However，opinions vary from person to person. Some students think it important to be cashless because people can have a much easier and more comfortable life. Secondly，using the credit card or mobile phone to pay for goods instead of currency can reduce the cost of paper. However，others think very differently. It is easy for us to pay more than we can afford，so the cashless society is not a necessity. As far as I'm concerned，a cashless society has more advantages over disadvantages. Although there are risks and different voices，it is worthwhile saying yes to it.
