There are systems and methods for secure cashbox removal from a transit vehicle and emptying in a vault at a transit site. The cashbox is removably attached to a transit vehicle driven by a transit operator and can be taken to a vault to deposit the cash located in the cashbox. The cashbox has a cashbox tag configured to broadcast a cashbox tag present signal that is received within secure zones and alarm zones, and communicated to a monitoring system to ensure that no cashbox rules are violated in getting the cashbox to the vault for emptying.
