What is a QR Code and How to Use It?
What is a QR Code?
QR code (Quick Response Code) is a two-dimensional barcode system developed in 1994 by the Japanese company Denso Wave.
Compared to traditional barcodes, QR codes can store much more data and have become an integral part of everyday life with the advancement of mobile technology.
Today, QR codes are used globally in various industries, enabling quick access to information with a simple scan.
How Do QR Codes Work?
QR codes carry binary data arranged as black and white squares in a grid. When a QR code is scanned, the following steps occur:
- Scanning: A camera or QR reader detects the code.
- Recognition: Software analyzes position markers.
- Decoding: The data inside the code is read.
- Action: The data opens in the appropriate app or browser.
💡 Modern smartphone cameras can recognize QR codes without the need for a separate app.
