Definition of QR Codes
QR Code (Quick Response Code) is a type of two-dimensional barcode that can store a considerable amount of information and can be scanned digitally using smartphones. It consists of a matrix of black squares arranged in a square grid on a white background, allowing it to be scanned quickly from any angle, unlike traditional one-dimensional barcodes.

- Data Matrix: A more complex type of 2D barcode that’s square shaped, often used in manufacturing and aerospace. Think QR Code with an mini-architecture degree!
