Non-cash payment is the best way to go. I pay for everything with my smartphone. It only takes a blink of the eye — just scan the barcode and click! And I never have to carry lots of heavy coins or dirty notes, or worry about losing my wallet — for the fourth time! Speaking of “dirty”, do you know that there are more germs on a coin than on a toilet seat !

It might not be safe as you think, as computers and phones can be stolen or hacked easily. I also worry about over-consumption. If I have $20 in my purse, I can only spend up to that amount. But with electronic payments, I can spend again and again, just as long as my bank account has money in it! And what if you’re in a place without Internet access or your phone battery dies

I agree that there are problems in electronic payments. Despite their convenience, people who don’t know how to use electronic payments might feel excluded, especially the elderly. Perhaps we could talk about using money less often, rather than replacing it for good
Definition of non-cash payments
Benefits
No cash is involved when people are making their payments. People make their payments with cards, mobile phones and other electronic devices.
Convenient and fast. Do not need to carry lots of heavy coins or dirty notes. No more worries about losing wallets.
Problems
Conclusion
Not safe enough and may lead to over-consumption. Some forms of electronic payments are restricted to the Internet. Potential inconvenience exists if the phone battery dies. Some forms are unfriendly to those who don’t know how to use electronic payments, especially the elderly.
Non-cash payments, or electronic payments, bring us a lot of advantages. However, the disadvantages can’t be ignored. Maybe we could try to use money less often, rather than replacing it with non-cash payments for ever. Meanwhile, we need to think of ways to make non-cash payments better, friendlier and more scientific.

Sample:
Nowadays, non-cash payments are becoming more and more popular across the world, especially in China. It refers to the method of making payments with cards, mobile phones and other electronic devices. New ways of supporting non-cash payments are quickly turning up one after another.
Obviously, there are many benefits of non-cash payments. First, they are so convenient and fast that people could make almost all the payments with a single click on their smartphones. In some shopping centres, they can pay by simply standing in front of a camera and let it recognise their face. Second, non-cash payments are safe and hygienic. They free people from carrying heavy coins and dirty notes, or even a wallet. Therefore, the risk of losing money or the wallet is not a threat any more. What is more, non-cash payments eliminate the risk of counterfeit money.
However, as the old saying goes, every coin has two sides, and so does the non-cash payments, even though they don’t require a coin. The problems that accompany non-cash payments should not be ignored. When thinking it further, non-cash payments might not be quite safe as people have assumed, as it is not that hard for hackers to access people’s bank account and steal the money. It is also easier for your personal information to be stolen, which may bring great trouble. Meanwhile, to some degree, non-cash payments encourage over-consumption. They also depend too much on the Internet access or battery capacity — just imagine being at a place with no wi-fi and a flat battery, how can people make payments via their computers or smartphones then Last but not least, non-cash payments aren’t quite friendly with people not knowing how, especially the elderly. It is such a pity to make them feel excluded and left out.
Nonetheless, non-cash payments are increasingly part of our fast-growing modern society. The current trend is for more non-cash payments, and this trend will probably continue in the future. But embracing a new trend doesn’t mean to exclude the “old-fashioned”ways. Perhaps it is more convenient for everyone-young and old, men and women-to have various options, in both cash and non-cash forms, when it comes to making payments, for the better good.
