A device designed to validate and transport paper currency in a protected fashion. While being transported, the device monitors for tampering or break-in attempts and subsequently generates warning notifications, or sounds an alarm depending on configuration and the type of tampering detected. The transport case provides end-to-end cash accountability from a location where a bill is inserted into the case, to the bank or cash destination, where the transport case is delivered. Additionally, a docking station accessory is described in which the transport case can be securely fixed while at a point of sale.
