What is a QR Code?

A QR code (Quick Response code) is a two-dimensional barcode that can be read by smartphones and specialized QR code scanners. It was first invented in 1994 by a subsidiary of Toyota to track vehicles during the manufacturing process. QR codes can store much more information than traditional barcodes, and can be used to store various types of data such as text, URLs, contact information, and more.

QR codes can be read by a smartphone or tablet's camera, as well as QR code scanning apps, by pointing the camera at the code. Once scanned, the data encoded in the QR code can be acted upon, such as opening a web page, adding a contact to your address book, making a phone call, or sending a message.

QR codes have several use cases, some of the most common are:

  • Marketing and advertising: QR codes can be used to provide more information about a product or service, or to direct customers to a website, a video or a landing page for a specific campaign.
  • Payment: QR codes can be used for contactless payment and mobile payments, by scanning the QR code to initiate a payment.
  • Retail: QR codes can be used in retail, to provide product information, customer reviews, and inventory status.
  • Ticketing: QR codes can be used to encode information about events or transportation tickets, which can be scanned at the gate or turnstile to gain entry or board a train or a bus.
  • Inventory management: QR codes can be used in inventory management and tracking of products, by affixing QR codes to products which can be scanned to track the product's whereabouts in the supply chain or even the delivery process.
