QR codes have become ubiquitous in marketing, payments, menus, ticketing, and information sharing. They bridge the physical and digital worlds by letting users instantly access online content with their phone camera.
For businesses, QR codes provide trackable links to websites, reduce printing costs for menus and brochures, and enable contactless payments and check-ins.
QR codes need to be at least 2x2 cm (0.8x0.8 inches) for reliable scanning. Smaller sizes may not scan on all devices.
For printed materials, use high error correction (H level). This ensures readability even with minor damage or dirt.
Always scan your QR code with multiple devices before mass printing. A non-functional QR code wastes printing costs.
If your QR code links to a website, ensure it is mobile-responsive since most QR scans happen on smartphones.
QR (Quick Response) code is a two-dimensional barcode that stores data readable by smartphones. It can contain URLs, text, contact info, WiFi credentials, and more.
A QR code can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes. Practical limit for URLs is about 2,000 characters.
Static QR codes never expire as they contain the data directly. Dynamic QR codes (which redirect through a service) may expire if the service is discontinued.
Yes, QR codes have built-in error correction (up to 30% of the code can be damaged/covered). This allows adding logos, changing colors, and customizing the design.
SVG is best for print as it scales infinitely without quality loss. For digital use, PNG at 300+ pixels is sufficient.
