I'm a college student, do I have money on my social security card?

People who participate in the work, the unit from the salary income on behalf of the social security contributions to the social security card account, so such people have money in the social security card account, but can not withdraw cash, and now the social security, medical insurance in a card, collectively known as social security card, for medical expenses, retirement pay. College students' social security card may only have the function of medical insurance, right, because you have not participated in the work, no income for the deposit, even the source of medical expenses should also be the deposit of tuition fees when there is a block of student insurance premiums and other funds.
