Attached guests to the order
If you have a closed territory of your hotel, where a guest can move and order services or goods throughout the territory, then a system that binds the guest's order to his card, bracelet or code in the phone is suitable for you. That will allow you not to search for a guest's order when he moves around your territory, just an employee scans the code on any medium and the program understands who this guest is and where his order is in order to place a dish or service on him in just a couple of clicks
