A franking machine, comprising:

• a controller including a program memory;
• a security module;
• a first communication interface that is configured to implement one or more security measures to, in cooperation with the security module, securely communicate with a remote server to prevent harmful code from being transmitted to the controller or prevent an operational security of the goods processing apparatus from being affected, the security module and the first communication interface are electrically connected with the controller;
• an acoustic output device electrically connected with the controller and configured to output audio files or sound files, the acoustic output device including a speaker;
• and
• a housing configured to house the controller, the security module, the first communication interface, and the acoustic output device, the housing including an opening, wherein the speaker is mounted to cooperate with the opening such that a membrane of the mounted speaker is configured to emit sound waves outward through the opening,
• wherein the program memory stores a program to control the acoustic output via the acoustic output device, the program being configured to facilitate, using the one or more security measures, external commands being securely transmitted from the remote server, or from one or more other internet sources, to the controller.
