What QR Codes (2D Barcodes) Are – And Their Uses For Your Business

Have you seen one of these square garbled-looking images before? You may have seen them on a subway poster or at an airline boarding pass or on mailers. This article will give you a little background on what they are and how they can be useful to you and your company.

What is a QR Code?

QR code (abbreviation for Quick Response code) is a specific matrix barcode (or two-dimensional code) that is readable by dedicated QR barcode readers and camera telephones. The code consists of black modules arranged in a square pattern on a white background. The information encoded may be text, URL, or other data. [Wikipedia]

According to Wikipedia,

the technology has seen frequent use in Japan, The Netherlands and South Korea, while the West has been slower in the adoption of QR codes.

I got a box of KitKat last summer from Japan (thanks, Shin) that had a QR code on it. It’s slowly but surely picking up on the East Coast, as well. E.g. BJs and other companies are using them on their savings cards.

Barcodes vs. QR-Codes

Barcode

Picture of a Traditional Barcode

QR-Codes have become more popular than the typical barcode as the typical barcode can only hold about of 20 digits, whereas the QR-Code can hold up to 7,089 characters. This makes the use and diversity of QR-Codes much more appealing than their older counter part, the barcode.

Partially part of the reason QR-Codes can hold more data, is because if you compare a typical barcode to a QR-Code, you can see one major difference; barcodes only span horizontally whereas QR-Codes can span both horizontally and vertically.

Position

A great feature of QR-Codes is that you do not need to scan them from one particular angle. QR-Codes are capable of omnidirectional (360 degree’s) high-speed reading. QR-Codes scanners are capable of determining the correct way to decode the content within the QR-Code due to the three specific squares that are positioned in the corners of the symbol.

Generating QR Codes

There are a number of web sites for generating QR codes and most services they offer for free. You can also generate QR Codes with Google Charts or right in a FileMaker database, which we will demo at Devcon. The demo database uses the ScriptMaster plug-in from 360 Works and some java goodies put to use by Scott Shackelford at AEON Development Group.

Here’s a great article from Mashable on how you can make your QR codes more appealing like this. Make sure you pay attention that your code is still readable.

    Interesting article. I noticed that in the screenshot of the FileMaker database the QR code doesn’t have the 3 squares on the corners. Is that not required or just missing from the screenshot?

      Any numeric or alphanumeric characters can be stored and read form a QR code. At FileMaker Devcon we printed labels for the attendees with a QR code containing their vCard information. You can endcode a lot of information in a QR code. If you need help implementing QR code generation, we can help you.
