We manufacture an identification system. A frequent question we get is "How do we use this at our back gates which are for residents only?" Or "....which are for employees only."
In conversation on the phone or at trade shows its easy to explain, but I need something concise that encompasses both residents, employees, and all other authorized users to use in our brochure, website, and other marketing materials.
For a very concrete example we can say I'm working on a FAQ for our company's website. Saying "How can I use this at an authorized only entry?" Doesn't quite sound or convey the same message as "employees only" or "residents only." Is there a better option than Authorized Only which is concise and would include residential and commercial applications?
