Reasons for abnormal payment:

1. Insufficient account balance. Once the amount of the background deduction account is lower than the cigarette money, the payment will fail and the order will be cancelled. Therefore, it is best for everyone to form the good habit of saving 1~5 yuan more when saving cigarettes every day.

2. The quota problem. The card limit bound by the background deduction limit is not limited if it is a credit card or a first-class debit card; Class II and III debit cards have a limit. At present, it has been found that debit cards of postal savings and rural credit cooperatives are restricted because they are two or three types of cards.

3. It is best to confirm with the bank whether the card with background deduction is a first-class card or a second-class card. If it is a second-class card, it is best to apply to the bank to change it into a first-class card.

abnormal bank card account. This kind of problem is rare. The common situation is that the reserved mobile phone number has been stopped, the card's valid life has expired, and the password has been frozen many times because of wrong input. The solution is to go to the bank to handle the relevant settlement procedures.

In addition, inter-bank payment is limited by the amount of UnionPay. For example, the amount of inter-bank deduction for the savings card of Agricultural Bank of China is 5,. If it is a credit card, it depends on whether the card level has a fixed value (specifically ask the bank). This is the online payment limit set by the bank, which has nothing to do with the card balance or credit card limit. If the order amount increases, it is recommended to change the card.
