A new idea in teaching kids to save

I recently learned about a new way to teach kids about the value of money and how to save.
It's called Kidsave and very representative of how your children see you dealing with money on a daily basis.

Riv from Sacred Spaces Home said "Just like checking an online banking account, it automatically deposits "virtual" allowance to each account, has interest that's accrued (for saving) and every time they want to withdraw, they give us a withdrawal slip and we give them the cash and withdraw "virtually". It not only teaches them how the "real" world works but also relieves us of the hassle to always have exact change or cash around."
