Xiamen supermarket code scanning gun _ talk about the embarrassing things I have encountered when scanning code payment

It is also an actual experience. Through my own WeChat or Alipay shopping payment, I paid a sum of 17 yuan less, a sum of 7 yuan, a sum of 12.5 yuan, etc., which adds up to more than 40 yuan. After deducting the money I have returned, the amount I did not actually pay is more than 20 yuan.

It ’s not that I did n’t pay, I did n’t scan the code, it was because the fingerprint password was used when scanning and paying. Sometimes, the speed card fails to pay if you are not careful. The other one, I do n’t know if you have found that the average young person pays in this way. After entering the money, they have already gone outside while paying. This kind of payment is easy to fail, and, even if the person who can't find the payment, even if it is encountered next time, others will not necessarily remember this matter, this problem is very common.
