It is for use in chemists - I will put your suggestions to client and see what they say - It doesn't talk however. I think you may need an access code to use it and that it is only for potentially infectious waste - I appreciate your answers and help.

not necessarily.... interactive or intelligent. GPRS just means it's connected to the mobile phone network, so if it contains a weighing device, for example, it might send a message saying "empty me!". I'm at a loss to understand how (barring Disney, for whom all things are possible....) a waste disposal unit could be interactive, unless "ouch!" counts. Why complicate the issue? What's wrong with "communicating terminal"?
