What is a QR Code?
A QR code is a matrix barcode that can store a large amount of information. Its design allows for fast reading and high error correction, making it a reliable way to share data digitally.
How Do They Work?
QR codes store data in a pattern of black squares on a white background. A QR code scanner, like the one on your smartphone, can read this pattern and decode the information, which can then trigger an action like opening a website.
