QR & Barcodes Architecture & Usage Guide
Vector Scalability vs Pixelated Raster QR Codes
Standard raster QR codes pixelate and blur when enlarged for billboard printing or retail displays. KitWharf generates pure mathematical SVG vector code, ensuring your QR codes remain razor-sharp whether printed on a business card or an exhibition banner.
Error Correction and Logo Embedding
Our generator supports Reed-Solomon Error Correction Level H (up to 30% data recovery), allowing you to place custom corporate logos in the center of the code without impairing scanning readability by modern iOS and Android camera apps.
