There are certain strategies operators can employ to increase the security of their notes in the process of having them transported by a third party.
Dispenser's Cash Box
For dispensers, we recommend acquiring a second copy of each cash-box. With these, an operator may restrict access to any party in charge of refilling the machine's funds. With the additional cash box, the changing party would need not access to the inside of either box, but could rather be provided with a full box to swap out for an empty or low one.
Validator's Cash Box
A second upper cash-box, as well as a cam-lock for each, would apply the same security mentioned above, but to the validator's funds.
Newly shipped machines come with a small blue bag, containing metal mounting brackets, attached to the side of the upper cash box, these are used to hold a cam lock in place at the hole located near the top of the cash box door.
