Abstract
An example apparatus for allowing operation of equipment by an authorized operator comprises a biometric scanner receiving a biometric input from an authorized operator, and transmitting an authorization signal. The apparatus may further includes a base station that allows the equipment to operate while the base station receives the authorization signal from the biometric scanner, and which prevents the equipment from operating shortly after the authorization signal is no longer received from the biometric scanner.
