FAQ
After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.
Example:
Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.

Some PHP packages are not free to download and because of that hosted in private repositories.
In this case some credentials are needed to access such packages.
Please use the auth.json textarea to insert credentials, if a package is coming from a private repository.

- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package laravel-qrcode
jamal/laravel-qrcode
A dependency-free Laravel QR Code generator with a pure-PHP SVG renderer and optional PNG via GD/Imagick.
Standards Compliance
- Implements ISO/IEC 18004 for Versions 1–40 (auto-selected from the data length).
- Modes: Numeric, Alphanumeric, Byte (UTF-8).
- Error correction: L, M, Q, H via Reed–Solomon over GF(256).
- Masking: evaluates masks 0–7 and selects the lowest-penalty matrix.
- Full function patterns: finder, separators, timing, alignment (v2+), dark module, 15-bit format information (both copies), and 18-bit version information (v7+).
- Output is byte-identical to reference encoders and decodes on standard readers (verified with ZBar across modes, ECC levels, and versions 1–13+).
- Quiet zone default is 4 modules (configurable via
margin).
Installation
Quick Start
Examples
1) SVG and PNG
2) Save to file
3) Controller Response
4) Data URI
5) Blade directive
6) ECC Level, Version, Colors, Transparent BG

8) Artisan
Configuration (config/qrcode.php)
Troubleshooting: "the QR code won't scan"
The encoder output is standards-compliant, so a code that fails to scan is almost always a rendering or display problem. Check the following:
- Do not stretch the image. Keep the QR perfectly square. When embedding the SVG,
never force a non-square
width/heightin CSS. The SVG usespreserveAspectRatio='xMidYMid meet'so it letterboxes instead of distorting, but a container withobject-fitoverrides or fixed mismatched dimensions can still squash it. - Keep the quiet zone. Leave the default
marginof 4 modules. Don't crop the white border or place the code tight against other dark content. - Render big enough. Aim for at least ~3–4 device pixels per module. For higher
versions (longer data) increase
scaleor reduce the data length. - Preserve contrast. Dark foreground on a light background. Avoid low-contrast color pairs and never invert (light modules on dark background won't scan on most readers).
- Avoid post-processing. Anti-aliasing, JPEG compression of small images, or scaling to non-integer multiples blurs module edges. Prefer SVG, or PNG scaled by whole numbers.
- Shorten the payload. Very long URLs push the symbol to a high version with tiny
modules. Use a redirect/short link, or raise
scale.
Security & Performance
- Validate and limit input length to prevent excessive memory usage.
- Use SVG when possible for crisp scaling. GD/Imagick are optional for PNG.
- Avoid untrusted content injection when echoing inline HTML; prefer Response helpers.
