As the name suggests, a self-ordering kiosk - or self-service kiosk, as the names are used interchangeably - is a piece of restaurant technology that allows customers to browse the menu, place their order, and pay. The system should be operated with an easy-to-use touchscreen that guides customers through the ordering process. This interface is completely customizable, so restaurants can integrate menu modifiers, add-on options, and suggestions. Self-ordering restaurant kiosks usually supplement a traditional counter ordering system, but some businesses have even used them to completely replace face-to-face ordering.
