Abstract
An authentication module may be internally or externally installed on a lift control of a vehicle lift and allows new and updated features to be added to the vehicle lift without requiring a connection to a local or cellular network. The authentication module connects to one or more other electrical components of the lift control to allow for the exchange of data. A module containing software and configurations for enabling a feature may be removably attached to the authentication module, which uses the stored configurations to verify and enable the associated feature. The use of enabled features may be persistently tracked by the authentication module even in the absence of an external power source or network connection, and may be disabled by the authentication module if the feature use expires or is exhausted.
