1. If there are risks in the customer account or the banking system is upgraded, the bank will suspend the customer channel transaction. Specifically, when the channel transaction is suspended, it may be that the machinery and equipment of CCB have failed or the banking system has been upgraded, and the banking machinery needs regular maintenance and cannot be used normally during the maintenance process. In this case, CCB will issue an announcement to remind customers that they can conduct channel transactions again after machine maintenance or upgrade.

2. Secondly, the customer channel may be suspended due to the abnormal operation of the card, and the bank cannot confirm whether the operation is aimed at itself, so it takes special and necessary measures to protect the rights and interests of customers, protect the security of customer accounts and prevent risks.

: How to solve the suspension problem?

1. Call the official customer service phone of the bank first to find out whether your bank card has been suspended because it has not been used for half a year. As the name implies, off-site business refers to the suspension of all services except on-site business, such as services initiated by personal customers' mobile banking, online banking, WeChat, Alipay, pos machines and ATM self-service machines. This is a security measure taken by the banking system to prevent the loss of the bank card, and the cardholder did not urgently handle the proposed security service. If this is the case, the bank card holder only needs to bring his ID card to any branch of the bank and handle it according to the requirements of the counter staff, then the restriction can be lifted and the normal use of the account can be resumed. If it is not because the bank card has not been used for six months, it is likely that some customer identity documents left in the bank have expired, expired or incomplete registration when risks arise or the banking system is upgraded, and the bank will suspend customer channel transactions. Then the cardholder needs to go to the bank to improve the updated information in order to restore the normal use of the bank card.

2. If it is caused by not using the bank card for a long time, you can consult the customer service of the bank card and handle it at any outlet. If the cardholder really seldom uses the bank card or does not use the bank card at all, but wants to avoid the suspension of the customer channel trading service due to the long-term non-use of the bank card, then the cardholder can use online banking, Alipay, WeChat and other payment means to make one or more payments within six months after opening the account. It should be noted that the funds deducted from the management fee of the bank card itself are not regarded as transaction records.
