An insufficient credit card comprehensive score means that you do not fully meet the conditions for applying for a credit card.

The credit card comprehensive score is the bank's evaluation of the card applicant's comprehensive credit based on the information provided by the credit card applicant and using a fixed scoring system.

There are many factors that affect the comprehensive score, including marital status, technical title, job, financial ability, personal housing, credit record, academic qualifications, etc. The "comprehensive score" is obtained when all scores are accumulated.
