2. When the overdraft exceeds the limit, the bank will immediately freeze your credit card.

3. If you enter the password incorrectly three times in a row, the bank system will automatically lock the credit card password, which is similar to freezing, but not freezing. It will be automatically canceled after 24 hours.
