It's so tough to pay cash in China that the government had to fine a KFC for not accepting banknotes

• China recently fined several businesses, including a KFC, for refusing to accept cash.
• These are some of the most established companies in China, showing just how quickly cash has fallen from favor there.
• It's a problem for a China hoping to attract foreign tourists who aren't part of the cashless system.

China's central bank fined seven businesses last week — including a KFC and branches of state-owned corporations — for rejecting cash payments, all as Beijing pushes to make spending more accessible for foreign tourists.
