A goods processing apparatus includes a controller including a program memory, a security module, a first communication interface that is configured to, in cooperation with the security module, securely communicate with a remote server, and an acoustic output device electrically connected with the controller and configured to output audio files or sound files. The security module and the first communication interface can be electrically connected with the controller. The program memory may store a program to control the acoustic output via the acoustic output device. The program can facilitate external commands being transmitted from the remote server, or from one or more other internet sources, to the controller. Via security measures, operational security of the goods processing apparatus is prevented from being negatively affected, or harmful code is prevented from being transmitted to controller.
