On every table in your restaurant place a small Bar Buddie sticker (or a stand) with brief instructions, and a QR code
Guests scan the QR code and after registration, starts ordering thru their favorite chat app such as WhatsApp, Messenger, SMS, etc – without having to install anything or logging in
The waiter assigned to the table receives on his device (shared tablet / smartphone) a notification about a new order, after the products are selected, and order is filed
Guests can use Bar Buddy anytime they wish to make additional orders, consult the menu, ask for for their bill, etc. The payment link sent back opens Payconiq or other banking app for contactless payment.
