When staff make a vehicle booking they are given a unique booking number. When it comes time to depart, they enter that booking number into the touch screen. For take-home cars, staff use their Employee ID and a recurring nightly booking.
KeyMaster then validates the booking number and guides the driver through the Check Out process. One such prompt is to ask the driver if they still hold a valid drivers licence.
The driver is asked to open the door and the slot containing the key which corresponds to their booking lights up. The locking pin is released and the driver removes the key. Whilst this happens, the integrated camera takes a photograph of the driver for audit purposes.
