QR Codes Overview

A guide to best practices and implementation.


From Wikipedia, the free encyclopedia

A QR code (abbreviated from Quick Response code ) is a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of industry due to its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of any kind of data (e.g., binary, alphanumeric, or Kanji symbols) [1] .

  Created by Toyota subsidiary Denso Wave in 1994, the QR code is one of the most popular types of two-dimensional barcodes. It was designed to allow its contents to be decoded at high speed. [2]

The technology has seen frequent use in Japan and South Korea ; the United Kingdom is the seventh-largest national consumer of QR codes. [3]


















QR Codes require end user participation. You must keep in mind the devices and their limitations.

System Requirements (Canada)

In Canada, smart phones and tablets are not sold with pre-installed scanning software. The end user must download and install the software which was designed for his or her device. The most popular brands of phones are Iphone, BlackBerry and Android. Each of these brands have app stores in which the end user can install free scanning software.

Limitations on Devices

It is important to remember that not all devices are equal. Some devices may react differently to scanning a QR code than others. For instance, Android can scan the WIFI connector QR code but Apple devices can not.

Marketing Tips


QR Think

Here are a few tips to help you or your business launch a successful marketing campaign.


  • If you are linking to a URL, make sure the content is mobile friendly. The end users device will likely have limited memory, limited power, limited viewing area and a slow Internet connection. Trying to load a full web page on a mobile device consumes far too much bandwidth. Mobile optimized sites deliver the best end user experience.


  • Keep your URL short. If you need to create a QR code for a long URL, use a link shortening service such as http://bit.ly or http://goo.gl.


  • Do not alter the QR code or adjust the size. Doing this will make it difficult for scanning software to detect the QR code which could result in a bad impression for your end user.

  • Remember who is scanning your code. Most likely, the end user scanning your code is doing so with a mobile device. They are probably looking for specific information about your company such as the address, phone number, or contact page.

SaaSDev Inc. recommends that you speak with an expert regarding QR codes before launching any advertising campaigns in which they are used.
