When you want to redeem your points, you need to get a separate card - it looks like a hybrid between a gift card and a credit card. When you receive the card, you go online and transfer your points (dollars) onto the card and then you use it the same as you would any credit card throughout the parks. Note, though, that it only works at Disney owned venues - occasionally we will try to use it with a vendor of sorts and are told that it will not work. Be sure to keep the card at the end of your trip even if you've used all of your points; when you accumulate more points, you will use the same card for purposes of transferring the points onto the card for use.
