FIELD: computer equipment.
SUBSTANCE: invention relates to design of non-contact smart cards. Card is made in form of ring and comprises microchip on dielectric substrate, frame antenna, which outputs are connected to microchip outputs, capacitor arranged on a dielectric substrate connected in parallel to the frame antenna and forming with it an antenna of the contactless smart card in the form of a resonant circuit, wherein dielectric substrate is made in form of ring with coils of current-conducting material, forming frame antenna, protective housing made in form of a ring is made of current-conducting material and has a transverse process section filled with dielectric material, as well as an internal annular recess, in which a dielectric substrate with a microchip is fixed, frame antenna, capacitor and coils of current-conducting material.
EFFECT: technical result is wider range of technical means, which can be used as contactless smart cards.
