【Conversation one】
M: Lisa, why did you pay for your meal with cash instead of the payment apps on your phone?
W: Well, I’ve gone back to cash. I’m only using payment apps if that’s the only option. [8]I am trying to save money for a new phone. And I find that using cash rather than payment apps helps me to save. M: But how? Money is money, isn’t it? I don’t think it matters whether you take it out of the bank and put it in your wallet will simply transfer from your bank account to the seller’s bank account using an app.四级听力
W: No, I believe it does matter. It’s a psychological phenomenon. [9] I believe we have less connection with the value of our money when we just have the approved buttons on our phones.
M: You might have a point. Since I stopped carrying cash around and started using my phone apps to pay, [10] I may have developed a tendency to buy more small or nonessential items.
W: That’s highly possible. Think about the amount of time we spend with our phones in our hands and all the things we do with our phones. It sometimes seems that our phone is buying the product for us, not ourselves.
M: [11] So cashless payment affects our ability to budget？
W: I believe so. If we spend a hundred yuan in cash, we realize that we don’t have that hundred yuan to spend on something else. But if we’re spending electronically, we are less likely to make that mental calculation.
M: I stopped using my credit card because I found out spending excessively, perhaps I should take the same approach of paying using my phone.
W: It’s worth considering.
