What Are QR Codes?
QR (Quick Response) codes are two-dimensional barcodes that can store text, URLs, and other data in a pattern of black and white squares. They were invented in 1994 by Denso Wave for tracking automotive parts and have since become ubiquitous in marketing, payments, event tickets, restaurant menus, and personal sharing. Any smartphone camera can scan a QR code instantly.
QR Code Types Supported
This generator supports five common QR code types. URL codes open a website when scanned. Text codes display plain text. Email codes open a pre-filled email composition window. Phone codes initiate a phone call. Wi-Fi codes automatically connect the scanning device to a wireless network without manually entering the password — useful for sharing your home or office Wi-Fi with guests.
Tips for QR Code Usage
For printed materials, ensure the QR code is at least 2 × 2 centimeters (about 0.8 × 0.8 inches) for reliable scanning. Maintain high contrast between the QR code and its background — dark codes on light backgrounds work best. Always test your QR code with multiple devices before printing. Avoid placing QR codes on curved surfaces or in locations with poor lighting, as these conditions make scanning difficult.
