Meaning – The term scan code, refers to a code that the keyboard generates when a keyis pressed. Every key on a keyboard has a unique scan code associated with it.
It is also referred to as a QR code.
It can be scanned using a QR scanner or a smartphone with a built-in camera. Once scanned, software on the device converts the dots within the code into numbers or a string of characters.
All QR codes have a square shape and include three square outlines in the bottom-left, top-left, and top-right corners. These square outlines define the orientation of the code. The dots within the QR code contain format and version information as well as the content itself.
Example of usage – “Standard UPC scanners use a laser to scan barcodes, which means they typically cannot scan a UPC from a screen (like a smartphone). QR scanners, however, are designed to capture 2D images printed on paper or displayed on a screen.”
