About Tomoya Ogawa's work "Ie Pay

Tomoya Ogawa created "ie-Pay," an application that enables cashless money exchange for children receiving pocket money and small businesses. When a child receiving pocket money or a store reads the user's 2D code, a transaction request is sent to the web server (Apache & PHP) and the data is updated, which also updates the balance and history in the user's app. In addition to its simple and intuitive design, the web application can be used on older smartphones, making it suitable for a wide range of users.

Comment from Tomoya Ogawa

My joy at winning the Grand Prize

Last year, I was very close to missing out on the Kinki region representative, so I am very happy to have been able to make up for it.

Background and reason for creating this work

I had promised to help out during the summer vacation and receive an allowance, but I often didn't get it right away. I thought this was due to the progress of cashless payment, so I wanted to create a system that allows cashless payment even in the house.

What were the challenges in creating this system?

I changed the barcode of the member ID to a two-dimensional code, but the mechanism for reading the two-dimensional code was more complicated than I thought, and I had a lot of trouble.

Future Goals

We would like to develop additional features to make it easier to use, such as linking with external applications and displaying a graph of monthly usage.

■Comments from Mr. Abe, the instructor in charge of the project

Congratulations on winning the Grand Prize!

I thought that last year's work was also technically excellent and fully deserving of the award, but it was just one step away from being selected.

I am very happy to have won the award this year, building on last year's disappointment.

What is great about this work?

Tomoya's work is always born from the idea that "something like this would be useful" in everyday life. It is wonderful that his work incorporates the latest technology, which is as good as that of an adult engineer.

Tomoya Ogawa's episode

Tomoya stands out for his ability to identify and assemble what is needed to complete his work. If necessary, he can easily research on English-language technical sites with a translation engine in hand.

I am convinced that these children will be the ones who will go beyond Japan and spread their wings to the world.

Overview of Tech Kids Grand Prix 2023

The Tech Kids Grand Prix is a programming contest for elementary school students throughout Japan who will lead the 21st century. Under the slogan "You are the creators of the 21st century," the contest is judged from three perspectives: vision (dreams and worldviews you hold), product (creative ideas and works that embody your dreams), and presentation (attitude toward communicating your vision and products to society). Since its inaugural event in 2018, it has become the largest programming contest for elementary school students in Japan, with a total of more than 12,000 elementary school students participating.

The Tech Kids Grand Prix is open to all elementary school students and calls for original computer programming works. 47 prefectures in Japan are divided into 6 areas (Hokkaido-Tohoku, Kanto, Chubu, Kinki, Chugoku-Shikoku, Kyushu-Okinawa), each of which will host an "Area Qualifier". At each Area Qualifying Round, the area representatives will be selected through a multi-stage judging process. The top 10 representatives selected from each area will make a presentation at the finals in Shibuya, Tokyo, to determine the No. 1 elementary school programmer in Japan.
