Frequently Asked Questions

What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit value used to identify resources. Version 4 UUIDs are randomly generated and have an extremely low probability of collision.

What is error correction?

Error correction allows a QR code to be scanned even if it is partially damaged or obscured. Higher levels (Q, H) add more redundancy so the code remains readable even if up to 25–30% is covered.

What is the difference between PNG and SVG?

PNG is a raster image — best for web and social sharing. SVG is a vector format — scales to any size without loss of quality, ideal for print.
