What Is a QR Code? How Businesses Use QR Codes for Marketing

Last updated: 10 September 2026

A QR code is a scannable code that allows people to open digital information using their smartphone camera.

Instead of asking someone to type a long web address, search for your business or manually save a phone number, a QR code can take them directly to the next step.

That destination could be a website, WhatsApp chat, promotion, menu, bio link, location, registration page or other digital resource.

For businesses, QR codes are particularly powerful because they connect offline attention with online action.

How Does a QR Code Work?

The process is simple.

There is usually no need for the customer to manually type a URL.

That reduction in friction is what makes QR codes useful for marketing.

Why Do Businesses Use QR Codes?

QR codes make it easier to move a customer from something physical to something digital.

Businesses can use them to:

• Open a website
• Start a WhatsApp conversation
• Display a digital menu
• Show a promotion
• Collect registrations
• Share contact information
• Open a bio link
• Send customers to a location or map
• Collect reviews
• Share event information
• Provide product information
• Connect printed advertising to online campaigns

QR Codes Connect Offline Marketing to Online Action

This is one of the most useful ways to think about QR-code marketing.

A physical marketing asset normally cannot be clicked.

A QR code gives that physical asset a digital next step.

Where Can Businesses Use QR Codes?

1. Posters

A QR code can turn a poster into an interactive marketing tool.

Instead of only displaying information, the poster can direct people to a promotion, order form, WhatsApp chat or landing page.

2. Restaurant Tables

Restaurants can use QR codes for digital menus, ordering, promotions, loyalty campaigns or customer reviews.

3. Exhibition Booths

A booth visitor can scan a QR code instead of manually entering a website or filling in a long paper form.

The code could lead to a product catalogue, lead form, WhatsApp conversation or promotional page.

4. Business Cards

A QR code can turn a traditional business card into a gateway to your website, contact page, digital vCard or bio link.

5. Flyers and Brochures

Printed material has limited space. A QR code lets you move detailed information online while keeping the printed design clean.

6. Product Packaging

Businesses can direct customers to product information, instructions, warranty registration, promotions or support.

7. Events

QR codes can be used for registration, check-in, event schedules, maps, speaker information or feedback.

8. Shop Counters

A small QR stand at the counter can promote WhatsApp, loyalty programmes, reviews, communities or future promotions.

How Can You Use a QR Code for WhatsApp?

One practical use is to connect a QR code directly to a WhatsApp conversation.

Instead of displaying a phone number and asking customers to save it manually, the flow can be:

This is useful for enquiries, reservations, sales, customer service and lead generation.

Should a QR Code Point to a Bio Link?

Sometimes, yes.

If customers may need several different actions, sending them to a bio-link page can provide more flexibility than sending everyone to one fixed destination.

Why Combine a QR Code With a Short URL?

QR codes and short URLs work very well together.

Imagine this printed on a poster:

Customers now have two ways to respond:

• Scan the QR code
• Type the short URL manually

This improves accessibility and makes the marketing asset more useful.

Static vs Dynamic QR Codes

You may come across the terms static QR code and dynamic QR code.

For long-running marketing materials, being able to manage the destination behind a link can be extremely useful.

Can You Track QR Code Campaigns?

Yes — particularly when the QR code points to a trackable short URL or managed digital destination.

This can help answer questions such as:

• How many people interacted with the campaign?
• Which poster generated more traffic?
• Which booth or location performed best?
• What devices did visitors use?
• Which campaign source generated clicks?

Instead of treating offline advertising as something impossible to measure, QR codes can help create a trackable bridge between physical marketing and digital analytics.

Use Different QR Codes for Different Marketing Locations

One common mistake is using exactly the same campaign link everywhere.

Imagine a business promotes the same offer through:

• Store counter
• Flyer
• Exhibition booth
• Restaurant table
• Outdoor poster

If every QR code uses exactly the same tracking setup, it can become harder to understand which placement performs best.

Instead, create separate trackable links or campaign variations for each placement.

Now your offline campaign becomes easier to compare.

What Makes a Good Marketing QR Code?

1. Make It Large Enough to Scan

A QR code that is too small may be difficult to scan, particularly when printed on posters or displayed from a distance.

2. Maintain Strong Contrast

The QR pattern should be easy for a smartphone camera to distinguish from the background.

3. Do Not Overcomplicate the Design

Custom colours, logos and frames can improve branding, but readability should always come first.

4. Tell People Why They Should Scan

A QR code by itself does not explain the benefit.

Instead of simply printing:

SCAN ME

try:

• Scan to View Menu
• Scan to WhatsApp Us
• Scan to Claim This Offer
• Scan to Register
• Scan to Join Our Community

5. Test Before Printing

Always test your QR code using different phones before printing hundreds or thousands of copies.
