The chip on the National Card will have 16 kilobytes of memory, so in the future not only could functions such as transaction confirmation, electronic signing of documents and the storing of electronic "cash" be added, it could also even allow for the establishment of a huge national database which could be used for surveys of the public or to provide information on spending habits and the movement of goods.
由於國民卡上的晶片擁有 16KB 的記憶空間，未來除了有可能擴展到做為交易認證機制、電子簽名、電子錢包，甚至建立起龐大的國民基本資料庫，可供給民意調查或是銷售情報與商品流動資訊之用。
