Who Issues the Mercury Credit Card

First Bank and Trust has extended its partnership with Mercury Financial multiple times over the years, reflecting a long standing relationship between the fintech company and its chartered banking partner.
First Bank and Trust, based in Brookings, South Dakota, is the chartered bank that extends credit and holds every account opened under the Mercury Visa Signature Card program, issuing the card pursuant to a license from Visa USA.
Mercury Financial itself is not a bank. Like many modern fintech card programs, Mercury partners with a chartered bank, First Bank and Trust, to legally issue credit while Mercury Financial manages the application process, technology, and customer experience.
What First Bank and Trust Does
Because First Bank and Trust handles the regulated banking functions, Mercury Financial can focus its resources on building consumer facing tools, credit education content, and a more approachable application process for its target audience.
First Bank and Trust provides the banking infrastructure, underwriting framework, and regulatory compliance backbone that allows Mercury to operate as a credit card program, while Mercury Financial manages the app, marketing, and day to day customer support.
This structure, sometimes called banking as a service, allows companies like Mercury Financial to launch credit products without becoming a bank themselves, relying instead on an established, chartered partner bank for the fully regulated portions of the overall business.
Mercury Credit Card Features
Cardholders should review the current cardholder agreement available on the Mercury Cards website for full details on fees, interest rates, and any specific account requirements before applying.
The Mercury Visa Signature Card is marketed as a credit building card for consumers with limited or less than perfect credit history, and it typically reports account activity each month to the three major consumer credit reporting bureaus.
Mercury also offers a business version of its card, the Mercury IO Card, which is issued by a different bank, Patriot Bank, N.A., pursuant to a license from Mastercard, and is aimed specifically at startups and small businesses rather than individual consumers building personal credit.
How Mercury Compares to Other Credit Building Cards
Newer fintech card programs like Mercury often emphasize a mobile first experience compared to older, more traditional credit building cards that may rely more heavily on paper statements and phone based customer service.
Mercury’s banking as a service model, powered by First Bank and Trust, differs from cards issued directly by a single bank, such as the Merrick Bank Credit Card, or cards marketed through established third party servicers like Atlanticus.
Consumers comparing Mercury against other credit building options should consider factors such as fee transparency, digital tools, and whether the newer fintech model or a more established issuer better fits their preferences.
Applying for the Mercury Credit Card
Prospective applicants can also read independent reviews of the Mercury Card program before applying, which can help clarify how the card compares to other credit building options currently available for similar consumers.
Applicants can review current terms and apply through the official Mercury Cards website, which lists fees, eligibility details, and account features directly from the company.
Because approval and starting credit limits depend on individual credit history, applicants should review the current cardholder agreement carefully before applying, since terms can be updated as the program evolves.
Because Mercury targets applicants working to build or improve their credit, understanding the full fee structure before applying is especially important for managing the account responsibly.
