In a context where consumers are increasingly impatient and interactions happen within seconds, QR codes have emerged as an extremely effective and flexible marketing tool. From printing on packaging, flyers to embedding in emails, social media, or promotional videos, QR codes help brands shorten the customer journey, enabling viewers to take immediate action—scan the code to receive offers, register, view more information, or make a purchase.

With almost zero cost and easy measurability, QR codes are gradually becoming an indispensable part of marketing campaigns.

What is QR code in marketing?

QR code (Quick Response Code) is a type of 2D barcode that can contain links, text, videos, attachments, etc. Users simply scan the code with their phone to quickly access the content designed by the marketer.

What does QR code bring to marketing?

• Diverse customization: Can be personalized for each customer segment

• Omnichannel connection: Supports both offline and online

• Cost optimization: Easy to create, inexpensive

Applications of QR code in traditional marketing

Although technology is developing rapidly, traditional marketing remains an important channel for building brand awareness and reaching customers at points of sale, events, or local areas. You can fully leverage QR codes for:

1. Printing QR codes on product packaging

Each product package can have a QR code so customers can access usage instructions or watch real experience videos from other customers. To stimulate demand, you can also create after-sales programs attached to this detailed information via barcodes on the packaging. Once consumers have purchased the product, they will scan the barcode to get a promotional code for their next order.

Example: A coffee package with a QR code leading to a video introducing the coffee farm and the proper brewing method.

2. QR codes on printed materials: posters, brochures, catalogues

• Access promotional landing pages

• Book a consultation or product demo

• View the full product portfolio without printing hundreds of pages

👉 Tip: Print the QR code at the bottom right corner for easiest scanning.

3. QR codes at events and trade fairs

• Quick check-in
• Collect customer information
• Download documents, vouchers, gift codes

👉 Small tip: Use standees or LED screens to display large QR codes, easy to scan from a distance.

4. Business cards and digital business cards

Instead of just listing your phone number, add a QR code that leads to your personal information: personal profile (LinkedIn, Portfolio), company website, or access to product introduction documents, etc. You can be creative in designing the information for your barcode link.
