Understanding QR Codes
What is a QR Code?
A QR (Quick Response) code is a two-dimensional barcode invented by Denso Wave in 1994 for tracking automotive parts. Unlike traditional barcodes that store data horizontally, QR codes store information in both dimensions, enabling them to hold much more data—up to 4,296 alphanumeric characters. Today, they're ubiquitous: from restaurant menus to payment systems, from boarding passes to digital business cards.
Types of QR Code Content
The most common use. Direct scanners to websites, landing pages, or app download links.
Display messages, instructions, or information without requiring internet connection.
Share contact details instantly. One scan adds name, phone, email, and address to contacts.
Connect to WiFi without typing passwords. Great for homes, offices, and guest networks.
Pre-fill email addresses and subjects, or SMS numbers with messages ready to send.
Encode GPS coordinates to open in maps. Perfect for event venues and store locations.
How to Use This Tool
- Enter your content: Type the URL, text, or contact information you want to encode.
- Customize appearance: Choose colors, add a logo, and adjust size to match your brand.
- Preview your code: See how it looks in real-time as you make changes.
- Test before printing: Always scan your QR code with multiple devices to verify it works.
- Download and use: Export as PNG in your preferred resolution for print or digital use.
QR Code Best Practices
- •Maintain contrast: The code should stand out clearly from its background. Light on dark works, but classic black on white is most reliable.
- •Size matters: For print, ensure codes are at least 2cm x 2cm. Larger for scanning from a distance.
- •Add context: Include a call-to-action near the code: "Scan for menu" or "Scan to connect".
- •Use short URLs: Less data means simpler codes with better error correction. Use URL shorteners for long links.
⚠️ Security Note
QR codes can direct users to malicious websites. When generating codes, use URLs you control. When scanning others' codes, check the URL before proceeding. Modern phone cameras show the destination—verify it looks legitimate before tapping.
