The law says that all businesses in the United States must accept American currency, but that simply means that it would be illegal for a company to require payment in Pesos or Euros. The law also says that paper dollars and coins are recognized by the government as American currency. From these two laws, many people wrongly assume that businesses have to accept paper money or coins...but the law doesn't actually say that.

The law requires that American businesses accept American currency, but it doesn't actually specify any particular form of that currency. They can require credit cards only, checks only, cashiers checks only, wire transfers, etc. The only limitation is that they MUST accept amounts specified in American dollars.

Legal: "We only take checks"
Illegal: "We only take pesos"
Legal: "We don't take cash payments over $50"
Illegal: "We take cash, but not American cash"
Legal: "We only accept credit cards, and will charge you $10 for this service"
Illegal: "We only accept credit cards, and will charge you €10 for this service"
