One-time access for electronic locking devices
摘要:
Systems and methods for providing one-time access to electronic locking devices for non-keyholders. The one-time access rights are delivered from a server to the electronic locking device in real-time, or in near-real time, over short and long-range wireless communication links in a manner that is secure and traceable. A handheld device is coupled with the electronic locking device via the short-range communication link, and is coupled with the server via a long-range wireless communication link.
