What are QR Codes?
QR (Quick Response) codes are two-dimensional barcodes that can store much more information than traditional barcodes. They were invented in 1994 by Denso Wave, a subsidiary of Toyota, to track automotive parts during manufacturing. Today, QR codes have evolved into powerful tools for bridging the gap between physical and digital experiences.
Modern QR codes can store various types of data including URLs, text, contact information, Wi-Fi credentials, and even small amounts of binary data. They're designed to be quickly scanned by smartphones and other devices, making them ideal for marketing, business operations, and personal use. Our tool combines advanced QR code generation with customization options for professional results.
