Chuzeat has been designed with solid security and privacy bases, our team of experts highlighted in the development phases a big criticism in the development phases in the development phases of simple printed QR Code. The scanning of the QR Code, in fact, identifies the room and the table to which the customer is sitting, but someone could painfully photograph the QR code and use it outside the premises by ordering vacuum dishes, resulting in economic damage to the restaurateur.
