How QR Codes Work

QR (Quick Response) codes are a type of matrix barcode that can store various types of data. They consist of black squares arranged in a square grid on a white background.

Key Components

• Finder Patterns: Three squares in the corners help scanners locate the code
• Alignment Patterns: Help maintain code integrity when scanning
• Timing Patterns: Help determine the size of the data matrix
• Data Area: Contains the encoded information

Error Correction

QR codes use Reed-Solomon error correction to ensure readability even when partially damaged. Four levels are available:

• L (Low): 7% of codewords can be restored
• M (Medium): 15% of codewords can be restored
• Q (Quartile): 25% of codewords can be restored
• H (High): 30% of codewords can be restored
