A simple ordering app using iPad or iPhone. Customers tap a choice of 10 items via an iPad on their table. Kitchen/Cashier receives the order instantly. I need a LAMP Stack as backend via Internal WIFI, Internet not required. This is an experimental project but need full documentation. You should have done something similar using LAMP Stack. Everything can be open source. No UI, No UX, just a functional app with a backend that can be installed on any computers.
