This library helps you generate QR codes in a jiffy. Makes use of bacon/bacon-qr-code to generate the matrix and khanamiryan/qrcode-detector-decoder for validating generated QR codes. Further extended with Twig extensions, generation routes, a factory and a Symfony bundle for easy installation and configuration. Different writers are provided to generate the QR code as PNG, SVG, EPS or in binary format.
Use Composer to install the library.
