Abstract: A device for notifying a manager terminal of an event occurring in a coffee making device and an operating method thereof according to the present invention may enable a manager to visit an unmanned coffee shop only when a coffee making device needs to be managed and manage the coffee making device by determining that a first inventory shortage event for first inventory occurs when first inventory among the materials included in inventory data received from the coffee making device making coffee corresponding to each of the coffee menu items is larger than a first threshold inventory value and is equal to or less than a second threshold inventory value among threshold inventory values for the first inventory, determining that a second inventory shortage event for the first material occurs when the first inventory is equal to or less than the first threshold inventory value, transmitting an event occurrence message for the first inventory shortage event to a first manager terminal of a first manager who is a m

Abstract: Disclosed are a coffee drink order processing apparatus using an unmanned coffee drink making machine and an operating method thereof. The present invention may provide support so that, when an order request message for a coffee drink is received from a client terminal of a user, a making-reservation command for the coffee drink ordered by the user is transmitted to the unmanned coffee drink making machine installed in an unmanned coffee drink selling store in consideration of an expected arrival time of the user at the unmanned coffee drink selling store, and thus the user may immediately pick up the coffee drink that the user ordered without a waiting time when the user arrives at the unmanned coffee drink selling store.

Abstract: Disclosed are a device enabling coffee preparing apparatus to provide user with ordered coffee and method for operating same, which may enable the coffee preparing apparatus to block a user other than an orderer from picking up the prepared coffee and provide the prepared coffee to the orderer by generating identification information matched to a coffee order requested from each of user terminals to enable picking-up of the coffee corresponding to the coffee order, transmitting the identification information matched to the coffee order requested from each of the user terminals to each of the user terminals, transmitting an identification information input request message to a user terminal requesting a coffee order corresponding to a coffee preparation completion message from the coffee preparing apparatus, comparing identification input from a user of the user terminal in response to the identification information input request message with identification information transmitted to the user terminal, and req
