It's basically a collection of API standards for common messages to and between financial institutions. If you need to communicate a lot with your bank or banks generally, then you'll probably automate it through this standard, at least in Europe, I'm not sure about adoption elsewhere. Things like reading accounts, registering transactions, stuff like that. You can, for example, build a background job that does monthly consolidation of accounts against a pile of payment providers your customers use.
