Vending Machines (VMs) employ a series of physical locks to prevent unauthorized access and/or control of the machine. In addition to the lock on the front door, in one embodiment of the invention an electrical door switch is employed that is used to enable a set of protected commands to the Vending Machine Controller Card (VMCC) only when the door has been opened. An electronic override of this switch, via remote control of a telemetry device (VIU) coupled to the VM, allows the VMCC to accept protected-mode commands from a central command server via a wireless network regardless of whether the door was actually opened. Other embodiments are described herein. |
