【妙笔成篇】
Non cash payments are becoming increasingly popular, with fewer and fewer people using cash.
Non cash payment brings us a lot of benefits. Firstly, it saves people's time to pay bills. Second, people don't have to worry about getting the fake cash. However, mobile payment systems are prone to fraud. If the users' personal and financial information falls into the possession of fraudsters, then they can defraud the users of their money.
Therefore, high security risk is the key factor users should take into consideration when making mobile payments. They should carefully protect their payment accounts and passwords.
