A method according to one embodiment includes receiving, by an access control device, a credential token from a mobile device, wherein the credential token includes an access credential, a credential identifier, and a caveat that instructs the access control device to perform an associated action, determining, by the access control device, a credential type associated with the access credential based on the credential identifier, determining, by the access control device, a set of caveat rules associated with the credential type, wherein the set of caveat rules identifies one or more actions authorized for an access credential of the credential type, and performing, by the access control device, the associated action identified by the caveat in response to a determination that the associated action is an action authorized by the set of caveat rules associated with the credential type.

Utilizing caveats for wireless credential access

An access control system and methods according to at least one embodiment leverage wireless access credentials to allow a user to securely gain access to a secured area using his or her mobile device. As such, a credentialed mobile device may permit access to the secured area without requiring a real-time connection to a credential management system and/or an administrative system.

Wireless access credential system

A method according to one embodiment includes determining, by a host processor of a master device, a combined cost of an outgoing message transmission of the master device and an expected response message from a slave device; determining, by the host processor, a number of available tokens associated with data transmission; reducing, by the host processor, the number of available tokens by the combined cost in response to a determination that the combined cost does not exceed the number of available tokens; periodically increasing the number of available tokens up to a token maximum by a predefined number of tokens based on a token refill rate; and sending the outgoing message from the host processor to Bluetooth Low Energy communication circuitry of the master device in response to the determination that the combined cost does not exceed the number of available tokens.
