Abstract
A method for manufacturing a radiofrequency identification device which includes a manufacturing process for an antenna which includes screen-printing turns of an electrically conductive polymer ink onto a transfer paper sheet, and then subjecting the support to heat treatment to bake and polymerize the conductive ink, connection of a chip 14, provided with contacts, to the antenna 12, lamination which includes 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, and removal of the transfer paper sheet.
