QR Scanner Pro: QR code scanner with callback function support

What this solution does

The QR Scanner Pro module enables scanning of QR codes and barcodes directly in the browser without installing additional applications. It can be used to manage inventory and product search, register event attendees, verify tickets, process requests, and perform other tasks. The scan result can be redirected to a specific page or processed via a custom PHP function. Ready-to-use code examples accelerate implementation, while flexible settings allow the interface to adapt to any design and usage scenario.

The module supports a wide range of codes used in trade, logistics, and document management. It recognizes QR codes containing links, contact data, text, and JSON. It works with Data Matrix codes, including product marking in the Honest Sign system. It supports reading Aztec codes for electronic tickets and boarding passes. The PDF417 format is supported for documents, IDs, and transport tickets. Standard product barcodes EAN-13, EAN-8, UPC-A, and UPC-E are also recognized.

The module supports recognition of Code 128, Code 39, Code 93, and ITF barcodes used for warehouse and logistics labeling, as well as on invoices and transport packaging. It also processes Codabar codes, which are used in specific library, medical, and accounting systems.

Recognition occurs directly on the user's device. The module utilizes built-in browser capabilities; if these are unavailable, a JavaScript recognition mechanism is activated. This allows codes to be read in modern browsers without installing a separate application.

Real-time scanning is performed when a user opens a website page and points the camera at the code. The scanner uses the device's main (rear) camera, and recognition happens automatically without button presses.

If the camera is unavailable, scanning from a file is supported. Users can upload a photo or screenshot containing a QR code or barcode, and the data is extracted from the image.

The module offers two result processing modes. A callback function sends the code content to a PHP function, and the function's response is displayed to the user in a popup window without reloading the page. The redirect mode sends the user to a specified page.

The module provides a ready-to-use handler for rapid deployment. The package includes a demonstration example that displays JSON data as a list, makes links clickable, and renders plain text without additional formatting.

Upon installation, a dedicated /qr/ section is automatically created with ready-made demo pages. These pages showcase examples of both processing modes, allowing users to quickly familiarize themselves with the module's capabilities and verify its functionality.

The digimatix:qr.scanner component can be placed on any page or within any site template. Separate scenarios and parameters can be configured for different pages.

The appearance is customizable via the component template. Users can copy and modify the template to match the site's design, adjusting styling, tooltips, and other interface elements.

The scanner features an adaptive interface optimized for use on smartphones and tablets.

The module is versatile and supports the implementation of any post-scan scenarios, including authentication, ticket verification, inventory management, goods receipt, and promotional campaigns.

The quick start scenario ensures that a working example and the /qr/ section are available immediately after installation.

Integration is straightforward: simply place the component on a page, and it begins functioning.

The module offers design flexibility, allowing you to create custom templates, styles, tooltips, and hover frames. Scenario scalability is supported by enabling distinct component parameters for different URLs based on specific tasks. It requires minimal configuration for marketing and content teams while remaining extensible for developers.

The module is suitable for online stores and retail outlets to search for products by barcode, verify marking, and open product cards via QR codes. Event organizers use it to validate electronic tickets and register visitors. Warehouses and logistics companies utilize it for receiving and tracking goods, reconciling inventory, and managing product logistics. Service companies apply QR stickers to equipment to enable quick access to related tickets, object cards, or contact forms. Organizations tracking attendance register employees, students, and event participants using individual QR codes. Restaurants, cafes, and hotels employ the solution to create digital menus, navigate to booking pages and loyalty programs, and implement custom QR code workflows.

Install the module. Upon completion, the /qr/ section is automatically created containing the digimatix:qr.scanner component. This section serves as a ready-made page for testing scanner functionality.

Select one of three methods for processing QR code or barcode data: callback function, URL mode, or a custom handler.

For the callback method, specify a function name in the component parameters, for example Digimatix\QrScanner\Functions::ExampleQr($_REQUEST["data"]). Implement a custom handler that accepts data from $_REQUEST["data"] and performs required actions such as database recording, displaying a modal window, or redirecting the user.

In URL mode, define the address to which the parameter containing the scanned code data will be sent. The request direction (GET or POST) is configured separately.

Configure the interface appearance. If necessary, copy the component template to the site template and modify styles, tooltips, and the hover frame design to ensure the scanner matches the project design.

Configure scenarios for different tasks. Place the component on the required pages and assign individual parameters for each page.

Example of a minimal handler (callback):

PHP opening tag

namespace Digimatix\QrScanner;

class Functions {

public static function ExampleQr($data): void {

// Validation and logging

The QR Scanner Pro module by DIGIMATIX provides QR code scanning with support for callback functions. The provided code fragment demonstrates basic data handling: it validates that the incoming $data parameter is a non-empty string. If the parameter is missing or empty, the system returns an HTTP 400 error code. The business logic block includes capabilities for saving data, verifying it, and sending notifications, such as via the \Bitrix\Main\Mail\Event::send method. The final part of the code allows for an optional 'OK' response output when using a component template.
