As an exchange student, I have lived in China over the years. China a lot in the years since I first moved here. One major development has been the wide use of cashless payment(无现金支付).China is hardly the first country to have cashless payment. I . a debit card(借记卡)to pay for things without cash for years in the US. But now I use my phone here instead, it's very easy and convenient. One of the things I like most is that I can send and receive money directly among my friends. Cashless payment makes it so much easier the bill when we eat out together. And I can make donations simply as well. For example, I often give away money to Animal Helpers by using its QR code(二维码).

    But cashless payment has some problems as well. What will happen if your phone ? There are also times when your phone's mobile internet connection might not work. So even though cashless payments are convenient, I a bit of cash with me in order not to meet any possible trouble.
