What is a QR Code?
A QR code (Quick Response code) is a two-dimensional barcode that can store information and be scanned using a smartphone camera. Created in 1994 by Denso Wave, a Japanese company, QR codes have become ubiquitous in our daily lives - from restaurant menus to product packaging to business cards.
Unlike traditional barcodes that only store data horizontally, QR codes store information both horizontally and vertically, allowing them to hold significantly more data - up to 7,089 numeric characters or 4,296 alphanumeric characters.
Quick Fact: QR codes can store URLs, text, contact information, WiFi credentials, and much more - all accessible with a simple scan from any smartphone.

Remember: Ensure high contrast between foreground and background for optimal scannability.
Test and Download
Before using your QR code:
- Scan it with multiple devices to ensure it works
- Test with different QR scanner apps
- Verify it leads to the correct destination

Create QR Code Now →Types of QR Codes You Can Create
Understanding the different types of QR codes helps you choose the right one for your needs:
1. Static QR Codes
Content is permanently encoded in the QR code itself. Once created, the destination cannot be changed.
Best for: Permanent content, personal use, situations where tracking isn't needed
Pros: Never expire, work forever, no subscription needed, privacy-focused
Cons: Cannot edit destination, no analytics, must recreate if URL changes
2. Dynamic QR Codes
QR code redirects through a short URL that you can edit anytime, even after printing.
Best for: Marketing campaigns, evolving content, situations requiring analytics
Pros: Editable destination, track scans, A/B testing capability
Cons: Requires subscription, depends on service availability
3. Specialty QR Codes
Pre-formatted QR codes for specific purposes:
- WiFi QR Code: Instant network connection (Create WiFi QR)
- vCard QR Code: Digital business card that saves contacts instantly
- Calendar Event: Add events to calendar with one scan
- Payment QR: Accept payments via apps like PayPal or Venmo
- App Store: Direct users to download your app
Customizing Your QR Code
While basic black-and-white QR codes work perfectly, customization can help your QR code match your brand and stand out:
Color Customization
Change colors to match your brand identity, but follow these rules:
- Maintain high contrast (dark foreground on light background)
- Avoid light colors on light backgrounds
- Test scannability with multiple devices after customizing
- Minimum contrast ratio: 4:1 for optimal scannability
Adding Logos
Place your company logo in the center of the QR code to increase brand recognition:
- Logo should cover maximum 20% of QR code area
- Use high error correction (Level H) when adding logos
- Ensure logo has clear borders/padding
- Always test scannability after adding a logo
Error Correction Levels
Choose the right error correction for your use case:
- Level L (7%): Good for digital displays, large sizes
- Level M (15%): Standard for most applications
- Level Q (25%): Good for outdoor use, small sizes
- Level H (30%): Best for codes with logos, damaged environments
QR Code Best Practices
✓ DO
- Test on multiple devices before deploying
- Use high resolution for printing (at least 1024px)
- Include a call-to-action ("Scan to visit website")
- Ensure minimum 2cm x 2cm size for print
- Place QR codes at eye level when possible
- Provide context about what happens after scanning
- Check that destination is mobile-friendly
- Keep URLs short and clean
✗ DON'T
- Use on curved or textured surfaces
- Make QR codes too small (minimum 2cm x 2cm)
- Place in areas with poor lighting
- Use low-contrast color combinations
- Link to non-mobile-optimized pages
- Forget to test before mass printing
- Place too high or too low for easy scanning
- Assume everyone knows how to scan QR codes
Common Mistakes to Avoid
1. Not Testing Before Printing
The #1 mistake: printing thousands of QR codes without testing. Always scan with multiple devices and apps before mass production. A simple typo or wrong URL can waste your entire print run.
2. Using Low-Quality Images
Pixelated or blurry QR codes won't scan. For professional printing, use vector formats (SVG) or high-resolution PNG files (at least 1024px). For large-format printing (banners, billboards), go even higher - 2048px or larger.
3. Poor Color Choices
Yellow QR code on white background? Light blue on light gray? These won't scan. The rule is simple: high contrast. Dark foreground on light background, or vice versa. When in doubt, stick with black on white.
4. Broken or Dead Links
QR codes leading to 404 errors frustrate users. Double-check your URLs, ensure they work, and consider using dynamic QR codes for campaigns where you might need to change the destination later. If you're using static QR codes, make absolutely certain the destination won't change.
5. No Call-to-Action
Don't assume people will scan just because there's a QR code. Add clear instructions and value proposition: "Scan to get 20% off", "Scan for menu", "Scan to connect to WiFi". Tell users what they'll get when they scan.
6. Placing in Inaccessible Locations
QR codes on moving vehicles, in dim lighting, behind glass with reflections, or too high/low to comfortably scan - all common mistakes. Consider the scanning experience: distance, angle, lighting, and ease of access.
Frequently Asked Questions
How much does it cost to create a QR code?
Creating basic QR codes is completely free with tools like QRQuick. There's no limit to how many you can create, and no watermarks or restrictions. Dynamic QR codes with analytics typically require a paid subscription ($5-20/month), but static QR codes are free forever.
Do QR codes expire?
Static QR codes never expire. They encode the destination directly, so they'll work forever as long as the destination (like a website) remains active. Dynamic QR codes depend on the service provider - if you stop paying or the service shuts down, the QR code will stop working.
Can I edit a QR code after creating it?
Static QR codes cannot be edited once created - you need to generate a new one. Dynamic QR codes CAN be edited because they redirect through a URL that you control. This is why dynamic QR codes are popular for marketing campaigns where flexibility is needed.
What's the best size for a QR code?
Minimum size is 2cm x 2cm (0.8" x 0.8") for close-range scanning. For posters or displays viewed from distance, use larger sizes - formula is roughly: size = distance ÷ 10. For a poster viewed from 2 meters away, make the QR code at least 20cm x 20cm.
Can QR codes work without internet?
Scanning a QR code doesn't require internet, but accessing the destination usually does. Exceptions include QR codes containing plain text, contact information (vCard), or WiFi credentials - these can be processed offline. URL-based QR codes need internet to load the destination page.
Are QR codes safe to scan?
Generally yes, but use caution. Most smartphones show the destination URL before opening it, giving you a chance to verify it's legitimate. Don't scan QR codes from untrusted sources, check the preview URL before proceeding, and be wary of codes that initiate downloads or ask for personal information immediately.
How do I scan a QR code?
Modern smartphones have built-in QR scanning. On iPhone, open the Camera app and point at the QR code - a notification will appear. On Android, use the Camera app or Google Lens. Older phones may need a dedicated QR scanner app from the app store.
Can I use colors in QR codes?
Yes! You can customize both foreground and background colors. The key requirement is sufficient contrast - aim for a contrast ratio of at least 4:1. Dark blue on white works great, as does black on yellow. Avoid combinations like light gray on white or yellow on white.
