Where it works
Everywhere. This is bookkeeping rather than a rail, so it behaves identically whichever market your money is in and there is no coverage map to check. If you can use it at all, you can use it in every country you operate in.
What people use it for
The jobs that need this capability. Most need more than one.
Building with it
