Systems and methods for electronic access control for secured assets including locked facilities, lockers, shared vehicles and vending machines, which do not have internet connectivity. A mobile device communicates with a server to perform the authentication and access control steps, limiting the asset's interactions with outside devices to exchanging and updating access codes via short-range communications, such as near-field communications. Authentication and access control steps may be performed when the mobile device is at the secured asset, or alternatively those steps may be performed in advance, to allow access to assets located outside of data service to the mobile device. |
