Such a requirement could diminish credit card profit margins, leading to stricter lending requirements as well as reductions in the number of points rewarded for purchases made with co-branded cards. 
Other possibilities include higher annual fees and less generous sign-up offers for co-branded cards, said John Kiernan, managing editor of personal finance company Wallet Hub.
Co-branded cards aimed at higher-risk consumers would likely take the biggest hit.

The ConfirmID is good for 10 days once payment has been made.
Real ID requirements took effect last May, and the TSA said 94% of travelers who pass through airport screening use either a state-issued Real ID drivers license or another acceptable form of identification such as a passport, passport card or DHS trusted-traveler card like Global Entry.

The TSA said the new ConfirmID fee will ensure that noncompliant travelers shoulder the cost of that extra screening, rather than taxpayers. 

Blatter was the latest international soccer figure to call into question the suitability of the United States as a host country. He called for the boycott in a post on X that supported Mark Pieths comments in an interview last week with the Swiss newspaper Der Bund.
Pieth, a Swiss attorney specializing in white-collar crime and an anti-corruption expert, chaired the Independent Governance Committees oversight of FIFA reform a decade ago. Blatter was president of the worlds governing body for soccer from 1998-2015; he resigned amid an investigation into corruption.
In his interview with Der Bund, Pieth said, "If we consider everything weve discussed, theres only one piece of advice for fans: Stay away from the USA! Youll see it better on TV anyway. And upon arrival, fans should expect that if they dont please the officials, theyll be put straight on the next flight home. If theyre lucky."
