QR (short for 'Quick Response') Codes are two dimensional barcodes. They can be encoded with information which, when scanned by a suitable QR code reader, can be accessed. The QR codes you get with your Kimtag are encoded either with the web address of your Kimtag or a unique code which directs to your Kimtag but can be logged independently within your Kimtag stats. All your Kimtag QR codes are unique to you.
The most common device for reading QR codes is the mobile phone. A number of mobile phones now come with a QR reader already installed. For those that don't, it's fairly straightforward to download and install a suitable 'app'.
We provide EPS, JPG, SVG, PNG and PDF QR Code image formats completely free for download within your 'account settings' section and your vTag section. Click on the QR Code icons and simply download as required. If you want to just embed the QR code into your web pages, you can also use the 'cut and paste' html embed code we provide from the 'links' tab within your settings.
As a general guideline, EPS, SVG or PDF are the best files for offline printing as they are a vector lossless image format and can be scaled/enlarged without problem. We would generally advise against using JPG for offline printing.
Our Designer QR Codes are available in PNG, JPG, SVG and vector PDF QR Code file formats.
Four basic rules.
Firstly, clarity. QR Codes have error correction technology and can cope suprisingly well with distortion and even damage. However, you want as many people as possible to scan quickly and easily and that means taking care to make sure it's clear and crisp. Use the correct file format, be careful with scaling and for offline work, use good printers and paper/fabric/skin/etc.
Secondly, size. This depends a lot on your target audience and placement. There's little point printing a QR Code 1 inch / 3 cm big on a poster for example. Our advice is do a mockup, get a QR Code reader and test. Generally, avoid going smaller than 2 cm square.
Thirdly, border. QR Codes require a little white space around them. This is called the 'quiet zone' and makes a significant difference to the ability of a reader to scan effectively. Don't get too hung up on exact sizes, but aim to keep a white space certainly no smaller than half the size of the top left QR code outer square. A full 'square's worth' of space would be more than adequate.
Fourthly, contrast. QR Codes don't have to be black and white. In fact, the little squares don't even need to be square. There are some great examples in Japan of some highly modified QR Codes which scan very well. You can even purchase 'designer' QR Codes directly from Kimtag for your Kimtag with just a couple of clicks (or get them free with a Management Licence or Kimtag Plus). However, generally speaking you want the maximum number of people to scan with the minimum of fuss. That means high contrast (strong, dark colours) and avoiding pale yellow squares on a pale orange background !
We strongly recommend that you get hold of a QR Code reader and test the QR Code at every stage of an offline print process. Test that it scans quickly and correctly and links through to your Kimtag correctly. QR Codes (and our systems) are robust, but it's always better to spend a few seconds doing a test scan than have to bin a print run...
Kimtag QR codes are encoded to link directly to your Kimtag connections page so that people can choose how they want to connect with you. However, if you want your QR Code to then connect immediately through to a specific connection, then you simply need to enable 'Instant Redirect' under the AutoConnect tab in your account settings. It's very easy to do, you can change or cancel the redirect at any time and there's full instructions on the AutoConnect page on how to set things up.
Kimtag QR Codes are free to be reproduced anywhere you (legally) like. Put them on business cards, email footers, adverts, websites, t-shirts, mugs, tattoos, dvd/cd covers, promotional bags, letterheads, shop windows, badges/pins, posters, etc, etc.
QR Codes were invented by a clever Japanese company called Denso Wave. The use of QR codes is free of any license but the term 'QR Code' is a registered trademark of Denso Wave Incorporated. Where you use the phrase 'QR Code', you are required to display the phrase 'QR Code is registered trademark of DENSO WAVE INCORPORATED' somewhere near. This is not required if you only use the QR Code image itself.
