Definition of QR Codes
QR stands for “Quick Response”, and it is a type of barcode that contains information in a two-dimensional matrix.

Scanning a QR code has several advantages over manually entering information. QR codes are quick and easy to read, and they can store large amounts of data in a small space. This makes them ideal for sharing detailed information with customers or visitors in a short amount of time. Additionally, QR codes can be used to link to websites or other digital content, making it easier for users to access the information they need.
