The applicant shall submit the relevant credit certificate at the same time as submitting the complete application. The application form is attached with a credit card use contract, authorizing the issuing bank or relevant departments to investigate its relevant information and submit a statement of the authenticity of the information, which is signed by the applicant.
How to confirm whether the credit card is valid:
Confirm the validity of the credit card and contact the bank according to the contract signed with the issuing bank. Authorization is to further confirm the identity of the cardholder and the amount that can be used. Authorization is generally carried out when the usage specified in the contract is exceeded.
After receiving the authorization notice, the issuing bank will issue an authorization instruction according to the balance of the cardholder's deposit account and the agreement that the bank allows overdraft, and reply whether to agree to the transaction.
