FIELD: biometrical sensors using integrated-circuit cards. SUBSTANCE: module meant to be built in integrated-circuit card has its substrate on section of sensory integrated circuit provided with at least one through window. Sensory integrated circuit is secured on substrate so that its active surface faces substrate and is so disposed on window section that it is easy to get at through substrate window. EFFECT: enhanced reliability. 4 cl, 4 dwg
