QRCoder
A pure C# Open Source QR Code implementation
QRCoder is a simple library, written in C#.NET, which enables you to create QR codes. It hasn't any dependencies on other libraries and is available as .NET Framework and .NET Core PCL version on NuGet. Feel free to grab-up/fork the project and make it better! QRCoder is a .NET library, completely written in C#, which enables you to generate QR Codes as defined by ISO/IEC 18004. The main target of the QRCoder library is to deliver a small and easy-to-use solution, which has no dependencies to other libraries or network stacks. (Like QR Code generators which are relying on online services which makes them vulnerable/slow in some cases.) Although simplicity is one of the main goals, QRCoder is really flexible, in both "output formats" as well as in "payload types". Payload types? Yes, QRCoder brings its own "payload generator", which helps you to create a big list of different payload types to generate special QR codes like "WiFi QR Codes", "Girocodes", "SwissQRCodes" and many more. -

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) -

DScan
Uploads the content to IPFS and generates decentralized QR codes
DScan is a decentralized storage and file sharing tool. DScan allows you to quickly upload files as well as folders to IPFS by using web3.storage and receive a "decentralized QR code" with IPFS CID. Later you can customize and share the QR code or hosted gateway link with everyone for easy and decentralized file sharing. Because of web3.storage, the content can be accessed over IPFS without the user installing and setting up a local instance of Kubo. -

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 -

QPyDesk
Code editor and real-time QR code generator for QPython
QPyDesk is a code editor, and real-time QR code generator for QPython. It is a Python code editor with syntax highlighting that also generates the QR code that represents said code in real time. This application also allows you to print the generated QR code to distribute the created application. However, because QR codes have a limited storage capacity, if the code is very long, QPyDesk creates a QR code that is only valid while the application is running, that is, the QR code generated in this case is useless for distribute the application, but it is still useful to check the operation of the script while it is encoded from the computer. When these circumstances occur, QPyDesk notifies the user and disables the print button. QPyDesk gives dynamism during the development of applications for QPython / Android, since it takes advantage of the QPython QR code reader to work comfortably from the computer for the android device. -
