What are QR Codes?

QR (Quick Response) codes are two-dimensional barcodes that can store various types of data. They were invented in 1994 and have become ubiquitous in modern life. Unlike traditional barcodes, QR codes can store much more data and can be read from any direction.

QR Code Uses

• URL Sharing: Share website links and social media profiles
• WiFi Access: Allow users to connect to WiFi networks by scanning
• Business Cards: Add contact information to digital business cards
• Product Information: Link to product details and specifications
• Event Information: Share event details and registration links
• Payment Information: Enable mobile payments and transactions

Format Options

PNG Format: Best quality with lossless compression. Ideal for most uses including print and digital displays. Supports transparency and works with all devices.

SVG Format: Vector format that scales infinitely without quality loss. Perfect for large-scale printing and when you need to resize the QR code without losing quality.

Size Recommendations

• Business Cards: 200-300px for crisp scanning at close range
• Print Materials: 300-500px for flyers, posters, and brochures
• Large Displays: 500-1000px for billboards and large screens
• Digital Use: 200-400px for websites and digital documents

Best Practices

• Test QR codes with multiple smartphone cameras before final use
• Ensure adequate contrast between the QR code and background
• Leave enough white space (quiet zone) around the QR code
• Use appropriate size for the intended scanning distance
• Consider error correction levels for environments where codes might get damaged
