I noticed a small QR code in the corner of the ham package when I had breakfast. It’s on the frontside and backside, not like a normal Bar code only on the backside. Actually, I found 20% of the stuff I bought this week have QR codes. I think it’s time to write something about QR codes in higher education.

What is a QR code?

A QR Code is a matrix barcode (or two-dimensional code), abbreviated from Quick Response code. It was created by Denso Wave (a Japanese Company) in 1994. A QR Code is readable by QR scanners, mobile devices with a camera, and smart phones.

It has been increasingly used in marketing (e.g., business cards, product packaging, menus, T-shirts) because its unique, fast readability, comparatively large storage capacity, and instant various information (e.g., text, URLs, geographic coordinates). I think it’s because people like to use mobile devices so much.

Challenges of using QR codes – different voices

  • Leigh Thompson noted four Limitations of QR Codes: Character Storage, educate customers, extra devices and application, and print quality.  It’s good to know that “There are three types of characters a QR code holds: numeric, alphanumeric and binary. QR codes hold up to 7,089 numeric characters. Alphanumeric characters only fit a maximum of 4,296 characters. Binary characters hold up to 2,953 characters. The final size of the QR code does not affect the amount of characters the QR code can hold.
  • Jesse Scott pointed three challenges in his post Can QR Codes Enhance Student Learning?…: raise users’ awareness, usability of websites or online resources in mobile internet, and  required smart devices.
