Should I worry about nox if I want Samsung pay?

Really want to root and install a custom rom but Samsung pay looks cool, I have heard if nox is tripped this won't work. Does this mean devs will work round nox to get Samsung pay working on tripped devices, or will I be screwed ?

Also android pay, is that available for all android devices and if so could I use that instead? Any help would be great.

Thanks :)
