Description

Smart management and monitoring method for a refrigerator, and a wearable device and tag device used therein The present disclosure relates to a smart management and monitoring method, and more specifically, to a smart management and monitoring method for a refrigerator, and a wearable device and a tag device used therein. Human body communication is a technology that transmits data using the human body as a communication channel, allowing various devices located close to the human body to transmit and receive data through it. When a fixed communication device attached to an object and a user's mobile communication device transmit and receive data via human body communication, a situation may arise where mobile communication devices belonging to other users who are near or in contact with the user receive data from the fixed communication device. In particular, a home appliance may be one of the fixed communication devices, and a mobile communication device worn by a user may communicate with the home appliance to facilitate the user's use of the home appliance and receive and provide information or data regarding the use of the home appliance. According to this, human body communication provides more efficient and advanced convenience in using home appliances, and related research is actively underway.
