Conclusion: Social security card itself cannot be directly used as collateral for loans, nor can it be used as a basis to prove repayment ability. Lending institutions usually require loan applicants to provide more comprehensive financial certificates, such as work certificates, income certificates, identity cards and bank accounts, to assess their repayment ability. Some banks, such as China Merchants Bank, provide "social security consumer loans" to customers who have paid social security for more than one year. This kind of loan can be used for all kinds of daily consumption, with a high amount and can be recycled. But even so, the main function of social security card in loan application is as identification, which helps to prove the social security status of individuals.

Specifically, although the social security card has a wide range of functions, such as real-time settlement of medical insurance, handling of old-age insurance, and registration of job hunting and unemployment. , cannot be directly used for loan approval. If a loan is needed, the individual must provide complete credit certification materials to ensure that the lending institution has a comprehensive understanding and confidence in the borrower's financial situation. Applicants who want to borrow money through social security cards should be clear about their needs and prepare complete loan documents to improve the possibility of successful application.
