How To Embed A Custom Logo Design In A QR Code | Content Developer. Though apparently they’ve been big in Japan for quite a while, I first learned about QR Codes only last summer after seeing them used in the campaign for the Sci Fi film District 9.
Seeing this got me to wondering – Can you customize QR Codes with your own design features, logo or brand identity? Well, it turns out you can. Pretty easily. At least up to a point. While researching the topic, one of the earliest examples I could find of someone hacking a QR Code with their own branded design elements was Duncan Robertson from the BBC. The key takeaway I got from Duncan’s pioneering work was that QR Codes have some relatively generous built in error correction, up to 30 percent in some cases. Now, what exactly does 30 percent translate into regarding how far you can push a QR Code before it breaks?
QR Code created by Takashi Murakami for SET. Interested in seeing what you can do with a customized QR Code? 1) First, you’ll want to get yourself a QR Code generator and reader. Hack. Branding a Quick Response Code (QR Code) with a custom logo (design @ IBM developerWorks) In a previous blog post , I discussed using Google Charts to quickly and efficiently create QR code images.

You can use QR codes to represent display text , open a URL, or compose an email or SMS. Quick Response codes are also known as or and can store up to 4,296 alphanumeric characters of arbitrary text. As I explored the Google Chart API for generating QR code images, I noted a particular parameter - CHLD, where you can configure the error correction level for the generated QR code.
Setting this parameter to " H" allows for data recovery up to 30% of loss rate. Given the intent of QR codes being used in the physical world, this level of redundancy is critical, to account for wear & tear on the physical QR code image. QR codes gallery. What Is A QR Code And How Does It Work? | You the Designer. Articles September 29, 2011 By now, you’re probably pretty familiar with QR codes (a.k.a. 2-D bar codes), whether or not you realize it.

The “No-Zones” QR codes are made up of black squares and white squares. The three large squares highlighted in red are the position markers. Everything Else So now that you know what you can’t edit, that means everything else is free game, right?
Now, when a smartphone or scanner reads a QR code, each byte is determined to be either completely readable or completely un-readable. The Really Cool Part In the Marc Jacobs code I linked to earlier, there was a sketch of a small girl covering part of the code. You can use the Version and Maximum Data Capacity Table on Denso-Wave’s website to determine exactly how many bytes you can turn into awesome graphic art. Ready, Set… …Go!
