Teachers can place these codes in handouts or presentations, creating bridges between physical and digital learning environments while tracking engagement with specific resources.
Frequently Asked Questions About QR Codes
What's the difference between various QR code error correction levels?
Error correction levels in QR codes determine how much damage the code can sustain while remaining scannable:
• Level L (Low): Recovers up to 7% damage, creating the most compact codes ideal for controlled environments
• Level M (Medium): Handles up to 15% damage, providing a good balance for most standard applications
• Level Q (Quartile): Withstands up to 25% damage, recommended for industrial uses or outdoor display
• Level H (High): Tolerates up to 30% damage, best for harsh environments or when adding logos
Higher correction levels create more complex QR code patterns with additional redundancy, which makes the codes slightly larger but significantly more reliable in challenging conditions or when customized with colors or logos.

Can I add a logo to my QR code without breaking its functionality?
Yes, you can add logos to your QR codes while maintaining scannability by following these guidelines:
1. Use a higher error correction level (preferably H) when creating custom QR codes with logos
2. Keep your logo relatively small, ideally covering no more than 30% of the central area
3. Ensure the logo has sufficient contrast with the QR code colors
4. Avoid placing the logo over the three position detection patterns (the squares in the corners)
Our QR code generator automatically adjusts the code's data density when you add a logo, ensuring the resulting code remains fully functional. After adding a logo, always test your QR code with multiple devices to verify it scans correctly in various conditions.

What information can I encode in a QR code?
QR codes can encode various types of information, making them extremely versatile:
• Website URLs: Direct scanners to specific web pages, landing pages, or online resources
• Plain text: Store messages, identifiers, or any alphanumeric information (up to about 4,000 characters)
• Contact information (vCard/meCard): Share complete contact details that can be saved directly to a phone's contacts
• WiFi network credentials: Allow instant connection to WiFi networks without typing passwords
• Phone numbers: Initiate calls when scanned
• SMS messages: Open pre-populated text messages
• Email addresses: Start new emails to specified recipients
• Geographic locations: Open map applications to specific coordinates

How large should I print QR codes for optimal scanning?
The optimal size for printing QR codes depends on the scanning distance:
• Minimum size: 2 × 2 cm (0.8 × 0.8 inches) for close scanning
• Standard recommendation: 3 × 3 cm (1.2 × 1.2 inches) for typical use cases
• Scanning from 1-2 meters away: 10 × 10 cm (4 × 4 inches) or larger
• Billboard or distant scanning: At least 30 × 30 cm (12 × 12 inches)
A general rule of thumb is that the printed QR code should measure at least 1/10th of the scanning distance. Additionally, always include a quiet zone (empty margin) around the code measuring at least four times the width of a single module (the smallest square in the code).
Our QR code generator produces high-resolution SVG files that can be scaled to any size without losing quality, ensuring your codes remain crisp and scannable regardless of the printed dimensions.
