What Is A QR Code?
Quick Response (QR) codes are two-dimensional barcodes that store information in a machine-readable format. Developed in 1994 by the Japanese company Denso Wave, QR codes have evolved to become a ubiquitous element in marketing, product tracking, and mobile payments. Unlike traditional barcodes, QR codes can hold a significant amount of data, including:
- URLs
- Contact information
- Product details
- Wi-Fi network credentials
When you scan a QR code, your camera or scanner decodes the visual information, allowing you to access the stored content instantly.
How QR Codes Work
