【答案解析】[范文] Paying with phone—no substitute for cash
As is illustrated in the picture, the woman is intended to pay with her phone, but the cashier told her that the last person paid $1m accidentally with his phone. Seemingly funny, the picture reveals that when we are enjoying the convenience brought by paying with phone, it also causes some severe problems.
First, since each payment is traceable, people hate the idea that their transactions are monitored and tracked. Second, the security of accounts is another big issue. Hackers may decode the key of bank accounts and incur huge losses of both banks and individuals. That Google temporarily shut down its wallet system due to a security vulnerability is a good illustration of the possibility of accounts being hacked by immoral users. In addition, average citizens have little control over how the database that stores all the personal information would work and they are deeply concerned that their private information may be illegally given out or sold to others.
In conclusion, when enjoying the convenience of paying with phone, people should not lose sight of the accompanied risks. Before a sound system of electronic transactions can be invented, paying with phone is still no substitute for cash.
