The credit card transaction password can't be set. Call customer service to ask what the revised information is, and it hasn't been submitted yet. Then it usually takes several working days to complete. If it is a new card, please open the card by phone first, and it can only be used after the bank system opens the card successfully. You can use it after opening the card by phone or online. If it is a used card, you should be able to change the password immediately by calling the bank directly. The customer service said that the revised information has not been submitted because there is something wrong with their banking system and it needs to be updated for a period of time, usually 3 to 7 working days. You should follow up and change the password at that time.
