What is QR Code?

QR is an abbreviation for Quick Response, and is used very commonly (at least in Singapore) in many publicity media, primarily for the convenience of linking to physical and online content. It looks like a dot-matrix box like design (see below) :-


History of QR Codes

QR Codes were originally invented in 1994 by Denso Wave, a Japanese company that is a subsidiary of Toyota Motor Corporation in their quest to track car parts during the automotive assembly process (“QR Code”, 2013). They are 2 dimensional barcodes that provide substantially more flexibility than standard barcodes. Standard barcodes can only contain 20 alpha-numeric characters (Struyk, 2012). QR Codes can contain 7,089 numeric or 4,296 alphanumeric characters, including non-alphabet characters, such as Japanese and Chinese characters (Gazin, 2011) . This provides much greater flexibility. QR codes can also be linked to websites, e-text, online images, videos, audio files, sign-up forms, telephone numbers–the possibilities are endless!

Here’s a great video introduction to QR Codes:

Thinking Points

  • Are QR Codes just the latest fad?
  • Do you have any stories of trying out QR codes in your library that either have or haven’t worked?
  • Are QR codes too difficult to scan? What problems have you experienced?
  • How could libraries get more creative with QR codes?
  • What do you think of the ‘QR codes replacing a public library’ concept in Klagenfurt, Austria?
  • QR Code links are just as susceptible to broken links as stand weblinks. Is this a problem?
