QR Code Full Form

What Is the Full Form of the QR Code?

The full form of the QR Code is Quick Response Code. It is a trademark or a form of a 2D bar code containing a dot matrix. It was first developed by the Japanese automotive company Denso Wave in 1994 in Japan to monitor vehicles during development. Later, due to its easy readability and high storage space compared to conventional UPC barcodes, it became famous outside of the automotive sector.

  • A QR code represents a black square with a white background organised in a square grid.
  • An imaging system such as a telescope, smartphone with a built-in camera, QR reader, and so on. can interpret this both vertically and horizontally.
  • We may claim it is a machine-readable optical label that holds the data with which it is connected about an object, item, or product.
  • The imaging device transforms the dots inside the code into numbers or a group of characters upon scanning.
  • Scanning a QR code with your smartphone, for instance, may enable a URL in the web browser of your phone.
  • The QR codes are in the format of a square shape that determines the code orientation and allows each code to be unique.
  • No two QR codes could have a similar pattern.

Benefits of QR Code

There are two significant benefits of the QR code over conventional UPCs.

  1. QR code contains significantly more information because they are two dimensional UPC than one-dimensional UPC.
  2. QR code can be scanned from a phone, but it isn’t easy to scan a standard UPC from a phone.
  3. It has also made it possible to use your mobile smartphone comprising the QR code as an airport boarding pass or as a pass for a movie or event, and so on.
