Understanding What a QR Code Scanner Does

Before you start scanning, it’s helpful to know what a QR code scanner actually is and how it works in everyday use.

Introduction to QR Code Technology

QR codes are two-dimensional barcodes that store information like URLs, contact details, or payment links. A QR code scanner online reads these patterns instantly, turning them into usable information in seconds.

How a QR Scanner Works

When you scan with a QR code scanner from image or through your camera, the tool reads the black-and-white pixel pattern, interprets it, and displays the decoded data in a readable format.
