▣About FIS

FIS, formally Fidelity National Information Services, is a U.S.-based financial technology company providing banking, payments, capital markets, risk, lending, and core processing infrastructure to banks, credit unions, asset managers, merchants, and other financial institutions. In the 21Rates directory it is tracked as core banking infrastructure rather than a direct consumer Bitcoin access provider. Its public crypto and blockchain activity is institutional and infrastructure-oriented, including digital asset and blockchain-enabled financial-market rails, rather than a confirmed live retail Bitcoin buy, sell, or custody integration for credit unions.
