（11.11特供）Mobile Payment VS Cash：Are We Creating A One day a year ago I accidentally left my wallet in home and went out. All I found in my bag were keys and mobile phone. At that moment I thought :“Oh my god I'm screwed，what should I do ?”But Then I ride a mobike to a near shopping mall ,bought a beautiful skirt . Obviously, cash is falling out of fashion. So will it disappear forever? I guess not. Cash may become less popular, but it will remain with us forever. Why?
