Abstract

Quick-response (QR) codes are widely used for information transmission. However, their black-and-white dot structure often lacks visual appeal. Therefore, we developed novel graphic QR codes that remove traditional corner finder patterns and conceal data within redesigned modules. These codes can be scanned, positioned, and decoded directly in software, while paper-based versions can be instantly decoded by overlaying a transparency with printed finder patterns. Experimental results across varying grayscale levels and devices confirmed reliable readability. The proposed QR codes provide enhanced esthetics and security, offering a new direction for future QR code applications.
