I never wear my rings places where I don’t also bring my fingers, and rings don’t leave oily prints like my fingers do. Sarcasm aside, I’m not sure how this is a security risk.
In 2014[0], someone stole the German Defense Minister's fingerprint from a picture. We are well past the point where you can assume your biometrics are secure.
I guess you can go ahead and take "criminal mastermind" from your CV! Why would I think that a physical 3D object with the pattern of my fingerprint that can be carried around and held up to anything might possibly be a security issue? Nope, I can't think of anything...

Careful, your sarcasm is dripping!

Have you looked at the image of the ring? How do you plan to scan that anywhere?
