Cash and cards

Cards work almost everywhere. Recent reports confirm the US is heavily card-reliant and increasingly cashless. Cards are accepted almost everywhere, from vending machines to taxis, making cash largely unnecessary. Contactless is widespread, though some retailers require physical cards.
