Thanks to our new generation QR code scanning application, you can help track the service by scanning the QR code on the back of the seats when you get on the service. By scanning the QR codes, the seat number can be tracked, and the occupancy rate in the service you have used can be determined. This application, which is published in addition to the "Rotaban" application, provides you with various conveniences and eliminates the obligation to carry a card with you.
