I have an idea for public transport. There were much written about it.
I'd like to offer a special system of payment. So, all you'll need to do when getting into a bus/microbus is to bring your special plastic card to the screen surface of the electronic device located on one of the sides of the bus. This card would contain information on the cost of your trip and on the resources left. It also can be distributed by educational organizations to the students or by working organizations to the personnel. The system of discounts can be foreseen depending on the frequency of a passenger's trips and counted and fixed on this car chip or something like that.
I'd like it start to work soon, and you?
