AI Overview                 
When a private business refuses to take cash, nothing illegal happens at the federal level in the United States. Private stores and restaurants can legally choose what payment types they accept, unless specific state or local laws say otherwise.

Some states and cities ban cashless businesses to protect people without credit cards or bank accounts (learn more via Stateline). Places like New York City, New Jersey, and Massachusetts have rules requiring cash acceptance in many retail stores.

Potential Drawbacks for the Business

Lost Customers: People who rely only on cash or do not want to use digital payments will shop elsewhere.
Processing Fees: The business must pay transaction fees to credit card companies on every single sale.
Outages: If the internet or payment network goes down, the store cannot process any sales at all.
