What if the number of postal bank cards exceeds the limit?

The first two methods are easy to deal with repeatedly. If you have enough time, I suggest you handle it directly at the counter:

If it is because the number of online transactions exceeds the limit, then online transactions cannot be made on the same day. Especially if the bank card is a second-class account, there is generally a daily trading limit of 1 000. In this case, the trading limit can usually be restored the next day. However, if you exceed the trading quota, you can't do online trading any more. You have to go to the bank counter to handle the relevant quota.
