Reader coordination for access control

An access control system comprising:

• a first access facility;
• a second access facility;
• a first reader configured to control access through the first access facility, receive a credential using a first communication protocol from a device that stores the credential, and establish a secret with the device using the credential;
• and
• a second reader configured to control access through the second access facility, wherein the first reader is configured to provide the secret to the second reader, and wherein the second reader is further configured to perform ranging using the secret and a second communication protocol different than the first communication protocol to identify intent information;
• wherein access through one of the first access facility or the second access facility is coordinated using the intent information.

A method for providing access control, the method comprising:

• receiving a credential by a first reader associated with a first access facility using a first communication protocol from a device that stores the credential;
• establishing a secret with the device using the credential;
• providing the secret from the first reader to a plurality of second readers associated with respective second access facilities;
• identifying intent information for the device by performing ranging by the first reader and the plurality of second readers using the secret and a second communication protocol different than the first communication protocol;
• and
• coordinating access through the first access facility and the respective access facilities using the intent information.
