FIELD: transport engineering; load identification systems. SUBSTANCE: invention relates to identification system of carried loads passing by automatic data readout station for operative tracking the dislocation and providing checking of preservation of loads carried by rail cars, containers, van trucks, etc. Proposed electronic mark has coder connected through modulator with transmit-receive antenna. Said coder contains clock-pulse generator, programming unit connected with memory matrix, binary counter connected with clock-pulse generator, decoders of insertion, columns and lines, switch connected with decoder of insertion, memory matrix and code converter connected with adder. Outputs of adder are connected with inputs of modulator. Third input of switch is connected with output of state control unit of electronic locking-and-sealing device. Invention provides electronic mark used as identifier of locking-and-sealing device or critical part of vehicle providing optimum ratio between range of readout, service life and required rate of irradiation of reader. EFFECT: improved reliability of load tracking. 4 cl, 2 dwg
