Bank card freezing refers to the measures taken by banks to prevent fraud and protect the safety of customer accounts. Usually, if the bank finds that the card has been used abnormally or is suspected of fraud, it will freeze the card immediately. In this case, the cardholder needs to provide relevant certification materials, and the card can be unfrozen only after the bank has reviewed it. Usually the audit period is 15 days.

During this 15 day, the bank will verify the use of the card and the identity information of the cardholder. If the confirmation card is illegally used or suspected of fraud, the bank has the right to freeze or cancel the card for a long time. If the card is used normally, the bank will cancel it after the audit period.
