It should continue working.

No. The terminal should be able to power the chip the same way.
I don't have one, but that's how I understand it works.

Having a user interface ought to help, if only for configuring it. You should also be able to get a history of transaction.
One of the aims is to support things like loyalty schemes, which would presumably involve some UI. For example, I currently use a pre-paid bus card, which I could get rid of if my phone did the job.
All of that said, personally I think RFD belongs in a wristwatch or a ring rather than a phone. Preferably the watch, so it can have a bit of UI there too. (Specifically I'd want it to vibrate for every transaction, even small ones, and to vibrate if it gets too far away from my phone, and unlock my phone automatically when it is held in my hand.)
