Although the public will be required to change to this card in the future, the decision whether or not to include functions such as the electronic signing of documents and the carrying of electronic cash will be made by the individual cardholder. Lee says that the government is moving towards multiple cards with multiple functions, not to one all-purpose card.
未來，民眾雖然被強制換卡，不過電子簽章認證、電子錢包等功能是由民眾自行選擇使用與否，而政府未來也將朝識別、金融、交通不同目的「多卡多用途」方式運作，而非一卡走天下。
