The QR Code Decode – What are they and how do they work?
QR codes have slowly been gathering momentum in the business and marketing world over the last few years, but many professionals are still unsure of what they actually are and how they can be used.
What’s more, many of the intended users of QR codes are still unaware of their real value or purpose so in this post I’m going to cover some of the basics and discuss the ways businesses can use QR codes within their marketing plans.
What are QR codes?
The phrase QR code stands for “Quick Response” Code and in its most basic form a QR code is simply a barcode, in which you can encode many different forms of data which can then be read by a QR code reader.
How do they work?
QR codes are slightly different from barcodes, as although they are both a form of two-dimensional code, barcodes can only store data in a horizontal format (which is read through the spaces in between the vertical lines they are made up of), whereas QR codes can encode data both horizontally and vertically – meaning that much more data to be encoded in a smaller space.
How can you use them?
In order to view QR codes you need to download a QR code reader to your android phone (or smartphone as they are also known), and then use the scanner to take a picture of the QR code, which it will then scan and convert or direct you to whatever data has been stored in that code.
QR codes can be encoded with almost any form of data, which means that they can be scanned to show text, images, videos, maps or the entire content of a webpage.
In terms of using QR codes from a business perspective, there are numerous free QR code generators online through which you can create basic and permanent QR codes which you can then place onto any space you like, including giftware, advertising, clothing, printed products, packaging, signage, exhibition materials, as well as being placed in store windows – as they can even be scanned through glass.
You can also purchase QR code systems which can track the combined total of scans a particular code has received, as well as allowing you to produce one code that can have its data changed time and time again – meaning that you could print one code to be distributed and then update the data of this code every time you had a new offer or wanted to change the current promotion you were running, without having to generate and redistribute a new code for each.
How to download a reader to your smartphone
From a user’s point of view, there are a variety of QR code scanners that can be downloaded to most Android phones such as iPhone, Blackberry and HTC. Some newer models now have QR readers built in as standard as QR codes popularity and frequency of use increases.
iPhone
iPhone has a basic free QR code reader app by TapMedia Ltd, but you can upgrade to a HD version by DDQ for £0.69 and there are numerous other customisable versions to buy and download as well.
Blackberry
Blackberry Messenger 5.0 can read basic QR codes but if you are looking for something more sophisticated you can download either the Mobiletag scanner or the I-nigma app for free.
Mobiletag app allows you to create lists of results, track your decode history and search saved scans.
I-nigma allows you to save up to 50 decode results, which you can then share through SMS, Facebook and Twitter.
Other Android Phones
There is a whole heap of great free QR code readers available for other android phones, so here are some other suggestions:
· QR Droid – free to use and can read, scan and generate QR codes,
· Quickmark – fast scans and it reads both QR and Martix codes.
· Redlaser – free, fast and superbly accurate.
QR codes are slowly catching on, as more and more businesses and users are starting to get to grips with how to use them to their advantage, but we seem to still be a fair way from the QR code becoming a staple of the UK marketing industry.
In future posts I will be discussing the ways businesses can really benefit from using QR codes as a legitimate marketing tool – so stay tuned for that.
Happy marketing!
