What is QR Code?
QR code (Quick Response Code) is a two-dimensional matrix barcode that is readable by QR scanners and smartphones. It can store a large amount of data, including text, URL, and other types of information, and is often used for mobile payment systems, product tracking, and marketing. QR codes provide a fast and convenient way to access information quickly and easily.
how do qr codes work ?
QR codes work by encoding data into a pattern of black and white squares arranged in a specific way. This pattern is read by a QR code scanner or smartphone camera using image recognition technology. The scanner decodes the pattern and converts it back into the original information.
The data is stored in the QR code in a way that allows it to be read in any direction, which makes it convenient for people to scan the code quickly and easily. The black and white pattern also provides redundancy, which makes the code more resilient to damage and improves the chances of a successful scan.
Once the QR code is scanned, the information is displayed on the device, typically as text or a website link. This allows people to access the information quickly and easily, without having to manually enter it into their device.
