What is QR Code Generator?
A QR code (Quick Response code) is a two-dimensional barcode that stores data in a matrix of black and white squares. When scanned with a smartphone camera, QR codes can instantly open URLs, compose emails, dial phone numbers, connect to WiFi networks, or add contacts. Businesses use QR codes on marketing materials, product packaging, event tickets, and restaurant menus. QR codes can store up to 4,296 alphanumeric characters and include built-in error correction so they remain scannable even when partially damaged or obscured.
