Frequently Asked Questions About QR Codes
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores data such as URLs, text, contact information, or WiFi credentials. When scanned with a smartphone camera, it instantly directs the user to the encoded content.
What is the difference between static and dynamic QR codes?
Static QR codes encode data directly and cannot be changed after creation. Dynamic QR codes use a short redirect URL, allowing you to update the destination, track scans, and add features like password protection without reprinting the code.
Are QR codes free to create?
Basic static QR codes are free to create on most platforms including QRLynx. Dynamic QR codes with tracking, analytics, and advanced features are available on paid plans, with QRLynx offering a free Starter tier that includes up to 3 dynamic codes.
How do I track QR code scans?
Dynamic QR codes automatically track every scan. QRLynx provides real-time analytics including total scans, unique visitors, geographic location, device type, operating system, and time-of-day patterns.
What size should a QR code be for printing?
The minimum recommended size is 2 x 2 cm (0.8 x 0.8 inches) for close-range scanning like business cards. For posters, use at least 10 x 10 cm. For billboards, calculate based on viewing distance — generally 10:1 ratio of distance to QR code width.
Can I customize the appearance of my QR code?
Yes. QRLynx lets you change colors, add your logo, choose from multiple patterns and corner styles, and apply gradient effects. Always maintain sufficient contrast between the foreground and background for reliable scanning.
Do QR codes expire?
Static QR codes never expire since the data is embedded directly. Dynamic QR codes remain active as long as the hosting service is operational. QRLynx also offers optional expiry rules that let you deactivate a code after a set date or scan count.
Are QR codes secure?
QR codes themselves are safe, but they can link to malicious websites. QRLynx scans every destination URL for phishing and malware using automated security checks and assigns a risk score before the code is created.
How many types of QR codes are there?
QRLynx supports 42 QR code types including URL, vCard, WiFi, email, SMS, WhatsApp, PDF, event, location, PayPal, social media profiles, app store links, and many more specialized formats.
Can I change where my QR code points after printing?
Yes, if you created a dynamic QR code. You can update the destination URL, change the linked content, or swap the entire QR code type at any time from your QRLynx dashboard without needing to reprint the physical code.
