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. -

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) -

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 -

QR Code Generator

I digitally sign some files in my releases.
