the scenario:

I have shops and I want to create a point of sale for each shop which means each shop will have its own path to its POS, as we know there are shifted cashier for each branch so any cashier user can be logged in anywhere for each POS but only for shop POS.

my questions:

1- how to create multi-branch POS with different path for each one?
2- Is possible for the cashier user to be logged in by his username for each branch pos? if YES, then which branch POS will be logged in?
3- how to directly being log in to the POS without create the session?

Thanks,
