I think you may be asking the wrong question. A police officer can ask you to do anything they want. Its up to you to ask a question back (or conditionally accept) ie.
Officer: "Show me some "ID".
you: "May I see some Identification?" (they are required to by their own law)
Officer: "This car/badge/uniform is identification anough."
you: "Are you refusing to Identify yourself?"
and so on?

A police officer can ask for anything, for any reason or no reason at all. He can demand to see your identification only if he has appropriate grounds, which are too varied to list here.
If a police officer asks you for your identification and you aren't inclined to provide it, you can ask (politely), "May I ask why you want to see my identification?" If you aren't satisfied with the answer, ask "Am I free to leave?" If he answers anything but "yes," you are being detained, which requires at least reasonable suspicion of wrongdoing.
If you are a police officer you would not need to ask. A police officer doing his duty will treat another police officer as any member of the public (if they are out of uniform and off duty).
A police officer should show his badge when he approaches you. If the badge is not visible, ask to see it. If you ask for the badge number, the officer should give it to you. If the officer refuses, you should report it to the police department.
