The problem KhaanaKhaata solves

Efficient Money Handling
All the transactions the student would make in his/her school would be completely cashless. The solution shall function as a credit-based system

The students would be provided the calorific value of every food item. The parents would hence be able to monitor the dietary habits of their children.
Transparency and Accountability
The parents would be able to observe exactly where and how much money their child is spending.
