 In the past, tax reporting or querying labor and health insurance information often had to struggle with card readers, component installation, and system compatibility. The cumbersome login process greatly reduced the convenience of digital services. In view of this, the Ministry of the Interior launched the "TW FidO" mobile natural person credential app in 2022, declaring the arrival of the "cardless era". However, at that time, the application was mostly limited to government fees until the third reading of the amendment to the Electronic Signature Law on April 30, 2024, which gave digital signatures the same legal status as physical signatures. Nowadays, the application scope of mobile natural person certificates has expanded beyond the public sector, extending to financial account opening, commercial contract signing, and various digital services in the private sector. This issue introduces the use and application methods of 'Legal Column'. Please feel free to make more use of it.Voucher Purpose
The common uses of the 'Action Natural Person Certificate' are as follows:
Online tax reporting: settlement and declaration of personal comprehensive income tax.

Application Method
The application method for the certificate of action for natural persons is as follows:
1. For those with natural person credentials: Download the app, prepare the natural person credential IC card, enter the unified ID number and PIN code, and complete the mobile phone card sensing.
2. For those without a natural person certificate: Download the app and bring your ID card to the counter of the household registration office to apply.
Note: The online application for mobile natural person credentials is limited to those with existing physical cards.
Anti fraud propaganda
Whether it is physical IC cards, natural person certificates, or mobile app natural person certificates, they all have functions such as identity recognition, digital signatures, and data encryption and decryption, providing convenient digital services. According to Taiwan's Electronic Signature Law, the digital signature of a natural person certificate is a type of electronic signature that has the legal effect of "presumed" to be personally signed or stamped by the individual. If one hands over their natural person credentials to others for use, it may result in legal liability and personal property damage if personal information is leaked or used fraudulently in the future.
Therefore, if it is found that someone with ulterior motives is persuading to open a natural person certificate and requesting the delivery of a card, password, or mobile phone for online inquiry, it is recommended to first call the 24-hour "165" anti fraud consultation hotline for verification. Do not easily disclose personal information to avoid fraud.
The 'Mobile Natural Person Certificate' is not only a technological upgrade of digital services, but also a comprehensive reform from administrative processes to legal protection. We believe that in the future, it will be an essential 'digital passport' for every citizen to travel in the digital world. (Source: Ministry of the Interior Action Natural Person Certificate)
