When you get the card (you'll need to call and request that they send you your rewards card) it will look like a credit card. You can use it practically anywhere when at WDW. Specifically, you'll be able to use it where credit cards are accepted so they will be able to swipe your card. Obviously it's not an actual credit card so you'll only be able to spend whatever amount of points you've earned.
We just ordered ours and we should be getting it very soon. Happy Shopping!!
