Online application acceptance for the "special fixed amount benefit", in which the government provides a uniform payment of 100,000 yen per person, began on May 1. Since the reception started on May 7th in the municipality where I live, I immediately tried to apply online, but unfortunately I could not complete the procedure until the end. There was a pitfall of "revocation of digital certificate for signature".
Failed to apply for "special fixed amount benefit" onlineFor online application, I prepared my number card and a smartphone (iPhone 11 Pro) compatible with Mynaportal. I also downloaded the smartphone application "Mynaportal AP", which is required when reading my number card, in advance.
Also, I knew that if I made a mistake in the password for my number card's "digital certificate for signature" five times in a row during the procedure, it would be locked and I had to go to the government office to unlock it, so I had a copy of the password at hand. Was also prepared. Now you're ready to go.
After confirming that online application acceptance has started, access the application page for special flat-rate benefits from "Mynaportal". I entered the required information such as contact information such as telephone number, address, name, date of birth, bank account information, applicant information, and attached a photo of the cash card of the transfer destination.
Access the minor portal and fill in the required items.Input can be omitted by reading my number cardAll you have to do is add an electronic signature using your My Number card and send it. Enter the password of the digital certificate for signature in the linked Mynaportal AP and read the My Number card on the iPhone. Then, "Successfully attached the digital signature" was displayed. When I checked the site with this, there was a ruthless red error saying "The digital certificate for signature has expired. Please go through the procedure for issuing the digital certificate at the municipal office." It was displayed ...
One step further, the message "The digital certificate for signature has expired" is displayed and abandoned.Apparently, if you don't reissue the electronic certificate at the counter of the government office, you can't proceed further. I'm trying to apply online in a non-face-to-face manner to prevent infection with the new coronavirus, but if I go to the government office for the issuance procedure, I'm overwhelmed. At this point, my heart broke and I gave up my crying online application and decided to switch to mail.
Why has the digital certificate for signing my number card expired? The reason is that when I moved about a year and a half ago and went through the procedure to change the address of my number card at the government office, I did not reissue the digital certificate for signature.
To explain in a little more detail, the IC chip of My Number Card is used for "electronic signature certificate" used when creating and sending electronic documents on the Internet, and for logging in to Mynaportal and issuing certificates at convenience stores. It is equipped with two electronic certificates called "electronic certificate for user certification".
Explanatory drawing of digital certificate (from the website of the Ministry of Internal Affairs and Communications)After issuing the My Number card, the signature electronic certificate required for this online application will change its address and name depending on the notification of resident transfer due to moving (moving in, moving, etc.) and the notification of family register (marriage, etc.). And, because the contents of the electronic certificate and the resident's card are different, it will expire. Therefore, it is necessary for the government office to issue a new electronic certificate for signature.
Many people may have said that they had to change the address of their Individual Number Card at the government office when they moved. It is true that the address contents written on the surface of the Individual Number Card will be overwritten by this, but in fact, the digital certificate for signature is not renewed by that alone, and a separate procedure is required. In other words, changing your address is not enough.
