The term "QR" stands for "Quick Response," which refers to a code that allows for quick access to information. The QR code is a 2D variant of the barcode, which was devised in 1994 by the Japanese firm Denso Wave. The QR Code is composed mostly of black and white pixel patterns. The maximum number of characters that may be encoded in a QR code is 4000. QR codes may be used to convey many types of information with users, such as website URLs, Skype meetings, Zoom meetings, phone numbers, and so on. Another question is how we can scan QR codes and get information from them. To read QR codes, there are free apps in app stores, and currently, practically all phones can read QR codes by default using the camera app. So all you have to do is open your smartphone's camera app and hover it over a QR code, and the phone will read it for you and conduct the desired activity, such as dialing a phone number if it has one, or passing it to your WhatsApp or phone contacts list if it has one.
