What are QR Codes?
QR (Quick Response) codes are two-dimensional barcodes that can store various types of information like URLs, text, contact details, WiFi credentials, and more. Invented in 1994 by Denso Wave for tracking automotive parts, QR codes have become ubiquitous in marketing, payments, product tracking, and contactless information sharing. They can be scanned using smartphone cameras and QR code reader apps to instantly access the encoded data.
Common Use Cases
Marketing & Advertising
Add QR codes to posters, flyers, business cards, and product packaging. Direct customers to landing pages, promotions, product information, or social media profiles. Track scan metrics to measure campaign effectiveness.
Contactless Payments
Enable mobile payments with payment app QR codes. Popular in Asia and growing globally, QR payment codes allow customers to pay by scanning with their phones, reducing cash handling and speeding up transactions.
Digital Menus & Information
Restaurants use QR codes for contactless menus. Museums display them for exhibit information. Hotels provide them for check-in and amenities. Reduces physical contact and printing costs while providing detailed information.
Event Management
Generate unique QR codes for event tickets, conference badges, and access control. Attendees scan codes for check-in, session access, and networking. Simplifies registration and reduces fraud with unique codes.
Frequently Asked Questions
How do I scan a QR code?
Modern smartphones (iPhone iOS 11+, Android) have built-in QR code scanning in their camera apps. Simply open your camera, point it at the QR code, and tap the notification that appears. For older phones, download a free QR code reader app from your app store.
What can I encode in a QR code?
QR codes can store URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS messages, WiFi credentials, vCard contact info, GPS coordinates, calendar events, and app store links. Maximum capacity is around 4,296 alphanumeric characters, though shorter content scans more reliably.
Do QR codes expire?
Static QR codes (like these) never expire—they contain the data directly. However, if the QR code points to a URL and that website goes down, the code won't work. Dynamic QR codes (generated by paid services) can be updated and tracked but may expire if you stop paying for the service.
Can I customize QR code colors?
Yes! You can change foreground and background colors as shown in this tool. Ensure sufficient contrast (dark foreground, light background recommended) for reliable scanning. Avoid low-contrast combinations like yellow on white or dark blue on black.
What size should my QR code be?
For print: minimum 2cm × 2cm (0.8" × 0.8"). For billboards: much larger relative to viewing distance. Rule of thumb: QR code size should be at least 10% of the scanning distance. Test scanning from the expected distance. Include a "quiet zone" (empty space) around the code.
Are QR codes secure?
QR codes themselves are just data containers. Security depends on what they link to. Malicious QR codes can link to phishing sites or malware. Always verify the URL preview before opening links. Use trusted QR codes from reliable sources. Some QR readers have URL preview and security scanning features.
