FIELD: chip-cards engineering.
SUBSTANCE: antenna on substrate has at least one coil of electric-conductive paint, applied to antenna by template method, two card bodies on each side of substrate, each of which has at least one plastic layer, a micro-chip or module, connected to antenna. Substrate is made of paper and has slits in each corner, on level of which by soldering two card bodies are connected, which allows card to divide in layers in place of greatest bending load.
EFFECT: higher efficiency.
