FIELD: information technology.
SUBSTANCE: invention relates to the transfer of encoded data from a personal electronic device to a barcode scanner. Method of modulating display imagery for barcode simulation includes: receiving barcode information using an image sensor of a portable device; converting, by the portable device, the barcode information into discrete signals; processing, by the portable device, a discrete signal into formatted image data; displaying, in the portable device, an image based on the formatted image data; and modulating, in the portable device, the light characteristics of the image while simultaneously switching between the image and solid colour in order to simulate barcode information as simulated barcode light.
EFFECT: ensuring reliable reading of a bar code displayed on a display using scanners by increasing the contrast ratio between the bars and spaces of the barcode displayed on the display.
