The vNetic workshops ("日比野工作室")  help the one who need IT consultation services with limited/ without budgets. If you have a good idea and without budgets, we may help you to build it. But you are willing to share it with the others. The "Portable Attendance Logger" is made for a small ruby football club for free. As they do not have budget and experience to develop the APP. And now the APP is released for public free to use. The APP can benefit for the others. It is a triple Win situation.
