Can an old and a small postal savings account save money?

One old and one small bank card can save money, and "one old and one small" medical insurance.

Since 2007, Beijing has officially started urban residents to participate in the pilot work of basic medical insurance, and gradually brought "one old and one small", that is, the urban insecure elderly, school students and preschool children, into the basic medical insurance system, involving about 250,000 people and 2 million people respectively.

The new social security card has two accounts, one is a social security card account and the other is a deposit account. The deposit account of social security card can be used for deposit and withdrawal business. According to the relevant regulations, the current social security card is a bank card with medical insurance function, so the social security card has the same function as the bank, and the business that the bank card can handle can also be handled through the social security card. However, because the social security card is divided into two different accounts, we use its bank account when using the social security card, so the money deposited will directly appear in the bank account. When we see a doctor in a hospital, we use the authority in the social security account, so we can't directly consume the amount in the deposit account when we see a doctor in a hospital.
