Why use QR codes?

• Contactless sharing: No typing — just scan and go.
• Track engagement: Use trackable URLs to measure scans.
• Save space: Replace long URLs with a compact square.
• Professional look: Clean, modern way to share information.
• Versatile: Works on any surface — paper, screens, products, clothing.
• Universal: Any smartphone can scan QR codes natively.

QR code types

URL / Website

Link to any webpage, landing page, or online resource. Most common use case.

Example: https://example.com/promo

Plain text

Share messages, instructions, or information that appears directly after scanning.

Example: "Welcome to our event! Check in at booth #5"

Email

Pre-fill an email with recipient, subject, and body text.

Example: mailto:support@example.com?subject=Question

Phone number

One-tap calling — perfect for business cards and support materials.

Example: tel:+1234567890

SMS

Pre-filled text message ready to send.

Example: sms:+1234567890?body=Hello

Wi-Fi credentials

Share network access without revealing the password visually.

Format: SSID, password, and encryption type (WPA/WEP)

vCard (Contact)

Share complete contact information — name, phone, email, address, company.

Use case: Business cards, email signatures, event badges

Customization options

Colors

• Foreground: The dark squares (default: black)
• Background: The light area (default: white)
• Contrast matters: Ensure scanners can read it (avoid low contrast)

Size

• Small (256px): Digital use, websites, emails
• Medium (512px): Social media, presentations
• Large (1024px): Print materials, posters, banners
• SVG: Infinite scalability for professional printing

Error correction

QR codes have built-in redundancy to work even if partially damaged:

• Low (7%): Smallest file size, less damage tolerance
• Medium (15%): Balanced — recommended for most uses
• Quartile (25%): Good for outdoor or worn surfaces
• High (30%): Maximum durability, larger code size

Higher correction = larger QR code but more reliable scanning.

Best practices

Design tips

• High contrast: Black on white works best — avoid pastels or low contrast
• Test before printing: Scan with multiple devices and apps
• Add context: Include "Scan me" text or an icon nearby
• Size matters: Minimum 2×2 cm (0.8×0.8 in) for reliable scanning
• Quiet zone: Leave white space around the code (at least 4 modules wide)

Content tips

• Keep URLs short: Use a URL shortener for cleaner codes
• Test the destination: Ensure links work and are mobile-friendly
• Use HTTPS: Secure links build trust and work better
• Avoid special characters: Stick to standard text when possible
• Update carefully: QR codes are static — you can't change them after printing

Placement tips

• Eye level: Place codes where people naturally look
• Good lighting: Avoid shadows and glare
• Flat surfaces: Curved or wrinkled surfaces are harder to scan
• Accessible: Ensure people can get close enough to scan
• Call to action: Tell people what they'll get by scanning

Common use cases

Marketing: Link to promotions, product pages, or video content on flyers and ads.

Events: Tickets, check-in, schedules, and feedback forms.

Restaurants: Digital menus, ordering systems, and payment links.
