XR device, electronic device and control method thereof

An XR device, comprising:

• a transceiver;
• a display;
• memory;
• an optical sensor including a receiver for detecting an optical signal encoded as a barcode and an emitter for outputting the optical signal encoded as the barcode;
• and
• a processor electrically connected with the transceiver, the display, the memory, and the optical sensor,
• wherein the processor is configured to:
• generate a service request signal including a first code for device connection, and output the service request signal through the emitter,
• identify a second code indicating user information from a service response signal received through the receiver, and
• based on the user information identified from the service response signal corresponding to user information previously stored in the memory, control the transceiver to transmit a message for requesting a wireless connection to an electronic device providing the service response signal.
