We will develop a menu-ordering-payment processing app, specialized for bars and night clubs.

The app will have a client interface:
The client will read the qr code nearest to them -each location in the bar will have its own qr code, which redirects to the menu and adds the table ID to the link 
view menu (generated by products entered in the admin interface)w
place orders
select delivery method (pick up from the bar/bring the product to where the user is 
pay for the orders (we will use mastercard click to pay api registered to the bar (save credit card, etc.))
the user is notified when their order is ready/their order is delivered to their table

The app will also have an admin interface.
Admin will be able to add/edit/list/delete "tables" (locations in the bar where a unique qr code is placed) and generate qr codes for these tables.
Admin will be able to add/edit/list/delete product categories, properties associated with these categories (for example: Category: Sweet Cocktails, Properties: ingredients, warnings, allergens).
Admin will be able to add/edit/list/delete products to categories. Every product will have a name, a price, a photo (optional) and the relevant data for category properties (for example ingredients, warnings and allergens for the product. these will come from the category's properties).

The app will also have a staff interface.
All client orders will be listed on the staff interface. The design must be as clear and interaction-free as possible. 
Client orders and their contents will be listed on the interface. When the order is ready, the staff user will click "order ready"
Depending on the selected delivery method, either a notification will be sent to the client to come and pick up their order, or a notification will be sent to the relevant bar staff to pick up the order from the bar and deliver it to the client at table Id.
Finished orders will be removed from the interface.

All orders have to be logged and recorded for future tax purposes.
