Memory card of the contactless type
First Claim
1. A contactless memory card, comprising a laminated card body of plastic material including a sandwiched support sheet having on one surface thereof a coupling antenna and integrated circuit with two contact pads connected to said coupling antenna, wherein the integrated circuit rests via said two contact pads directly on two conductive areas connected to the coupling antenna, and also rests on a least one additional compensation area that is not connected to said antenna, so that the integrated circuit lies substantially parallel to the support sheet, said integrated circuit and the support sheet being mechanically associated with each other by an adhesive material located in an empty space defined by respective facing surfaces of the integrated circuit and the support sheet.

Abstract
A memory card of the contactless type having a laminated card body of plastic material including a support sheet carrying a coupling antenna and an integrated circuit connected to the antenna. The integrated circuit has two contact pads resting directly on two conductive areas connected to the coupling antenna, and also rests on two compensation areas that are not connected. The integrated circuit and the support sheet are also associated mechanically with each other by an adhesive material disposed in the empty space defined by their respective facing faces.
