any act of deliberate damage a posteriori as the card retains the traces of the bending, and represents a countermeasure against fraud.

Abstract: A data processing system is described. The system includes a smart card having at least two independent electronic modules. A way to connect the multiple electronic modules through the use of the reader is also disclosed. By using circuitry in the reader to perform the interconnection function, the overall complexity of the electronic functions on the card can be increased without increasing either the size of the individual integrated circuits or the difficulty of fitting them into a smart card.
