How do Gift cards + gift card machines, work?

Gift cards are just like cash except that you swipe it through like a credit card to make the payment. Drawbacks are that someone else can use the card; some firms charge a monthly fee after a while to "eat up" the balance. You may not be able to use it at some places or it could be for a specific store.
