Giữ thương hiệu mà không giảm tỷ lệ quét.
Intro
Logos help branding but can reduce scan reliability if they cover too much area.
Preparation
Decide logo size and background treatment before generating the final code.
Steps
Keep logos within 15–20% of the QR area, use Q/H error correction, and ensure contrast.
Example
Reducing logo size and increasing QR size restored scan rates on brand stickers.
Mistakes
Oversized logos and low‑contrast colors blur module boundaries.

Operations

Tips
Grow the QR size rather than the logo. Always test on the final medium.
FAQ
Must the logo be centered?
Center placement is safest; avoid edges and timing patterns.
Which logo colors work best?
High contrast against the QR modules works best.
