The optical-code protection device against counterfeiting comprises an information code carrier made as a photoresponsive polymer-based identification card with addition of luminophor where the selected binary code by respective previous flare and word capacity by amount of identification marks is defined, an optocoupler for check of identification labels, an optocoupler of luminescence control, a modulator, the output being simultaneously connected with the optocoupler for check of identification labels and the optocoupler of luminescence control, a digital analyzer, the input being connected to an optocoupler of luminescence control, a flare unit. Besides, it comprises a thermoplastic layer-code reading detector, the input being connected to the optocoupler for check of identification labels and the thermoplastic layer-code reading detector, the input being connected to a digital analyzer output, a comparing unit, the first input being connected to a thermoplastic layer-code reading detector output, the second input is connected to a photoresponsive polymer-code reading detector output and the output is connected to the flare unit and a modulator blocking input, a signalling device of quality products and a signalling device of production counterfeiting production and a re-use. |
