1. A method of regulating access to an asset in an access control system, the method comprising:
establishing a first wireless connection with a key-device using a low power communication protocol;
receiving a credential for a user of the key device over the first wireless connection;
establishing a second wireless connection with the key-device using Ultra-Wideband (UWB);
determining the user intends to access the asset, wherein determining the user intends to access the asset comprises determining the user meets a first intent threshold based on the second wireless connection; and
permitting access to the asset in response to determining the user intends to access the asset and determining the user meets a second intent threshold based on the second wireless connection.
