Fidelity National Information Services is the world's largest provider of banking technology - its core banking systems process transactions for 20,000+ financial institutions globally. Its Worldpay acquisition made it a major payment processor before being divested. Every time you use an ATM, make a wire transfer, or check your bank balance, there's a good chance FIS technology is processing it.
