在網際網路上作電子化應用時，以往因為無法辨識使用者是誰而無法提供某些服務。有了外來人口自然人憑證IC卡後，機關單位就可以驗證網際網路的使用者身分，更進一步在網路上提供個人化的服務，例如網路報稅、勞保及健保網路查詢…等業務。
When electronic applications are used on the Internet, some of the services could not be provided in the past because it was impossible to identify a user. With the alien citizen natural person certificate IC card, related authorities can verify the identity of the user on the Interne, and can further provide personalized services such as online tax filing, labor insurance and health insurance online inquiry, and other services.

目前提供的網路申辦服務為個人綜所稅結算申報、勞工保險局e化服務系統、全民健康保險個人健保資料網路服務作業、線上申辦入出國日期證明書等等…。其他應用將陸續開發上線，未來將提供更多的應用服務。有關各應用系統之詳細服務內容，請參閱各網站說明。
At present, the service provided on the Internet include Individual Income Tax Filing, Bureau of Labor Insurance’s e-Service System, National Health Insurance’s Individual Health Information Network Service Operation, Online Application for Certificate of the Date of Entry and Exit, etc. Other applications will be developed and provided, and more application services will be provided in the future. For detailed service content of each application system, please refer to the description provided on different websites for the services of different application systems in detail.
