Android pay can be activated when you are not rooted, and remains active if you root later. It is trivially easy to root/unroot flagship android devices and you have access to unblemished images from google if you happen to screw something up. My experience "hacking" my Nexus 5 to enable WiFi hotspots, without paying sprint for the service, required root, and the process took maybe five minutes.
