Before when you ordered and paid, you would get a pager that would go off to let you know your food was ready. Then you would go back up to the counter to retrieve your food.
Now, a new system is being tested. When you order your food, the Cast Member has a plastic number with a strip on it that gets scanned by a pod-like device on the counter. You receive the number, go pay, and then select a table in the dining room. Each table has an identical pod-like device where you scan your number when you sit down; a green light flashes to let you know your number has been accepted (it will beep if there is a problem, and you will have to scan the number again). Now that the system knows where you are sitting, when your food is ready a Cast Member will bring it to you, so you don’t have to get up again.
