QR Code breakdown…

- Come on mom, i want my own QR code...!
- You 'll have one when you get older.

Yeap, that…. thing, is a QR code and nope, i didn’t know what it does until now.

I am sure your eye has caught that thing around. Mine too. I just didn’t care enough to look it up. I saw it on magazines, posters, business cards, products packages and… today i saw it on a man’s arm. The guy had a QR code tattoo!!! He was waiting for the bus with me but i must have been staring at him too much cause he left before the bus came… I mean come oooon, i couldn’t help it!!!

I bet you can guess what happened later. When i got home, i googled it …


For Your Information


=> What is a QR Code?

It’s a type of two-dimensional barcode that can be read using smartphones. The “QR” stands for “Quick Response”, as the content of this square code is decoded at high-speed. QR Codes may appear in magazines, on signs, buses, business cards or just about any object that users might need information about. It links (stores and digitally presents) directly to text, emails, websites, phone numbers, geo coordinates, videos and images. A QR Barcode can store up to 7,089 numbers, and it is this massive amount of data that enables links to such things as videos, Facebook or Twitter pages. This act of linking from physical world objects is known as a hardlink or physical world hyperlinks.


=> Who invented the QR Code?

Denso-Wave, a subsidiary of the Toyota Group created the QR Code in 1994. Originally it was designed to be used to track parts in the vehicle manufacturing industry, but its use has since grown tremendously.


=> How do I scan a QR Code?

If you have a smartphone like an iPhone, Android or Blackberry then all you need is internet access and a reader software. There’s a number of different QR code scanner applications that can read and decode data from a QR code (e.g. http://reader.kaywa.com/). The majority of these are free and all you have to do once you install one is to use your phone’s camera to scan the QR code (vertically OR horizontally), which will then automatically load the encoded data for you. It takes literally 1 minute for someone with an iPhone or Android phone to find and install the reader (compatible to his/her phone operating system). 


=> How can I make a QR Code?

You can make your own QR Codes using barcode generators. Some QR Code generators that are currently available and free are:


And after all the philosophy, i gave it a go! 🙂

I used the kaywa generator and this is what my QR code looks like:

I know what you are thinking. “Great, now i have to download the application and get messy with my phone…”

Fair enough! BUT there is also a QR code reader for PCs! Take a look at How to Read QR Codes on Your PC, with the bctester downloaded you can read QR codes from your computer!

I have to say it doesn’t look as good as a phone bar code reader but it does the job…. (no i am not gonna tell you what my QR code says!)

So this was today’s useless information, i hope you liked it and i hope even more that you won’t go hit a QR code tattoo after reading this post… 😛

  1. You seem them all over the place in Japan. I also recall reading an article about an artist who created giant QR codes out of household goods, hair driers and such … Though I can’t find the link at the moment

  2. I finally got out from behind the eight ball and found out about those QR a few months ago, but your post is chock full of information. Now. Let’s track that guy at the bus stop down. I am DYING to know what his stood for! 🙂

  3. Great information. I was not aware of this thing until nest year. After buying new phone I came to know about this and it is a really helpful application.

  4. I had to google that one morning when I found one in an announcement while reading the newspaper. Soooo clever for commercial purposes.
    On another note, the guy with the tattoo, if he doesn’t like people looking at it, I assume he wouldn’t let anyone scan it, in which case…why would you have such a tattoo in the first place? Crazy people.

  5. I just sat here for five minutes thinking “I WANT A QR CODE TATTOO!” despite the fact that I really quite dislike tattoo’s. I LOVE cryptic stuff like that that not everyone gets! Then I realised, what if QR codes are going to become outdated and obsolete? What if they are like the mini-disks of codes, which in a short while will be replaced by something better, like – mp3’s!? That guy will be rather disappointed, having to explain to his grandchildren “Well, once upon a time, in the olden days, 2010 or something like it, marketers used codes…”

    Oh yeah – and the answer to your question … My phone 😉

    • hahaha! You really thought about it thoroughly! Sure, a QR code is intriguing, but not for tattoo! Really, what was that guy thinking??? And i totally agree with you, in a few years, codes like that are gonna be obsolete and he will have a lot of explaining to do!!! 😛

  6. You’re right my friend. I see a QR code in the mail from the post office.
    Everywhere there are signs of small QR code image. We are more advanced in technology 😛 Nice article, thank you for sharing
