Abstract: Disclosed herein are an apparatus and method for managing personal information.

Abstract: A method and an apparatus for providing a service using a kiosk by a service providing server by performing the steps of: receiving a device list of at least one kiosk having an ability to provide the service among a plurality of kiosks registered in a blockchain from a kiosk server; authenticating a first kiosk through a smart contract function embedded in the blockchain when a user requests the service through the first kiosk and determining whether the first kiosk is included in the device list; and providing the service to the user when the first kiosk is authenticated by the smart contract function and is included in the device list are provided.

Abstract: A wireless power transmitter performs a method for supplying power for wireless charging from the wireless power transmitter to a plurality of wireless power receivers. The wireless charging method includes allocating priorities to one or more electronic devices that connect for wireless charging, and supplying wireless power to the one or more electronic devices based on the priorities. Other embodiments may be implemented.
