The application "3 plus" allows families with several children:
- information about the participants who approve the discounts
- 3+ online department stores
- free parking hours
- gifts or exchange of goods between families
- paying utility bills with a reduction
- online banking

Our application also allows proud card holders (for families with three or more children) free parking hours that they approve local governments through their companies that are in charge of charging for parking.

For the most part, we have solved this possibility of using approved free hours on a monthly basis through our application which has a platform for registered users and a platform for controllers and by scanning the user's personal QR codes by the controller.
