Abstract:
1. A manufacturing method for a contactless smart card, comprising the following steps: creation of an antenna by screen printing turns of an electrically conductive polymer ink onto a transfer paper sheet, and then subjecting said transfer paper sheet to heat treatment in order to bake and polymerize said conductive ink, connection of a chip, provided with contacts, to said antenna, lamination of said transfer paper sheet with a layer of plastic material which constitutes the support for the antenna, by hot press molding, in such a way that said antenna and said chip are both embedded within said layer of plastic material, removal of said transfer paper, and lamination of the card body onto said antenna support by welding or sticking on either side of the support at least one layer of plastic material by means of hot press molding.
