FIELD: digital data processing.
SUBSTANCE: invention relates to smart cards and contactless payment instruments operating on wireless data transmission technology. Smart card is made of a frame antenna, a semiconductor chip module, layers of sheet plastic, sheet lamination films, a sheet of ferrite film with an adhesive layer for fixing a contactless smart card, wherein the conductive wire turns are implanted in the plane into the plastic sheet serving as a substrate for the frame antenna implantation, and the semiconductor chip module is implanted into the plastic sheet serving as the substrate for the semiconductor chip module implantation, which is connected to the frame antenna by means of a direct connection due to a layer of thermally activated anisotropic glue applied to the reverse side of the chip module.
EFFECT: high reliability of the smart card owing to reducing the effect of interference on the operating circuit of the antenna and modifying the design of the card.
