What is a QR Code?

QR (Quick Response) codes are two-dimensional barcodes that store information in a pattern of black and white squares. Invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become ubiquitous for sharing URLs, contact information, WiFi passwords, and payment details. They can store up to 4,296 alphanumeric characters.

QR Code Best Practices

Ensure sufficient size for reliable scanning (minimum 2cm x 2cm for close-range, larger for distance). Maintain high contrast between foreground and background colors. Include a quiet zone (white border) around the code. Test the QR code with multiple scanning apps before printing. Always link to mobile-friendly destinations.

QR Code Use Cases

Businesses use QR codes for: restaurant menus, contactless payments, marketing materials (linking to websites, videos, or social media), event tickets, product packaging (linking to instructions or reviews), business cards (vCard format), WiFi sharing (auto-connect), and inventory management.

QR Code Error Correction

QR codes include built-in error correction that allows them to be read even when partially damaged or obscured. There are four levels: Low (7% recovery), Medium (15%), Quartile (25%), and High (30%). Higher error correction means more data redundancy but larger QR codes. Medium is the standard for most applications.
