Quick Response Code

  • QR code stands for Quick Response Code. It's the trademark or a kind of 2D bar code that contains a matrix of dots.
  • It had been first designed or invented in Japan in 1994 by a Japanese automotive company Denso Wave to track vehicles during manufacturing.
  • Later it became popular outside the automotive industry due to its fast readability and better storage capacity as compared to standard UPC barcodes.
  • A QR code comprises black squares with white a background arranged during a square grid.
  • It is often read both horizontally and vertically by an imaging device like a camera, Smartphone with a built-in camera, QR scanner, etc.
  • We will say that it's a machine-readable optical label that contains the information about the item, object, or product to which it's attached.
  • After scanning, the imaging device converts the dots within the code into numbers or a string of characters. For example, scanning a QR code using your mobile may open a URL in your phone's browser.
  • All QR codes are within the kind of a square shape, which defines the orientation of the code and thus makes each code unique in itself. No two QR codes can have similar pattern.
  • The QR code has two major advantages over traditional UPCs; first, the QR codes are two-dimensional as they contain significantly more data than a one-dimensional UPC.
  • Second is that it are often scanned from a screen, but a standard UPC can't be scanned from a screen.
  • Furthermore, it made it possible to use your Smartphone containing QR code as a boarding pass at the airport or as a pass or ticket for an occasion, movie, etc.

History of QR Code

  • The QR code system was invented by the Japanese company Denso Wave in 1994.
  • Its purpose is to trace vehicles during manufacture; it's designed to permit high speed component scanning.
  • QR codes are now being used during a much wider context, including commercial tracking applications and feature-based applications targeting mobile users (called mobile tagging).
  • QR codes is used to display text to a user, add a vcard contact to a user device, open a uniform Resource Identifier (URI), connect with a wireless network, or write an email or text message.
  • Most QR code generators are available as software or online tools. QR code has become one among the most commonly used types of two-dimensional codes.


  • URLs have also helped with marketing conversion rates within the pre-Smartphone era, but have faced many limitations over the years: ad viewers usually need to type URLs and that they do not have an internet browser ahead of them once they first use ads.
  • They forget to go to the site later, don't bother typing the URL, or forget to type the URL.
  • Semantic URLs reduce these risks, but don't eliminate them. With the arrival of smart phones the lack to access the web site immediately is not any less of a problem, although the problem of typing during a URL still persists and redirects the use of QR code to form the URL for immediate use.
  • Most QR code generators offer a dynamic QR codes.
  • Dynamic QR codes are repeatedly modified because they use the placeholder URL, which makes scanning easier and faster than their counterparts - static QR codes
