The invention concerns a manufacturing process for a contactless smart card (or
ticket) which includes the following steps:
- a manufacturing process for an antenna consisting in screen-printing
turns of an electrically conductive polymer ink onto a transfer paper sheet, and
then subjecting said support to heat treatment in order to bake and polymerize
said conductive ink,
- connection of a chip 14, provided with contacts, to the antenna
12,
- lamination consisting in 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,
- removal of the transfer paper sheet, and
- lamination of the card body onto the antenna support by welding at least
one layer of plastic material (18, 20) by hot press molding on each side
of the support.
