Estimating the term…
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).
A manufacturing process of a hybrid contact-contactless smart card with an antenna support made of fibrous material such as the paper, including the following steps:
A smart card manufacturing process according to one of the previous claims, in which the antenna manufacturing step is conducted in reverse order and consists in:
A smart card manufacturing process according to one of the previous claims, in which the two sheets forming the card bodies on each side of said antenna support made of fibrous material are of different thickness.
A process for manufacturing a smart card according to one of the previous claims, in which, during the hot lamination step of the card bodies onto the antenna support, a third sheet of plastic material or varnish layer is added to each card body which acts as a cover.
A smart card manufacturing process according to one of the previous claims, characterized in that the plastic materials forming the card bodies is polyvinyl chloride (PVC), polyester (PET, PETG), polycarbonate (PC) or acrylonitrile-butadiene-styrene (ABS).
A smart card manufacturing process according to one of the previous claims in which the glue used to secure the module is a fluid cyanoacrylate adhesive, which is placed in the cavities prior to the insertion of said module.
