FIS

Banks and merchants often rely on financial technology that customers rarely see, and FIS is best known for supplying that infrastructure. Its business spans payment processing, banking software and services that help financial institutions run accounts and transactions. That makes it a business-to-business company rather than a consumer bank with a familiar branch or checking account. By our assessment, its strength is the breadth of tools it provides across banking and payments, which can make it a significant part of how other financial companies operate. The trade-off is that the services are complex and largely indirect: the experience depends on the bank or merchant using them, not on a single FIS app. It belongs among major financial technology providers, alongside firms that sell core banking and payment systems. Its role is clearest in the transactions and software that customers encounter under another company’s name.
