suhide hides systemless SuperSU from various apps - including Android Pay (for now, anyway).
It currently only hides the su binary, not the SuperSU GUI, but this is enough to fool many apps.
There's no user interface at this time, you have to blacklist uid's by hand. Maybe there will be in the future, maybe not. Maybe it will be integrated into SuperSU itself, maybe not. It all depends.
Read more in the thread linked below. Note that this is not an officially supported app or part of SuperSU. If it breaks you get to keep all the pieces.
