FIELD: physics.
SUBSTANCE: reflective display includes, at least, surface protective coating, data display layer, reflecting layer and back protective coating. Radio-frequency identification module or modules are mounted on these layers or in-between. Each of the modules said above integrated radio-frequency identification circuit or circuits and communication antenna or antennas connected to the specified integrated radio-frequency identification circuits. Behind reflecting layer there is irradiator provided. This layer reflects the light impinging from the sign front and transmits the light travelling within the sign.
EFFECT: data identification of various signs at night and possibility for high-level data exchange through simultaneous reading and recording electronic data.
