When a card issuer notifies the judicial police authority in accordance with the regulations in the preceding paragraph, it shall use the telephone, fax, email, electronic platform, or other feasible means. It shall also provide documents of abnormal credit cards suspected of involvement in fraud, the identity of the cardholder, relevant transaction records, or other documents required to be provided under the notification method based on the request.
Article   23    After receiving a report from the card issuer, the judicial police authority shall notify the card issuer by official letter within 20 days whether to continue or lift the control measures imposed on the abnormal credit card suspected of involvement in fraud. If the judicial police authority fails to notify the card issuer within this period, the card issuer may continue to apply the control measures.
In case of major contingencies, the judicial police authority may send the notification in the preceding paragraph to the card issuer by telephone, fax, email, or other feasible means, followed by a confirming official letter and documents which should be delivered within five business days.
