How to Use QR Codes for Smarter Product Packaging (5 Examples)

QR codes have moved well past novelty. Mid-2023 saw a 43.20% growth in the number of QR codes being generated globally. Countries with the highest creation rates include the US, Canada, Australia, UK, UAE, Mexico, India, and Singapore. The number of US smartphone owners using QR codes is projected to reach 99.5 million in 2025.

For product packaging, that adoption rate matters. The smart packaging market is expected to grow to $52.1 billion by 2032, and QR codes are one of its core features. A single code on a box can replace what used to require separate inserts, follow-up emails, or customer service calls.

What Is a QR Code and How Does It Work?

Quick response codes are grids of squares or pixels that smartphones can read with their camera. Originally developed in the 1990s to track components during assembly, they now redirect users to any digital destination: web pages, videos, apps, payment screens, or forms. They can be found practically anywhere — from restaurant menus to medicine bottles to product boxes.

Why do people scan QR codes? Primarily out of curiosity (39%). They also scan to redeem coupons (36%), learn more about a product (30%), and find usage instructions (28%). These motivations map directly to the most effective uses of QR codes on packaging.

Benefits of QR Codes on Product Packaging

Beyond enriching customer experiences, QR codes give brands measurable data and operational advantages:

• Marketing analytics: Each scan is a trackable data point. Scan rates, times, and locations give real insight into how customers interact with your packaging after purchase.
• Versatility: One code can link to any destination — and the destination can change without reprinting the packaging.
• Transparency: Hershey’s uses QR codes on product packaging to give customers instant access to nutrition information, ingredients, allergen details, and food disclosure statements.
• Digital integration: QR codes extend your packaging into your broader digital strategy without requiring a redesign.

5 Ways to Use QR Codes on Packaging

1. Product Identification and Authentication

For inventory management, QR codes let you track products in real time as they move through your supply chain. Each scan into your inventory system provides immediate location and status data.

For anti-counterfeiting, brands use serialized or unique QR codes to distinguish originals from fakes. Some add an embedded security image within the code — when counterfeiters copy it, the embedded security data is lost, and any smartphone can detect the discrepancy.

2. Deliver Product Information

Many brands use QR codes to give customers access to information that doesn’t fit on the label: how-to guides, tutorial videos, nutritional details, behind-the-scenes production stories, and ingredient sourcing. This is especially effective for food, beauty, and health products where transparency builds trust.

You can also use QR codes to communicate sustainability information — materials sourced, carbon offset, or recycling instructions — linking to a dedicated page rather than cluttering the packaging surface.

3. Drive Sales and Promotions

QR codes can direct customers to limited-time offers, discounts on their next purchase, or new product announcements. A subscription box that includes a QR code offering a discount on the next order creates a repeatable conversion loop without needing additional outreach.

Interactive content and augmented reality (AR) experiences can also be accessed via QR code, adding a memorable brand moment that’s shareable and difficult to replicate with standard packaging.

4. Build Customer Retention and Engagement

Coca-Cola has used QR codes to stay connected with customers throughout their journey — linking to product origin stories, loyalty programs, coupons, and product alerts. That use case illustrates the core value: a QR code turns the physical packaging into an ongoing customer relationship, not a one-time interaction.

Competitions, giveaways, and loyalty point redemption are all well-suited to QR-driven packaging experiences. The key is a clear call to action (CTA) on or near the code: “Scan to enter” or “Unlock your discount” consistently outperforms a bare QR code with no context.

5. Make Customer Support Accessible

A QR code linked to your customer support channel — “Scan to chat with us” or “Scan to send a question” — removes the friction of customers having to search for your contact details. This is especially useful for products with setup steps, usage questions, or return policies that customers may need post-purchase.

Practical Tips for QR Codes on Packaging

Personalize the Code

Customized QR codes — those with a brand color, logo, or CTA embedded — are reported to be 80% more effective than generic black-and-white codes. Something as simple as a “Scan Me” prompt or a brand-consistent color can increase scan rates meaningfully.

Print at the Right Size and Resolution

Print at high resolution so the code can be scanned at a range of distances and by different devices. Use enough negative space around the code to make it stand out from surrounding design elements. If it’s too small, it gets missed; too large, and it competes with your brand messaging.

Place Codes Strategically

Position QR codes where they’ll be seen without disrupting the primary design — inside a flap, on the back panel, or near the product information section are common placements that feel natural rather than forced.

Test Across Multiple Devices

Before final production, test your QR code with multiple smartphones and scanning apps. Confirm the destination page loads correctly and is mobile-friendly. A code that works on iOS but fails on Android, or links to a desktop-only page, undermines the experience.

Consider Legal Requirements

For food packaging, the FDA has published QR code guidelines around traceability and transparency. Follow applicable standards in your product category. Cybersecurity is also worth planning for — QR codes that collect user data should do so transparently and in compliance with applicable privacy regulations.

Pros and Cons of QR Codes on Packaging

QR codes add measurable value to product packaging when implemented with a clear purpose. The most effective uses connect customers to something genuinely useful — information they need, rewards they want, or an experience that’s worth the scan. EdgeCraft Packaging can help you incorporate QR codes into custom-printed packaging across retail boxes, mailers, cosmetic packaging, and shipping boxes.
