It is a neat concept that could catch on.
There is a high-tech program in place at a Florida middle school; here is how it works.
A computer system that parents can use to put money on their child's lunch account can also be used to keep them healthy.
Before a student pays for their meal, the computer can alert food services workers that a child is diabetic, or has a severe allergy.
It is also a way for parents to help their children watch their weight.
Principal Debra Johnson said, "The software allows for a field that you can put a special message in, so what we're using it for is for our students that have specific dietary requirements."
Johnson added, "A parent could say no a la carte and that could prevent the child from buying cookies and chips and you know the food that parents might perceive as not as healthy as the other.”
The amount of money a child spends for lunch can be limited as well if it is written in their account.
