Quick Response (QR) codes are 2D matrix symbologies composed of square black modules arranged on a white grid. The matrix architecture includes three distinct concentric square finder patterns positioned at the corners, allowing optical cameras and laser scanners to detect code orientation and size rapidly regardless of scanning angle.
Data reliability is powered by Reed-Solomon Error Correction algorithms across four standardized tolerance tiers:
• Low (L): $7\%$ data restoration capability.
• Medium (M): $15\%$ data restoration capability.
• Quartile (Q): $25\%$ data restoration capability.
• High (H): $30\%$ data restoration capability.
For maximum scannability, QR codes require a Quiet Zone (a blank border margin around the perimeter) of at least 4 module widths. High luminance contrast between foreground modules and the background fill ensures rapid camera autofocus and decoding accuracy.
