So, you’re trying to pay for either UberX or UberEats. Do they take cash or card?
Do You Pay Uber With Cash or Card?
Sorry to make you sad. Uber does not take cash. Since cash is hard to track financially, Uber does not allow payments in this way. They only accept debit or credit card.
Feel free to tip driver in cash, however. Tipping in cash means this cash is not reported when doing taxes at the end of the year. This is a big deal for drivers. They will thank you.
