What Are QR Codes and Why Use Them?
QR codes (Quick Response codes) are two-dimensional barcodes that can store various types of data. When scanned with a smartphone camera, they instantly link users to websites, contact information, WiFi networks, and more.
In 2026, QR codes have become essential for:
- Businesses – Share website links, contact info, and promotions
- Events – Tickets, registration, and attendee engagement
- Restaurants – Digital menus and ordering systems
- Personal use – WiFi sharing, vCards, and social profiles
Types of QR Codes You Can Create
URL QR Codes
Link directly to any website, landing page, or online resource. Perfect for business cards, flyers, and product packaging.
WiFi QR Codes
Share your WiFi network credentials without typing complex passwords. Guests simply scan the code to connect automatically.
Contact (vCard) QR Codes
Share your complete contact information—name, phone, email, address—that saves directly to someone's phone contacts.
Email QR Codes
Pre-fill an email address and subject line. Great for customer feedback, support requests, and newsletter signups.
SMS QR Codes

Size Matters
For print materials, your QR code should be at least 2cm × 2cm (about 0.8 inches). The scanning distance is typically 10× the size of the code—a 2cm code can be scanned from about 20cm away.
Color Contrast
Maintain high contrast between your foreground and background colors. Dark codes on light backgrounds work best. Avoid yellow or light colors as the foreground—they're hard to scan.
Test Before Printing
Always test your QR code with multiple devices before printing large quantities. Different phones have different camera capabilities.
Don't Overcrowd
The more data a QR code contains, the denser (and harder to scan) it becomes. For long URLs, consider using a URL shortener first.
Free vs. Paid QR Code Generators
Most paid QR code services offer features like:
- Tracking and analytics (scan counts, locations)
