A PHP QR Code generator and reader with a user-friendly API
chillerlan/php-qrcode is a modern, flexible PHP library for generating QR codes. It supports various customization options such as size, encoding, error correction, and logo embedding. The library is PSR-compliant and built for ease of use in modern PHP projects, making it suitable for generating QR codes in web apps, receipts, and authentication systems.
Most QR codes are just text. When scanned with a USB reader, the reader just types out the text really quickly.
It's difficult to type in a 55-character bitlocker key. This tool will create a QR code from a bitlocker key so you can plug a 2D barcode scanner into the affected computer, then scan the picture from the program.
There's a section to allow you to create a QR with some cmd code to simplify the unlock and even delete a file.
SlowQR allows to scan QR codes from images.
Some manual interaction for distorted codes is possible.
Due to missing hardware-accelerated drawing support,
automatic recognition may be slow, hence the name.
New features:
- creation/editing of QR codes.
- support of images with perspective
- optional experimental offscreen hardware acceleration (via openGL 2-FBOs)
