A QR code is a type of two-dimensional barcode that can be read using a smartphone camera. QR codes are often used to provide people with information about a particular product or service, or to direct them to a website.
To generate a QR code, you need to use a QR code generator. There are many free online QR code generators available, such as QRCode Monkey and GoQR. Simply enter the data you want to encode into the generator and it will create a QR code for you. You can then download or print the QR code for use.
When scanning a QR code, it is important to make sure that your phone’s camera is focused correctly. The generated codes are usually very small, so it can be easy for the camera to miss them if it’s not in focus. Once you have your camera focused on the code, hold down the shutter button until the scan is complete. Your phone should then display the information encoded in the QR code.
