Is there a numbering system to be displayed in a big screen

[OJD03]

Is there a feature or app available on Square App Marketplace that can display customers' order numbers on a big screen and notify them when their food is ready for pickup in a food court? It's worth noting that all stores in the food court will be using a unified numbering system.

Hello OJD03,

I believe what you have in mind is not something that Square offers however, there are 3rd party services/apps that may work.  For example, check out this app and try their online demo.
