What Are Dynamic QR Codes?

What Is a Dynamic QR Code?

When the information behind a printed QR code needs to change, a dynamic QR code lets you update it without replacing the code itself. Unlike a static QR code, which contains fixed content, a dynamic QR code uses an intermediary link that allows you to edit the destination and update the linked data at any time.

For example, a retail chain can use one QR code to direct customers to a promotional page, then update the offer by day, season, or store location without reprinting signage. This provides greater operational flexibility while helping reduce printing costs.

How Do Dynamic QR Codes Work?

The Technical Mechanism

When you create a dynamic QR code, the destination content—such as a website, file, or form—is not encoded directly in the QR code. Instead, the code contains an intermediary link, typically a shortened URL, stored on the QR code platform's server.

When someone scans the code:

  1. They are redirected to an intermediary address managed by the QR code platform.

  2. The system identifies the content assigned to that QR code and sends the user to the correct destination.

This intermediary setup makes it possible to change the destination without creating a new code, which is not possible with a static QR code. A dynamic QR code is therefore useful whenever the content may need to be updated after the code has been printed or shared.

What Can Businesses Gain from Dynamic QR Codes?

Dynamic QR codes offer businesses practical advantages, from content flexibility to marketing insights, especially in operations where information changes frequently.

1. Flexibility and Cost Savings

Update content without reprinting signs, stickers, or documents. This can reduce printing costs and material waste.

2. Easier Performance Measurement

With dynamic QR codes, you can:

  • Track the number of scans

  • Identify the time, location, and device used for each scan
