It says 67% of users used WeChat to make payments of atleast 100RMB a month. That's a significant number! I guess WeChat makes a commission on that payment. Would that be the largest moneymaking feature of WeChat?
Is it really that weird? My wife uses weixin for normal things like buying lunch, paying for a taxi, buying veggies at the stand downstairs. It would add up to more than 100 rmb/ month, but then so would a UnionPay card, and Tencent is subsidizing the heck out of this right now to get adoption up.
QR is a lot less convenient than RF, ApplePay this is not.
