Abstract
A method for making a hybrid contact/non-contact or non-contact smart card which includes a support (10,11) on which is produced an antenna, two card bodies (32, 42, 34, 44) on either side of the support, each of the card bodies including at least one thermoplastic layer, and one chip (30) or module connected to the antenna. The method includes the following steps: depositing a layer of a material having a major amount of resin on a predetermined zone (12,13) of the antenna support; making the antenna which includes screen-printing turns (14.15) and two connection pads (16,18,17,19) of conductive polymer ink on the zone previously produced on the support, and subjecting the support to a heat treatment to cure the ink.
Claims12
A method for manufacturing an antenna of a hybrid contact-contactless or contactless smart card that includes a support on which the antenna is made, two card bodies on each side of said support, each of said card bodies comprising at least one thermoplastic layer, and a chip or a module connected to the antenna,
- comprising the steps of:
- depositing a layer of a material consisting essentially of resin on a predetermined zone on said antenna support, said zone corresponding to the location where the entire antenna is to be printed or being slightly larger than said location,
- manufacturing the antenna, consisting essentially in screen printing turns and two connection pads of electrically conductive ink on said zone prepared beforehand on said support and subjecting said support to a heat treatment in order to bake said ink,
- wherein said layer of a material consisting essentially of a resin is more dimensionally stable than the antenna support at elevated temperature and pressure.
A hybrid contact-contactless or contactless smart card comprising an antenna on a support, said antenna comprising at least one turn of electrically conductive ink screen printed on said antenna support, two card bodies on each side of said support, each of said card bodies comprising at least one layer of plastic material, and a chip or module connected to the antenna
- wherein the antenna comprising turns and two connection pads of conductive ink is screen printed on a zone of the antenna support, said zone corresponding to the location where the entire antenna is to be printed or being slightly larger than said location and on which a material consisting essentially of resin has been deposited,
- wherein said material consisting essentially of resin is more dimensionally stable than the antenna support at elevated temperature and pressure.
