Abstract

Provided is a device for transmitting wireless power. The wireless power transmitting device includes a communication unit, a power receiving unit, and a processor. The processor is configured to obtain, through the communication unit, communication establishment information and location information associated with a wireless charging area from a tag device, establish, through the communication unit, communication with a wireless power transmitting device based on the communication establishment information, and control to transmit the location information to the wireless power transmitting device. The power receiving unit wirelessly receives the power from the wireless power transmitting device after the communication unit transmits the location information.
