What are QR codes?

QR codes are square two-dimensional barcodes that can be scanned using a special scanner or – in the last few years – a smartphone. Invented in 1994, QR codes were originally used to track vehicle parts for the Japanese manufacturing industry.

Although QR codes are still heavily used in manufacturing, they become popular in the advertising industry due to their small size and huge amount of storage space, particularly in comparison to a standard barcode.

Over the last 20 years, QR codes have become one of the most popular variants of the standard barcode. They’re now used in everything from product packaging to promotional vouchers, newspapers and more.

How to scan a QR code

In the 1990s, only specialized equipment could scan and process QR codes. Over the last decade, however, almost all camera-equipped smartphones have gained built-in compatibility with QR codes, either as a standard feature or via downloadable apps.

A wide variety of QR readers are available for iOS and Android, almost all of which use the front-facing camera to scan codes. The latest version of iOS includes its own QR code reader – the Scan Code feature in the Passbook app.

If you use an Android phone, scanning QR codes is even easier. Launch the Google Search widget and select “Search with Camera.” From here, just point your camera towards your target code and your Android smartphone will automatically scan it.

How to create a QR code

Do you want to create your own QR code? QR codes can be used for a wide variety of different tasks, from memorizing a URL or email address to advertising your newest product on posters, brochures and leaflets.

Creating custom QR codes is simple. Just enter the information you want to encode into an online QR code generator and click “download” to store your code on your computer, or “embed” to place it on an advertisement or other visual design.

QR codes can store 4,296 alphanumerical characters and over 8,000 numerals. It’s generally best to limit your QR code to 300 characters of less, as many code reader apps struggle to process codes with more than 300 characters of text.

Make your business card stand out from the pack with a QR code. Instead of getting people to copy your email or phone number from your business card, let them scan it and call or email you without having to push a button.

While a QR code on your business card might seem like a gimmick, it’s a great way to get people talking about you. This innovative use of QR codes is especially useful in high-tech industries where familiarity with QR codes is very high.

Using QR codes to promote your app

Do you have a mobile app that you’d love to promote? Instead of advertising online, create an offline ad that anyone can scan. Game developers like Rovio use QR codes to promote their apps, such as in their famous Angry Birds QR code poster.

QR codes are particularly effective for promoting mobile apps, since users need to own a smartphone in order to scan them. From games to price comparison apps, a custom QR code could be just what you need to help your app’s userbase grow.
