Comments Off on QRCodes

Ivo Jansch, CEO of Egeniq and active member of the PHP community has just published an interesting article titled “QR tags beyond the hype” in which he talks about QRCodes in a non-marketing, non-technical, down-to-earth way.

Ivo breaks down the WHAT for QRCodes very nicely. If you’ve not played with them then maybe this Christmas break might be a chance for you to change that. In marketing circles they are touted as being the Internet into the Real World. (Hey, I said Ivo avoided the marketing hype, not me) Lucky for us though, Ivo just talks about what they really are and what you as a developer need to know about them.

In this post I’ll try to look beyond the hype. After the peak of inflated expectations we will eventually get to the ‘plateau of productivity’, at which point QR tags will have become mainstream. This is the moment when marketeers stop talking about it and we simply use it as part of our applications (this is a good indicator – the same happened to terms such as ajax and web 2.0). I will discuss the three major ways QR tags are applied. I hope the analysis inspires people to come up with innovative applications of QR codes.

This is a good post. It’s not technical, Ivo avoids all mention of code or implementations. It’s an easy read that does not assume much in the way of prior knowledge and even gives links to tools that help you understand some of the technical ideas he discusses like vCards and MeCards. In short, hand this article to your manager, they will be able to understand it. :)

Really, the only two things that Ivo doesn’t mention are the two tools useful in creating QRCodes.

  1. Kaywa’s QRCode Generator tool
    Very useful if you just want to crank out a QRCode to use
  2. Google’s Image API for QRCodes
    A great way to quickly add QRCode generation capabilities to an existing application.

However, since the point of the article is to get you interested, we’ll give him a pass on that.

About Cal Evans

Many moons ago, at the tender age of 14, Cal touched his first computer. (We're using the term "computer" loosely here, it was a TRS-80 Model 1) Since then his life has never been the same. He graduated from TRS-80s to Commodores and eventually to IBM PCs.   For the past 10 years, Cal has worked with PHP and MySQL on Linux OSX, and when necessary, Windows. He has built on a variety of projects ranging in size from simple web pages to multi-million dollar web applications. When not banging his head on his monitor, attempting a blood sacrifice to get a particular piece of code working, he enjoys building and managing development teams using his widely imitated but never patented management style of "management by wandering around". Cal is happily married to wife 1.33, the lovely and talented Kathy. Together they have 2 kids who were both bright enough not to pursue a career in IT. Cal blogs at http://blog.calevans.com and is the founder and host of Nomad PHP
