A first debit card can feel like a major step toward independence for a child, but tapping a card is much easier than understanding what happens to the money behind it. Before handing over that plastic, parents can use the moment to teach money skills for kids that will matter long after allowances and lunch purchases disappear. A debit card generally draws money directly from an account, meaning every purchase reduces the amount available for something else. Teaching a few practical habits beforehand can turn that first card into a valuable financial lesson rather than simply another way to spend.
