A QR (Quick Response) code is a two-dimensional barcode that stores information in a pattern of black and white squares. Originally invented in 1994 by Denso Wave for the automotive industry, QR codes have since become ubiquitous in marketing, retail, hospitality, and everyday life. They can be scanned by any smartphone camera to instantly access websites, contact information, WiFi networks, and more.
How QR Codes Work
QR codes encode data using a matrix of dark and light modules arranged in a square grid. The three large squares in the corners help scanners detect the code's orientation, while the smaller patterns encode the actual data. QR codes include error correction, meaning they can still be read even if partially damaged or obscured — making them ideal for printed materials.
Static vs Dynamic QR Codes
Static QR codes encode data directly. Once created, the destination cannot be changed. They are great for permanent information like WiFi passwords or contact cards.
Dynamic QR codes use a short URL that redirects to your destination. You can update the destination anytime without reprinting the code. They also enable scan tracking, analytics, A/B testing, and smart routing.
