FIELD: personal use articles.SUBSTANCE: attache case contains a registration device installed so that to exclude the possibility of the attache case opening without such registration device removal. The registration device includes a body consisting of two electrodes (one of them conjugated with the attache case outside), separated with a dielectric insert and forming a capacitative sensor element that is electrically connected to the power supply, the inductive communication interface winding and the electronic unit for measurement of the sensor element capacitance and information processing and storage (all the three positioned inside the body and interconnected); the registration device is installed so that to exclude the travelling suitcase opening without such registration device removal. Fitted onto the registration device body is a protective cap protecting the capacitative sensor element against the effect on interferences.EFFECT: reduced temperature dependence, improved operational characteristics of the registration device.3 cl, 3 dwg |
