QR Code Technology and Standards
QR (Quick Response) codes are two-dimensional matrix barcodes that store information in both horizontal and vertical dimensions, enabling significantly more data capacity than traditional linear barcodes. These codes can contain up to 7,089 numeric characters or 4,296 alphanumeric characters, making them ideal for storing complex information like URLs, contact details, and structured data.
QR codes incorporate error correction capabilities that allow successful scanning even when up to 30% of the code is damaged or obscured. This robust design ensures reliable data retrieval in various environmental conditions and makes QR codes suitable for outdoor advertising, product packaging, and industrial applications where wear and tear might occur.
