There is no minimum amount of money in your account. So I have to charge you penalty fine.
The system checks on the sufficiency of the credit balance by considering the minimum price and if the balance is sufficient, the system will display a Onboarded successfully message to the passenger while it sends a notification as passenger onboarded to the driver.
The inspector normally checks about this.One day, the bus John was traveling on was checked by an inspector.
That day John's account did not have enough money to go to the end of the trip. This was observed by the inspector. He charged John a penalty fine.
Then he determined not to travel in public transport without a valid token and if he doesn't have the minimum price for the journey.
At the next stop, John credited his account and paid the extra penalty fee too.
Finally John arrived at his college on time. In this system, everything is done through a digital method, which can save time for the passenger as well as the bus drivers.
