I'd like to know as well! From what I've read your post is accurate. My wife is in the process of setting up her own shop and will have a PDQ machine, this will undoubtedly accept payments via a NFC device (TBC!).
In regards to reduced transaction rates, I doubt this will be the case unless you can confirm otherwise? You're still handling a payment from a card issuer, be it the way that the card was presented to you was different.
