Blue is a popular colour for branded QR codes in Vietnam, so this template fits business cards, brochures, packaging, and digital marketing materials.
The blue QR code template is a pre-configured, scannable design with gradient blue backgrounds, modern dot patterns, and a central logo area built on an ISO 18004-compliant structure. QR Code AI uses Reed-Solomon error correction to preserve readability when you embed a custom logo. You can adjust 50+ parameters, including blue shade, pixel style (7 options), marker shape (7 options), gradient intensity, and background effects.
Blue-themed QR codes work well for technology, finance, healthcare, and professional services, where blue signals trust and reliability. Businesses in Vietnam often place blue QR codes on business cards, slide decks, product packaging, and printed materials. QR Code AI supports dynamic QR codes (premium plans) with scan analytics such as location, device type, browser, OS, and referrer data.
You can add your company logo to the blue QR code template by uploading a PNG, JPG, or SVG file in QR Code AI to replace the default centre design. The logo sits in the QR code’s error-correction zone, where Reed-Solomon algorithms help keep scannability. You can fine-tune logo size, padding, and background shape, and match brand colours precisely using hex colour inputs.
The blue gradient template is available on the free plan in QR Code AI, with unlimited static QR code generation and basic customisation for colours, pixel styles, and marker shapes. Free-plan users can download PNG and SVG at full resolution. Premium plans unlock dynamic QR codes with editable URLs, scan analytics with location and device data, advanced visual effects, and WebP export.
To choose the right shade of blue, use QR Code AI’s preset blues from light sky blue to deep navy, or enter a hex colour for exact brand matching. Matching your primary brand colour keeps your QR code design consistent across print and digital. Darker blues usually scan more reliably on white backgrounds, while lighter blues can suit darker materials. The editor previews contrast in real time to optimise scannability.
