Drawer Status Detection

Overview

The purpose of this project is to have the ability to detect the status of the cash drawer (Open/Close).

Scope

Functional Requirements

Definition

The drawer needs to be a type of drawer that sends its status: Whether it is opened or closed

There are five ways to open the drawer:

The top three will have their toolbar buttons disabled if the drawer is opened, if you click them an error will be raised. They will be enabled when the user closes the cash drawer.

The last two will raise a popup that prevent the user to continue if the drawer is still opened. The popup will disappear once the drawer gets closed.

Hardware url

Status Checker

Every time the cash drawer gets opened WebPOS begins the detection of its status and it will stop once the drawer gets closed. There are 2 cases:

  1. Detection on load, on click "Open Drawer" button and on payments
  2. Detection Cash up, Cash management and Initial count

On the first one a popup will rise to prevent the user to continue its labor and the second one will only disable several buttons.

Popup

The popup will show only if the drawer gets opened. There are different cases:

Load

When WebPOS gets loaded it will check the status of the drawer. If it is closed it will be transparent to the user but if it is opened the popup will rise. It will ask to close the drawer.

Open Drawer button

On click the popup will rise, it will ask to close the drawer.

Payments
