Understanding QR Codes
QR codes, short for Quick Response codes, are two-dimensional barcodes that contain encoded information. These codes are designed to be easily scanned and decoded using a QR code scanner or reader. They can store various types of data, including text, URLs, contact information, and more.
What are QR Codes?
QR codes are square-shaped codes that consist of black squares arranged on a white background. They are similar to traditional barcodes but can store much more information. QR codes use a matrix format, allowing them to store data both horizontally and vertically, resulting in a higher data capacity.
To scan a QR code, you need a QR code scanner or reader, which can be a dedicated app on your smartphone or a built-in feature of your smartphone’s camera. These scanners capture the QR code image, decode the information, and provide the relevant output, such as opening a website, displaying text, or initiating a phone call.
