An example display unit for facilitating operation of equipment includes a housing, an electronic display supported by the housing, and an electronic circuit located within the housing. The display unit may include one or more data receivers, such as a wireless receiver and/or an electrical interface. A biometric scanner, including a biometric sensor and proving an authorization signal when an authorized biometric input is detected by the biometric sensor, may be configured to electrically (and optionally mechanically) interconnect to the display unit. The example display unit receives an authorization status for operation of the equipment from the biometric scanner, and displays the authorization status and operational parameters relating to equipment use on the electronic display.
