E-medicare vouchers are health insurance vouchers that are generated electronically and can be used to settle medical bills at medical institutions. Holders can display their e-Medicare vouchers through electronic devices such as cell phones, eliminating the need to carry a physical card.
A social security card, on the other hand, refers to a physical card issued by the national social insurance system for participants to manage and use social insurance-related services. The social security card records information about the individual's participation in the program and his or her authority to use social insurance services, among other things.
While both relate to health insurance, electronic health insurance vouchers are mainly used for medical billing, while social security cards are physical cards issued to manage and use social insurance services.
