smart card ricetrasmissione information, and its use in a management system of comprehensive structures

摘要

a ricetrasmissione card information, including memory means, and means of communication by electromagnetic waves.it also includes a microprocessor connected to the memory means and means of communication.and a source of electrical energy for the feeding of media and communication and memory of the microprocessor.the transmission of the card to a fixed system is preferably in a passive way through modification of the riflessivitu00e0 of an antenna.the card may be used to store information relating to a carrier and exchange this information with the possibility to modify or supplement them.in communication with fixed transmitter stations arranged in correspondence to physical gates controlled by them.the intelligence and autonomy of the card make it possible the management of complex systems or multi-purpose.the stations can be ordered in a hierarchical system, which ensures the possibility of autonomous operation of doors or sectors, even in the case of interruption of communication networkbetween the stations.
