Connect the web application to the stationary QR scanner.
It is a web application for food accounting. Scanning QR codes is implemented using the phone's camera.
The application needs to be connected to a QR scanner that will be stationary. There should also be a display to view the result when scanning.
The QR scanner is not available yet. Help is needed to select the optimal one and connect it to the web application.

We can take this turnkey - select a stationary QR scanner, check the USB HID or COM mode, connect it to the web application, and create a results screen for the operator. In terms of timing, I would say 5-7 working days after access to the test environment, budget - 22,000 UAH.
Look, there’s a nuance here - it’s better to choose the scanner not by price, but by the operating mode with the browser and how the web application accepts the QR. The simplest way is for the scanner to work like a keyboard, the web page accepts the code, checks it on the server, and displays the result on a separate screen. If a stable stationary point is needed, a kiosk mode can be set up on a tablet, mini PC, or monitor.
For an accurate estimate, two things are needed =)
> What the web application is currently built on and whether there is access to the code or test environment
> What exactly the display should show after scanning - full name, power status, error, remaining limit, or another result.

Overall, it’s fine, the task is small, but it’s better not to guess the details of the implementation - one unsuccessful scanner can take more time than the integration itself.

We will select a reliable stationary QR scanner with keyboard emulation mode (USB-HID) support and develop a lightweight JS logic for instant output of results on the screen without rewriting the architecture of your web application.
What specific OS (Windows, Android, or Linux) do you plan to install on the stationary display at the food accounting point, so we can choose between a classic USB scanner "in keyboard wedge" mode or a standalone Ethernet/Wi-Fi scanner that sends HTTP requests directly to your backend?
Budget and timelines will be discussed in private correspondence.

We already have a practically ready similar solution for connecting scanners to web applications, which can be quickly adapted to your food accounting and launch the first working version. ))
The software timeline is estimated at 5-7 working days after access to the application and a brief on-site scenario agreement.
Regarding the budget, I would allocate from 18,000 UAH for selecting a scanner, checking the connection option, modifying the web application for stationary scanning, and the result screen.
Look, there’s a nuance here - the simplest and most reliable way, if the application allows, is to use a keyboard mode scanner, where the QR code is inserted into the active field, and the application processes the event.
If a separate display is needed without operator involvement, then it’s better to create a kiosk mode on a tablet or mini PC, so that after scanning, the status, name, limit, or error is automatically displayed.
…
We need to clarify two things:
- Does the web application open in a browser on a regular computer or tablet?
- What exactly should be displayed on the screen after scanning - only success or also the person's data, balance, reason for refusal?
Relevant examples of our systems:
- https://business.ingello.com/forma-crm - similar logic of accounting, roles, and workflows in the internal system
- https://business.ingello.com/platforma - an example of a more complex platform with business logic and automation
- https://systems-fl.ingello.com/ua - a brief about Ingello Systems and the approach to such tasks
We can keep it simple - first, we check the current QR mechanism, select 1-2 scanner models, do a test integration, and then refine the result screen to a normal working scenario. =)
I am available here on the marketplace; we can discuss the details right now.

Hello! I am ready to implement this project turnkey, connect a stationary QR scanner to your web application, set up the output of results on the display, and help with the selection of reliable equipment.
For integration, I suggest using a scanner with keyboard emulation or the WebHID API, which will allow data to be transmitted directly to the browser without installing complex additional software on the workstation.
I will help launch everything on your hosting and test the hardware, please message me for discussing the details.
