Decimen Optical Transfer
Fountain-coded QR file transfer
Decimen Optical Transfer is a browser-based proof of concept for moving files between devices through animated QR codes. A sending screen continuously displays encoded frames while a receiving camera captures enough of them to reconstruct the original payload. The system requires no direct network path, pairing process, native application, or permission beyond camera access. Fountain coding makes the stream tolerant of missed, blurred, duplicated, and out-of-order frames without requesting retransmission. Each QR frame includes session and file metadata, allowing a receiver to join an active stream or reset when a new session begins. QR decoding runs through zxing-cpp compiled to WebAssembly and uses workers to process camera frames efficiently. Configurable settings control payload size, transmission speed, QR density, capture resolution, and worker count, while a final hash verifies the recovered file. -

ZXingLite
Simplified version of ZXing, optimized to scan codes to generate QR
ZXingLite for Android is a simplified and extremely fast version of ZXing. Based on the ZXing library, it optimizes the functions of scanning codes and generating QR codes/barcodes. The scanning interface fully supports customization, and one line of code can also use the default scanning function. In short, everything you want is here. By inheriting CaptureActivity or CaptureFragment and customizing the layout. (Applicable to most scenarios, and you don’t need to care about the code scanning related logic, you need to override the getLayoutId method when customizing the layout) Implementation examples: CustomCaptureActivity and QRCodeActivity. Instantiate a CameraScan in the Activity or Fragment of your project. (Applicable to use when you want to write interactive logic on the code scanning interface, and cannot directly or indirectly inherit CaptureActivity or CaptureFragment due to project architecture or other reasons) -

QRTxt
QR Code Generator
QRTxt is just a personal project. It's a very simple QR code generator. I had two major goals in creating this project: - Make it simple and user friendly - Provide useful feedback instead of just crashing without warning if a user tries to enter more characters than a QR code supports. I digitally sign some files in my releases. If you'd like to verify those signatures, you can find my PGP/GPG keys at: https://marcusadams.me/keys.html If you'd like to donate there's several ways to do so: PayPal: https://paypal.me/gerowen Bitcoin (BTC): bc1q86c5j7wvf6cw78tf8x3szxy5gnxg4gj8mw4sy2 Monero (XMR): 42ho3m9tJsobZwQDsFTk92ENdWAYk2zL8Qp42m7pKmfWE7jzei7Fwrs87MMXUTCVifjZZiStt3E7c5tmYa9qNxAf3MbY7rD -

BDE QR Generator
Offline QR code generator for BDE
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. You can keep concatenating with &&. The screenshots section should show you everything you need to start using it. Crucially, this does not use any web api calls. It can run offline. I'm not a coder so this isn't error handled anywhere near as well as it should. Source is in the files section. Built on QRCoder by Raffael Herrmann, released under MIT license. https://github.com/codebude/QRCode -

qrcode generation standalone (doesn't depend on external services)
jquery-qrcode is a small jQuery plugin for generating QR codes directly inside the browser. It lets developers add QR code output to a webpage without calling an external service or downloading a remote image. The plugin is designed to be lightweight, with a minified and compressed footprint of less than 4 KB. Its basic usage is simple: include the script, create a container element, and call the QR code method with text or options. Developers can configure dimensions such as width and height when generating a code. It is best suited for older jQuery-based sites, simple web utilities, landing pages, and legacy projects that need fast client-side QR generation.
