Initially used for tracking parts by Toyota, these next generation bar codes are appearing everywhere from supermarkets to concert posters.
A QR (Quick Response) code is a two dimensional code (matrix) that is readable by devices such as a dedicated QR reader device or Smartphones. Being a two dimensional matrix (horizontal and vertical) allows more data to be encode than a traditional barcode, where data is only encoded horizontally.
This increase in data representation, not only in size but also the ability to hold numbers and characters, allows for quicker data input where otherwise the same data would have been manually typed in.
Examples of usage range from business cards, parcel shipping labels, airline boarding passes to ‘like’ something on Facebook.
More over when scanned using a device such as a Smartphone, instructions can be embedded within the QR code to direct the phones web browser to launch to a specific website where more information can be found.
In today’s world where digital content can be accessed instantaneously via Smartphones, QR Codes allow convenience for both businesses and consumers to send and receive information quickly and accurately.
