When you pay by credit card, first you will receive a debit message, then you will receive a correction message. What does that mean? Is it buckled or not?

Generally speaking, there are three main transaction states of credit card payment: success, failure and uncertainty.

In banking, hedging is the reverse of active trading. The business and technical understanding of this term is different. Technically, UnionPay transactions are often used, such as withdrawing money. When the transaction is incorrect due to overtime or other reasons, it is necessary to send a reversal transaction to the original withdrawal to prevent the transaction from failing, but the customer account is re-recorded. In business, the original accountant called it every other day, that is, the original account charges in the same direction.

Unilateral deduction means that you used your credit card to spend money, and the bank deducted money successfully, but the merchant did not receive the money, and the bank will correct it for you, that is, return your money, and then you need to use your credit card again until it is successful.
