Fiserv

About Fiserv

Fiserv is a U.S.-based financial technology and payments company that provides core account processing, digital banking, payments, merchant acquiring, card, and commerce infrastructure for banks, credit unions, merchants, fintechs, and large financial institutions. In the 21Rates directory it is tracked as core banking and payments infrastructure rather than a direct consumer Bitcoin access provider. Fiserv previously partnered with NYDIG to enable banks and credit unions to offer Bitcoin buy, sell, and hold access through their existing banking systems, but that rail became stale after NYDIG exited the credit union and community bank Bitcoin business.
