QR Codes

What is a QR Code?

A QR (or ‘quick response’) code is a matrix-shaped, computer-generated barcode, containing text information. It’s commonly used to deliver vCards, website URLs, emails, telephone numbers or even templates of text messages. The code can be scanned by a camera phone or webcam, and the information retrieved quickly and easily.

Reading a QR Code

In order to read a QR code, you’ll need a camera phone or a computer with a webcam, and some specialised software. There are lots of code-readers around, but they all work in essentially the same way: launch the reader, point the camera at the QR code, and watch what happens next.

How do I get one on my Business Cards?

We’ve built an easy tool that will allow you to create a QR code and add it to your business cards. Just start to make cards and you'll see the option. You’ll be able to make a QR Code that dials a phone number, directs to a web address, or adds a v-card when scanned. Just enter your information, and we’ll create a code and add it to your business cards.

Can I get it on the image side?

Yes.

Can I get it in different colours?

QR Codes rely on the contrast between the black and white sections when being scanned. While it’s technically possible to have a different background colour on the code, it reduces the chance that a phone or webcam will be able to read it. Therefore, the MOO codes will always be black and white. You can still change the background colour on your cards, but the QR code background will remain white.

Why is there a white box around the code?

This is called a “Quiet Zone” and it helps a QR scanner differentiate between what is part of the code and what is not. Without this white space, it’d be impossible for your code to be read.

I want a logo as well as a QR code

At the moment our Business Card templates do not allow more than one image on the Details side of the card. However, keep your eyes peeled for future developments, as we hope to develop that ability in the future.

What is a vCard?

vCard is a file format standard for electronic business cards. vCards can be attached to emails, to websites or hidden in QR codes. They can contain name and address information, phone numbers, e-mail addresses, URLs, logos, photographs, and audio clips.

Other products?

Currently our QR Code tool only works for Business Cards. However, we hope to roll it out to other products soon. Keep your eyes and ears on the site for developments!

My phone won’t scan the code on my card

Different QR Code readers will have different success rates. Most phones with a QR Code reader will be able to easily scan simple QR codes with phone numbers or web URLs embedded in them. However, for QR Codes containing a vCard, we’d recommend a phone camera with at least 5 megapixel resolution, due to the density of information contained in the code. Basically, the more information you add to the code, the harder it’ll be for the code reader to read it.

We’ve tested our QR codes on all the major phone platforms, and with most of the leading phone models to ensure compatibility. However, older phone models (iPhone 3GS and below, older Blackberry models) may struggle to successfully scan a complex QR Code due to their low resolution cameras.

Can I change what my QR Code does after I’ve printed my cards?

No, your QR code is fixed once you’ve printed your cards. However, look out for closer integration of QR codes into your MOO account in the future!
