How can a social security card be used by a 7-year-old boy?

Children's social security cards can be activated in issuing banks, local social security service centers and social security cooperation institutions. You can also activate it directly when using the social security card, such as reimbursement of medical expenses or purchase of medicines. It should be noted that children under the age of 7 do not need to apply for social security cards. They only need to enjoy relevant treatment in designated medical institutions with their household registration books. Children over 7 years old need to be accompanied by guardians because they don't have ID cards, and they need to bring their household registration books to the local social security service center to apply for social security cards.
