You are not required to carry ID unless you're driving a car. Unless pulled over for a traffic offense, there is no legal requirement to show your ID.
NRS 171.123 requires you to "identify yourself". The Nevada Supreme Court interpreted "Identify Yourself" as meaning stating your name only. You need not provide your address, date of birth, social security number, or any other piece of information. Just your name verbally meets the legal requirement.
Also, that law requires LEO to have reasonable and articulable suspicion (a Terry stop) of a crime. If LEO does not has RAS, you're under no obligation to even state your name.
