What is the Full Form of the QR Code?
QR code stands for Quick Response Code. They contain information in encoded form. Since QR codes allow one to access information both horizontally and vertically, they are faster than the traditional bar codes. This is essentially why they are called ‘Quick Response‘ codes. QR codes contain data related to an item or act as a tracker or locator to point to a particular website or application. The encodings that are often used in a QR code are numeric, alphanumeric, byte, and Kanji.

Ever opened WhatsApp on your PC or Laptop by scanning a black square box that seems to be colored unevenly in pixels? Well, that square box is nothing but a QR code. QR code is a 2-Dimensional bar code in the form of a matrix. It is like a label that can be read by machines to fetch the needed information they contain. Just like a barcode, which is 1-dimensional, is read using a scanner, a QR code can be scanned using our phones.
