How many countries is FIS in?

Could you please clarify for me the exact context of "FIS" that you're referring to? As there are multiple organizations and entities that use this acronym, I'd like to ensure that I'm addressing the correct one. However, assuming you're asking about a financial institution or service that operates globally, the number of countries in which it operates can vary greatly depending on its reach and scope. Some may operate in just a handful of countries, while others have a global presence spanning dozens or even hundreds of nations. Without more specific information, it's difficult to provide an exact number. Could you provide more details or context about the "FIS" you're inquiring about?
