When I worked at the Federal Reserve, our vault was managed by autonomous, self-driving vehicles (more robots than trucks - basically smart forklifts). They drove standardized boxes of money around from counting rooms where humans touched the money, to storage where humans were not allowed to go. Warehouse management software knew exactly how much money was in each box. Laser scanning was used for guidance and security.<p>This was over a decade ago. I&#x27;m sure things are much better now.
