. A barcode is a machine-readable optical label that contains information about the item to which it is attached. QR code is said to store over 4000 alphanumeric characters.
A QR code uses four standardized encoding modes (numeric, alphanumeric, byte/binary, and kanji) to store data efficiently,
extensions may also be used.
It consists of black squares
arranged in a square grid on a white background, which can be read by an imaging device and processed using Reed–Solomon error correction
until the image can be appropriately interpreted. The required data is then extracted from patterns that are present in both horizontal and vertical components
of the image. QR codes often contain data for a locator, identifier, or tracke
r that points to a website or application.
