Vending machines often stand unattended. Security protects the products, the cash, and the machine.
Vending machines are protected on several levels: a lock on the main door, a separately locked cash box, a door-open sensor, and – on connected machines – alerts about unusual events. Placement matters too: visible, well lit, and monitored where possible.
Locks
The door has a mechanical or electronic lock. The cash box often has its own key, so the person restocking products cannot access the money.
Sensors and alerts
A door sensor logs the event in the controller. Telemetry can alert the operator, for example when the door opens outside the schedule.
Placement matters
A machine in a visible, lit spot is less exposed to damage. The page on places for vending machines (publisher's site) gives placement tips.
FAQ
Are cashless machines safer? No cash removes one risk, but the machine and products still need protection.
Who has the keys? Usually the operator and their service staff, per internal rules.
