Quick Response (QR) Code

What is a quick response (QR) code?

A quick response codes (QR code) is a scannable barcode that directs users to a specific website via a unique URL. It is a type of high-density, two-dimensional (2D) barcode that stores information in a square-like structure and can be scanned easily by digital devices.

QR codes are everywhere, from menus to social media to TV ads, and their popularity has grown significantly due to their contactless nature and consumer acceptance.

One of the advantages of QR codes for digital and mobile marketing is their flexibility. They can be used in the physical world or online, and they have a much broader reach as a result. QR codes are increasingly used to create engaging, branded, and personalized campaigns across all channels.

Types of QR codes

Static QR Code

A static QR code has an embedded URL as part of the code pattern, which means that once it’s created, editing it is no longer possible. Static QR codes are useful in situations where updates are not necessary, such as during singular marketing campaigns or seasonal promotions.

Dynamic QR Code

A dynamic QR code has a short URL embedded in the code, which redirects users to the destination website URL. The destination URL can be changed after the QR code has been created, while the short URL embedded in the code remains the same. Each time a dynamic QR code is scanned, it captures channel data. This allows developers to monitor performance by channel and make any necessary adjustments during the course of a campaign.

Mobile App QR Code

Many mobile apps use QR codes to track app installs from offline campaigns. Using a mobile linking platform (MLP) to track, create, and manage QR codes gives the ability to link to app content directly instead of just the app. It also enables updates to the links and content behind the QR codes, so you don’t need to update your printed materials with a new QR code.
