How are library fines worked out?
A library fine is your daily rate multiplied by the days a book is late. At ₹2 a day, a book returned nine days late carries an ₹18 fine.
Each fine is recorded against the student with the amount paid and the balance, so a part payment today and the rest next week both show. If that student comes to borrow again while a fine is pending, the desk sees a warning first. Library fines are kept in the library module, separate from the fee bill.
