Another prerequisite for effective cash defacement, is that the process must be unstoppable, once activated. We need to make sure the custodians are unable to influence the cash defacement process, so they will not be exposed to violence that is intended to force them into stopping the defacement. After all, it is out of their control.
Draw attention to an attack
In case of an activation, a siren will be audible. Optionally, the High Energy defacement module can be fitted with a crime scene marker. Together with the siren, this will frustrate the criminal by attracting unwanted attention to the crime scene. Frustration is the main reason why a MactwinBox is practically always left behind at the crime scene.
The crime scene marker will also add an orange coloring to the cash, which is still mandatory in some countries.
