Abstract
The present invention relates to a contactless smart card manufacturing process and more specifically to a manufacturing process for a contactless smart card for 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 bond the contacts of the chip onto the antenna support using conductive glue, and a step designed to laminate the card body onto the antenna support by hot press molding. 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).
