SUhide does exactly what you would think it does. It hides Super User from apps that would block you from use like Android Pay. The mod for SuperSU is experimental. It selectively hides root from applications. It can also hide root on a per app basis so you don't need to unroot your phone. You don't need to have xposed framework to install the mod. This won't last long.
To install this you will need to flash the suhide.zip followed by the supersu.zip. If you do not reflash the supersu.zip you will encounter bootloops. To blacklist an app you need its UID. The UID for an app can be tricky to find. You will also need to execute a few commands. This is not for the untrained. Head to the link below for full details.
