Dear Tom,QtK答案圈

How are you? Glad to tell you something about mobile payment in China.QtK答案圈

Mobile payment is very popular in China. It has made people?s daily life more and more convenient. Most of us are used to paying by scanning QR codes.QtK答案圈

By mobile payment, we can pay easily wherever we go. You can buy breakfast on the street and pay by scanning with your smart phone. In the subway station, you scan with your smart phone to purchase your ticket. This is a glimpse into the life of most Chinese - allowing us to bid farewell to the wallet and bank cards.QtK答案圈

Mobile payment has greatly changed people?s lives in China. It seems that China is really leading in some ways and is also sweeping other nations.QtK答案圈
