In particular, the card number must be compared before filling in. Otherwise, if your real name information does not match your card number, there is definitely no way to bind successfully. If the binding is not successful, there is no way to get the money. So we should be careful with money. Especially when you enter these card numbers, you still need to use four as a group and then check them. This will ensure that your card number is correct.
Some people write the account opening branch wrong, or some people simply don't know which account opening branch it is. So at this time, you need to find out which branch your bank card is opened in. You can go to the nearest bank outlet and ask for information. This branch must be written down, because this information can be used in many places. If you don't fill in it yourself, you can, but some apps must be filled in, so there is no way. Therefore, when we fill in this information, we must compare all kinds of information well to ensure that what we fill in is correct.
When binding a bank card, you should also confirm the status of your bank card. If our bank card is frozen, there is no way to bind it, because at this time, bank cards are not allowed to conduct any transactions. At this time, you need to go to the bank to find out why your bank card is frozen. Because some people may have been sued for freezing bank cards, and some people may have frozen bank cards because of some improper operations, so they need to go to the bank to inquire.
