PURPOSE: A safety management system of a smart phone showcase is provided to prevent customers from bringing smart phones when a store is crowded. CONSTITUTION: A power part (21) supplies power. Multiple tags (10) are attached to smart phones (1-N) arranged in the showcase of a store and transmit wireless signals with specific ID when receiving the power from the power part. A receiving part (22) receives the wireless signals with the specific ID transmitted from the tags. A control part determines whether or not the smart phones are deviated by analyzing the strength of the received wireless signals. If the smart phones are deviated, the control part outputs burglar warning signals. An indication part (28) is composed of an alarm or LEDs to inform the deviation of the smart phones from a predetermined range.
