What moment made you feel that mobile payment really changed your life?

Mobile payment promotes the security of the financial market, promotes the economy and is more convenient for human beings. My personal experience is that once there was no coin on the bus, mobile payment appeared at this moment, and the embarrassing moment in front of me was solved by scanning the code. In the past, people were particularly cautious about money, fearing that they would be penniless if they neglected it. But now, no matter what means of transportation you take, you don't have to worry about losing money, you can rest boldly! So mobile is everywhere, changing human life all the time, affecting generation after generation and bringing convenience to countless people!
