Imagine this: You’re at your favorite coffee shop. The barista points to a small square on the counter. You scan it with your phone. In seconds, you’ve paid, joined their loyalty program, and earned points.
What you don’t see? The coffee shop just captured your opt-in, tracked your preferences, and triggered a personalized email sequence. That very same two-inch square had now driven better results than their last billboard campaign.
QR Codes connect the real world to the online world. They’re not just shortcuts. They’re powerful tools that collect data and drive sales. In fact, 62% of businesses expect QR Codes to drive revenue growth, and 95% use them to collect first-party data.
But what exactly are QR Codes, and how do they pull this off? Let’s take a look.
What are QR Codes and how do they work?
QR Codes, or Quick Response Codes, are 2-D barcodes that store information in a pattern of black squares on a white background. Unlike traditional barcodes, QR Codes hold up to 4,296 alphanumeric characters and can be scanned from any angle.
You see them everywhere, on menus, product boxes, tickets, posters, and signs.
According to Uniqode’s State of QR Codes report, top touchpoints include:
- Mobile payment apps
- Product packaging
- Loyalty programs
- Security and authentication
- Informational use
- Advertisements
- Restaurant menus
The popularity of QR Codes in our daily lives comes as no surprise. Scanning it is simple. Your phone’s camera recognizes the QR Code pattern, decodes the embedded data, and executes the programmed action. This can be opening a website, starting a payment, or even saving contact information.
Knowing how they work is just the start. So, what are QR codes used for, and how are companies using them to their advantage?
7 surprising ways to use QR Codes in the real world
QR Codes turn every physical location into a digital entry point. Every package, storefront, event, and advertisement becomes a chance to capture data about customer behavior. Companies can finally measure the effectiveness of their offline marketing investments.
The best companies use QR Codes for more than convenience. They use them to learn about customers and improve their business. These seven ways of using QR codes show how they work.
1. Turn every purchase into data
Retailers use QR Codes to transform shopping into data collection. Target places QR Codes on shelf tags, enabling instant mobile checkout. Customers scan, pay, and skip the register entirely while the store captures purchase behavior.
Sephora prints unique QR Codes on receipts. Scanning adds purchases to digital profiles, unlocking personalized recommendations. This creates detailed customer profiles and drives repeat purchases.
Retailers can now track what customers buy, when they buy it, and how they prefer to shop. Every purchase becomes a data point for future marketing.
2. Track real-world engagement
Event organizers can use QR Codes as comprehensive tracking systems. A great example of QR code usage is Salesforce’s Dreamforce, which uses dynamic QR Codes on badges to track session attendance, booth visits, and networking connections.
Educational institutions can now also track engagement beyond attendance. MIT embeds QR Codes in course materials to measure resource use and identify struggling students early. Similarly, the University of Kansas uses QR Codes for event registrations.
3. Speed up customer service
Healthcare providers use encrypted QR Codes for patient check-in, reducing wait times while keeping patient information secure.
Hotels and restaurants optimize every touchpoint through QR Code integration. Marriott reports faster check-ins and higher revenue through QR-powered room service orders. Digital menus update prices instantly and reduce printing costs. They also use QR Codes on flyers to drive memberships.
4. Bridge offline and online worlds
Real estate agents put QR Codes on yard signs. These codes link to full property details and virtual tours, generating more qualified leads than traditional signs.
Compass, a leading real estate brokerage in the U.S., partnered with design firm Aruliden to redesign traditional real estate signs by integrating smart hardware and interactive QR Codes. Their modular “portal” sign features a round light ring, configurable printed face, and a tech module housed in a durable, weather-resistant case. The sign emits a soft glow when someone approaches, capturing attention and conserving energy. Potential buyers can simply scan a QR Code to view a virtual tour or detailed listing directly on their phone camera, allowing immediate inside-the-home exploration.
These QR Codes on outdoor advertising create measurable engagement rates where none existed before. Marketers can finally track which physical locations and materials drive the most interest.
Every billboard, poster, and sign becomes a trackable touchpoint. Physical marketing finally gets the measurement capabilities that digital marketing has always had.
5. Create interactive experiences
Brands push QR Codes beyond basic linking to create memorable experiences that engage customers while collecting valuable interaction data.
Niclas Bjuväng, former VP of Digital Technology at IKEA, shares that his team at IKEA created a simple but powerful QR Code solution during the early days of COVID-19.
This tool lets customers scan codes in-store to instantly access product information online. Despite initial internal resistance, they developed and tested the idea quickly, printing their own stickers and deploying them in stores.
The QR Codes proved to be a hit, offering a touchless, time-saving tool for both customers and staff. The result? Over 10 million scans, showing how a small idea, born from direct conversations with store teams, led to a big impact.
6. Build and enrich customer profiles
QR Codes enable businesses to connect offline behavior with digital profiles. When customers scan codes at different touchpoints, companies build comprehensive pictures of their preferences and habits.
Starbucks uses QR codes in their loyalty program so customers can scan to get rewards, discounts, and info about coffee blends. This makes it easy to engage with the brand and helps Starbucks learn about customer preferences, allowing for personalized marketing and better shopping experiences.
Loyalty programs become more sophisticated when they can track not just what customers buy, but where they discover products, how they prefer to interact, and what motivates them to take action.
7. Verify product authenticity and build trust
QR Codes can be used to verify product authenticity by linking each item to a unique digital ID that customers can scan with their phones.
Ralph Lauren has added QR Codes to the labels of its Polo clothing range to create unique digital IDs for each item.
When scanned with a mobile phone, these codes help shoppers confirm it is the original product and view product details and styling advice. This reassures customers that they’re buying a genuine Ralph Lauren piece.
At the same time, the brand uses scan data to track inventory, manage supply chains, and combat counterfeiting and gray-market sales, all done at scale across millions of garments.
To achieve results like Ralph Lauren’s, you need to choose the right QR Code type for your strategy.
Static vs. dynamic QR Codes: Which fits your strategy?
The choice between static and dynamic QR Codes determines your campaign’s flexibility and tracking abilities. Static QR Codes embed fixed data directly in the code. Dynamic QR Codes point to a URL you control, enabling real-time updates and tracking.
- When to use static QR Codes: Wi-Fi passwords, business cards, or any permanent information that won’t change.
- When to use dynamic QR Codes: Marketing campaigns, menus, event tickets, or anything you might want to update or track.
Some real-world QR code use cases are:
- Restaurant menu scenario: A pizzeria using static QR Codes must reprint table tents every time prices change. With dynamic QR Codes, they update prices instantly and track which items get viewed most.
- Event ticketing scenario: Static QR Codes work well for basic entry checks. Dynamic QR Codes do more. They track sessions, score leads, and run follow-up campaigns based on how people act at events.
- Marketing campaign scenario: A store runs holiday sales and needs to change offers each day. Dynamic QR Codes let them swap deals and track results. Static QR Codes would mean making new ads for every offer.

Is your business ready to scale up with QR Codes?
Here is a decision checklist to evaluate your QR Code readiness across seven critical areas:
✅ Campaign goal clarity: Set specific, measurable outcomes.
Example: A retail store wants to use QR Codes on in-store posters. A clear goal would be: “Drive 500 product page visits and 50 coupon redemptions via QR Codes in 30 days.”
✅ Tracking infrastructure: Set up analytics before launch to capture performance data. Or go for the QR Code service provider that provides analytical insights such as scan locations, devices used, etc.
Example: A university prints QR Codes on open house flyers. Each QR Code links to a trackable URL with UTM parameters to monitor RSVPs and page views via Google Analytics.
✅ Compliance framework: Ensure you follow data privacy laws and document how data is handled.
Example: A food delivery app uses QR Codes on receipts to collect customer feedback. They update their privacy policy to disclose how reviews are collected and used under GDPR.
✅ User experience design: Design the full journey, from the moment someone scans to the final action you want them to take.
Example: An event organizer places QR Codes at the venue entrance that lead directly to a mobile ticket check-in page, followed by a session schedule tailored to the attendee’s registration.
✅ Brand customization: Your QR Codes must reflect your brand visually to build trust and recognition.
Example: A local coffee shop uses QR Codes on table tents. The codes are designed with the shop’s logo, colors, and a call to action such as “Scan to Order Without Waiting in Line.”
✅ Analytics utilization: Assign someone to regularly review performance and act on the data.
Example: A non-profit runs a QR Code-based donation campaign. The fundraising team monitors scan rates weekly and sees more traffic during email pushes, prompting them to double down on those efforts.
✅ Technical support: Ensure someone can quickly fix issues such as codes not scanning or landing pages breaking.
Example: A real estate agency uses QR Codes on property signs. The marketing team tests each code monthly and keeps a checklist to ensure every code links to the latest property listing.

Making every real-world touchpoint measurable
QR Codes evolved from inventory tracking tools to sophisticated attribution systems. They’re the missing link between offline experiences and digital measurement.
Smart businesses don’t ask, “Should we use QR Codes?” They ask, “How can QR Codes make our offline investments measurable?”
Every physical touchpoint, from packaging to billboards, becomes a data collection opportunity. Every scan tells you who engaged, where they were, and what happened next.
The brands winning with QR Codes treat them as strategic assets, not tactical add-ons. They customize for brand consistency, track for continuous improvement, and optimize based on real behavior.
Your customers already know how to scan. The question is: Are you ready to measure what happens next?
FAQs
QR Codes eliminate friction in five common scenarios: restaurant ordering (no waiting for menus), event check-in (skip registration lines), payment processing (no card swiping), Wi-Fi access (instant connection), and information retrieval (immediate product details). The average QR Code interaction takes 3 seconds versus 45 seconds for traditional alternatives.
QR Codes themselves are safe, but scan destinations require caution. Verify the URL preview before proceeding, look for HTTPS connections, and avoid entering sensitive data through QR-accessed forms. Legitimate businesses use branded QR Codes with clear messaging about the scan destination. Report suspicious QR Codes to venue management immediately.
Static QR Codes embed fixed information directly in the code pattern; once created, the destination never changes. Dynamic QR Codes point to a URL you control, allowing destination updates, scan tracking, and A/B testing. Static codes work for permanent information like Wi-Fi passwords. Dynamic codes enable campaign optimization and compliance management.
Dynamic QR Codes capture seven data points: total scans, unique users, geographic location, device type, scan time, referral source, and post-scan actions. This data enables heat mapping, audience profiling, and ROI calculation. Privacy-compliant platforms anonymize personal information while providing aggregate insights for optimization.
QR Codes scan successfully on most materials with enough contrast. Proven surfaces include paper (98% success), plastic (95%), metal (91%), fabric (87%), and glass (84%). Avoid reflective surfaces, extreme curves, and low-contrast combinations. Test scanning at various distances and lighting conditions before mass production. Maintain a 4:1 contrast ratio for optimal performance.
