Depending on your method, yes.

Most devices read the contents of the ring and then remember those credentials rather than reprogram the ring themselves.
So as long as you program your own data into the ring and then don't change it, you should be good to go. Just program each access control device after that to recognise what you have entered into the ring.

hands me the decive to enter my PIN.

Would be great to avoid giving away the PIN to anyone looking. Or if the hardware is cloning. There may have been a bluetooth-based ring up for pre-order (Kickstarter?) with a display, which could solve some of this. But generally just pre-approving myself with a budget for coffee-places, another for lunches, etc would allow payments without PIN in these places.
