  • Electronic shelf label and controlling method therefor
    Patent number: 12676089
    Abstract: An electronic price indicator according to an embodiment includes a display displaying product information, an NFC module configured to communicate with a user terminal, a Bluetooth module configured to communicate with the user terminal, and a processor configured to control the display to display the product information received from the user terminal through the Bluetooth module. The processor is further configured to release a sleep mode when receiving an interrupt from the user terminal through the NFC module, and perform Bluetooth communication with the user terminal by initiating a scan for a predetermined period of time to receive an advertising signal from the user terminal.
    Type: Grant
