Electronic shelf label, system for electronic shelf label and method of operating system for electronic shelf label

摘要

The present invention relates to an ESL, a system for an ESL, and a method of operating a system for an ESL, which includes a first communication unit for receiving a first radio frequency signal having lower power than the second radio frequency signal and outputting a pattern signal generated by patterning the first radio frequency signal; a second communication unit for receiving the second radio frequency signal; a control module for controlling the ESL to perform a predetermined specific operation by receiving the pattern signal; and a display unit for displaying a screen according to the control of the control module, and provides an useful effect that only a specific target, which requires forced wake-up, selectively wakes up and furthermore performs predetermined operations.
