FIELD: instrument engineering.
SUBSTANCE: invention relates to smart swipe card designs. Invention is a device containing a microchip, placed on a substrate, and a loop antenna, the findings of which are connected to the conclusions of the microchip, a capacitor connected in parallel to the frame antenna and forming with it an antenna of a smart swipe card in the form of a resonant circuit, while the substrate is made in the form of a ring, on the outer surface of which are placed the turns of conductive material, forming a loop antenna and covered with an open shielding foil with a protective coating placed over it, forming a sealed enclosure.
EFFECT: technical result – increased operational reliability.
