I think we can say:
Technology XY doesn't work with batteries, does it?
to ask the other person for confirmation / to ask if you're correct or not.
But how to do the same with a sentence with cannot:
This device cannot communicate with the protocol Y, can it?
Is this ending "can it" correct? I rarely here it.
Meaning I'm looking for: "it cannot communicate with ..., please correct me if I'm wrong"
