- Colour-coded visualisation of Finder Patterns, Timing Patterns, Format Information, Version Information, Data modules, and ECC (Error Correction Code) modules
- Display of mask patterns and the unmasked bit matrix
- Detailed QR metadata: version, error correction level, mask pattern, size, number of data codewords, and number of ECC (Error Correction Code) codewords
Recommended For
- Students and engineers who want to learn QR code specifications and internal structure
- Developers who need to inspect or debug their own QR libraries or decoders
- Anyone who wants to go beyond simple 'reading' and truly understand how QR codes work
