KEY INFORMATION MANAGING METHOD, UNLOCKING SUPPORTING METHOD, KEY INFORMATION MANAGING SYSTEM, AND UNLOCKING SUPPORTING SYSTEM

摘要

In response to a request of an affiliated store device (200), a key information managing server (110) correlates key information necessary for unlocking with information specifying the user of the key and registers the key information in a key information database (120). When an affiliate store device (200) requests the key information managing server (110) to output the registered key information through a network (320), the server (110) searches the key information database (120) according to the information specifying the user and outputs the retrieved key information to the affiliated store device (200). The affiliated store device (200) allows a display (240) to display the key information. Thus the lock can be unlocked quickly at low cost without breaking it.
