Interaction method and system based on quick cash register of cash register system

Abstract

This invention provides an interactive method and system for quick checkout based on a POS system, comprising: defining a page functional component structure, binding the component attributes corresponding to the page functional component structure and initializing an operation queue, and generating a unified operation view; obtaining the shortcut key identifier and corresponding weight of each functional component, and updating the operation queue corresponding to each page functional component in the unified operation view; listening for keyboard events, polling the updated operation queue, and executing the corresponding response event bound to each page functional component. This invention achieves quick checkout by registering the functional components of the checkout page, binding the mapping relationship between function codes and shortcut keys, and generating an operation queue.

Claims
