Cardholders can bring their ID cards and credit cards to Bank of Communications outlets to apply for the normal use of credit cards. According to the applicant's ID card and credit card number, the general staff will inquire about the specific reasons for the card being stopped in the banking system, and then tell the applicant how to solve the problem, and can resume using it after solving it as required.

The conditions required to apply for a credit card are as follows:

1. Generally speaking, the credit card application conditions of each bank are simple and the main age range (usually over 18 years old, the upper age limit of different banks can be used, some special cards can also be used for special age ranges, and some banks also have special age ranges for online application channels), and they have full civil capacity, legal and stable income and good credit status.

second, when applying for a credit card, you need to submit various documents to the bank to prove your comprehensive situation. Generally, there are ID cards, work permits, income certificates, financial certificates and residence certificates. The banking system scores according to the application materials provided by the applicant, and the comprehensive score meets the issuance conditions of the bank card, and the bank approves the card.

generally speaking, a stable job is a necessary condition for successfully applying for a credit card. Of course, this is not absolute. For example, many universities are now holding credit card business for college students. This is the unconditional issuance of credit cards, and college students can go to the bank with their personal certificates and student ID cards. Field, foreign personnel and active-duty general schools must issue cards in the name of individuals, issue temporary accounts issued by local public security departments or certificates issued by relevant departments, and have guarantee units with guarantee conditions or guarantors with local accounts working in the local area.

When logging in to online banking or mobile banking, the wrong inquiry password is entered, which causes the bank card to be locked for more than a specified number of times. Usually, after 24 hours, the bank card will be automatically unlocked; If the bank card is locked because the wrong transaction password is entered continuously during the cash deposit and withdrawal operation, and the bank card cannot be unlocked automatically, it needs to be unlocked at the bank outlet.

because of machine failure, judicial reasons, long-term non-use, etc., the bank card is locked, but it can't be unlocked automatically. The cardholder is required to bring the relevant documents to the bank outlet for cancellation.
