Why QR64Code is different
Input transparency
We explain which inputs stay on your device and which third-party technologies may process separate usage data.
Measurable output
Results include verifiable values such as size, algorithm, format, or time unit.
Sourced explanations
Security and format claims link to standards, RFCs, and official technical documentation.
