Using My Number Card for the "Prevention of Drinking by People Under 20" School Festival

People of various ages visit university school festivals. At school festivals where alcohol is served, reliable age verification is required to prevent serving alcohol to people under 20 years old.

Digital Agency, together with school festival executive committees from various regions, is promoting age-verification initiatives using My Number Card. While ensuring age-verification, we aim to minimize the burden on visitors and student staff as much as possible. The use of My Number Card is expanding to such various situations.

Age verification by My Number Card

You can use My Number Card and My Number Card on Smartphone (both iPhones / Android) to verify your age.

About the app for reading the IC chip in My Number Card

The university's school festival is a place where visitors under the age of 20 and those over the age of 20 coexist. Until now, the student staff responsible for managing the festival have been burdened with verifying ages by visually checking identity verification documents.

By using the "Digital Agency the app for reading the IC chip in My Number Card ( Web Service Application) " provided by Digital Agency, the School Festival Executive Committee can both confirm age reliably and reduce the administrative burden.

Flow of age confirmation

• 1. A visitor shows "My Number Card" and "My Number Card on Smartphone" to a student staff.
• 2. The student staff reads in "the app for reading the IC chip in My Number Card" and confirms that he is over 20 years old.
• 3. After the confirmation, you can purchase alcohol according to the rules of each school festival, such as issuing a wristband.

• *Some universities limit the subject of confirmation to "My Number Card on Smartphone".

My Number Card

The IC chip of the My Number Card is scanned to verify personal information. Compared to visual confirmation of only the ticket surface, this leads to measures against impersonation using forged identity verification documents. Confirmation can be made using only the information written on the ticket surface, and entering a PIN is not required.

My Number Card on Smartphone

The only information checked at the app for reading the IC chip in My Number Card is "whether you are over 20 years old or under 20 years old." You can receive age verification without giving personal information that is not necessary for age verification, such as your name and address, or even your actual age to the student staff.

School festival to be held

• *The content and time vary depending on the school festival.
• * My Number Card on Android will be scanned for the school festival held after Tuesday, October 20, 2026.

You can use My Number Card on Smartphone.

"My Number Card on Smartphone" is a service that allows you to add a function in My Number Card to your smartphone and use it. Instead of entering a PIN number, biometric authentication such as face and fingerprint is used to easily and safely verify identity.

If you have a My Number Card on Smartphone ready to use before going out, you can confirm your age just with your smartphone without taking the My Number Card out of your wallet at the school festival of the applicable university.
