What Are QR Codes and NFC, and How to Use Them in an Omnichannel Strategy?

When people talk about omnichannel strategy, they think about consistency of communication across channels - enabling a customer to start a purchase on their phone and complete it in-store, or ensuring that an email references what they saw in a social media ad. That matters, but there's one piece of the puzzle that tends to be underestimated: the moment when a customer physically encounters a brand in offline space. A brick-and-mortar store, an event, a package, a poster - these are touchpoints with enormous potential for building relationships and collecting data. QR codes and NFC technology are precisely the tools that transform these moments into something lasting and measurable.

‍

What Is a QR Code and What Does It Actually Do?

A QR (Quick Response) code is a two-dimensional barcode that, when scanned with a smartphone camera, directs the user anywhere online - a webpage, a form, a landing page, a video, or an app. Unlike a traditional barcode, which stores a single line of data, a QR code encodes information across two dimensions, allowing it to carry significantly more data - and it reads from any angle, without specialized scanners.

For the user, it's one of the simplest gestures a smartphone allows. Open the camera, point at the code, tap the notification - and within a second, they're exactly where the brand wants them to be. No typing, no searching, no memorizing a URL. QR codes eliminate all of that friction.

This simplicity is precisely what makes QR codes a particularly effective lead generation tool - collecting contact information from prospective customers. When a customer scans a code placed on an in-store sticker, product packaging, or a poster, they can reach a sign-up form within seconds and leave their phone number or email address. No friction, no need to search for the brand's website, no unnecessary intermediate steps. In environments where the interaction window with a customer is short - a checkout counter, the moment of receiving a package, a trade show booth - that speed is critical.

But what makes QR codes a truly powerful tool in an omnichannel strategy isn't simply the redirect to a link. It's the fact that each code can carry a unique identifier - assigned to a specific medium, location, or campaign. This means that when a brand reviews its scan data, it knows not just "how many times someone visited the page," but also: which poster generated that visit, from which city, from which in-store sticker, from which OOH material. A QR code on a flyer and a QR code at the checkout can point to the same page - but the system records them separately and delivers data on which medium is actually driving engagement.

This fundamentally changes how offline campaigns are planned and evaluated.

‍

Where Does a QR Code Physically Appear?

The versatility of a QR code lies in the fact that it works on any flat surface. A sticker at the checkout, a poster in a shop window, an insert in a shipping box, trade show materials, a billboard, a flyer, a catalog, product packaging - anywhere a graphic can be printed, a QR code can be placed. There are no format or environmental constraints.

This means QR naturally fits into every stage of the customer's journey with a brand - in-store, post-purchase, at the moment of delivery, in public spaces, or at events. On each of these surfaces, a QR code can direct customers to a sign-up form, a product offer page, or a loyalty program - transforming a passive brand touchpoint into an active lead-generation channel.

What Is NFC and Why Should It Be Thought of Differently Than QR?

NFC (Near Field Communication) is a short-range wireless communication technology. In practice, it means that devices can exchange data simply through proximity - no scanning, no opening the camera, no additional steps. The user simply holds their phone near an NFC tag and the device responds automatically: opening a webpage, a form, an app - whatever has been assigned to that tag.

NFC is not a new technology - it has long powered contactless payments, which have become standard practice. Anyone who has ever paid with a card or smartphone without inserting it into a terminal has used NFC. This context is important: users don't need to learn this technology. The tap gesture is already familiar and intuitive to them.

In marketing and sales, NFC most commonly takes the form of a sticker or tag placed in a physical space. A single user gesture replaces an entire sequence: reaching for the phone, opening the camera, framing the code, waiting for it to read. NFC eliminates every one of those steps.

From a lead generation perspective, this is a fundamental shift. The fewer steps that stand between a customer and a sign-up form, the higher the conversion rate. NFC reduces that distance to an absolute minimum - the user lands on a landing page in a fraction of a second from the moment they decided to engage. In high-traffic environments with a limited interaction window, that seamlessness directly translates into the number of contacts captured.

From a technical standpoint, NFC operates natively on the vast majority of modern smartphones - both Android and iOS - without requiring any app installation. The range of a few centimeters, which might seem like a limitation, is in practice an advantage: the interaction is precise and intentional. A user who holds their phone up to a sticker does so deliberately.

NFC in Physical Retail Environments

NFC is a particularly powerful tool in environments where traffic is high and the interaction window is short. A brick-and-mortar store, a gym, a hotel reception, a trade show booth, a restaurant - anywhere a customer is physically present for a moment and has their phone within reach, NFC can trigger an action in a way that feels natural and unobtrusive to them.

An NFC tag at the checkout counter, at the entrance, or next to a specific product on the shelf - each of these locations is a point where a customer and brand can establish lasting contact. The customer holds their phone near the tag, lands on a sign-up form, leaves their number - and from that moment on, the brand has the ability to communicate with them directly, regardless of whether they ever return to that same store. And just as with QR codes - each tag carries a unique identifier that enables activity measurement down to the location level.

‍

QR and NFC - Two Technologies, One Strategy

QR codes and NFC accomplish the same objective: moving a user from physical space to digital. But they do so in different contexts and in different ways - and that's precisely why they're most powerful together, as two complementary paths within a single strategy.

QR works everywhere a medium is flat and printed - on a poster, packaging, a flyer, a billboard, a package insert. It can reach a customer through virtually any communication format, whether it's a brick-and-mortar store, an OOH campaign, event materials, or e-commerce fulfillment. There is no environment where QR cannot be deployed.

NFC, on the other hand, is a technology that excels in high-traffic physical environments - where speed matters and minimizing every point of friction in the user experience is paramount. A single tap of the phone is the simplest possible gesture one can ask of someone.

2way stickers combine both technologies in a single physical object. The user can engage through whichever interaction they find most natural - scanning the QR code or tapping with their phone - and the system logs every action with an assigned location identifier. The brand doesn't have to choose between technologies or wonder which customer segment each will serve better. Both are served simultaneously.

‍

How Do QR and NFC Fit Into an Omnichannel Strategy?

Omnichannel in practice is a brand's ability to continue a relationship with a customer regardless of which channel that first contact occurred in. This requires two things: identifying the customer (i.e., capturing their contact information) and having measurability across every touchpoint. QR and NFC address both needs simultaneously - and they do so in places where traditional lead capture methods have limited reach: in the physical environment where the customer is present but not sitting in front of a computer screen.

Retail and Brick-and-Mortar Stores

A physical store offers something no digital channel can replicate: direct, hands-on contact between the customer and the product and brand. A customer who walks into a store is already engaged. They're there for a reason.

QR and NFC stickers placed at key points in the space - at the checkout, at the entrance, in fitting rooms, next to selected products - allow that physical presence to be converted into a lasting digital relationship. A customer who scans a code or taps their phone can join a loyalty program, sign up for promotional notifications, or receive a discount code for their next purchase. The entire process takes a matter of seconds and requires nothing from the customer beyond the phone they already have in their pocket.

What distinguishes this approach is a level of measurability that was difficult to achieve in traditional retail. Each sticker carries a unique identifier, so the brand can see precisely which location in the store generates the most engagement. Knowing that the sticker at the checkout delivers three times more sign-ups than the one at the entrance is a concrete signal for optimization - both of material placement and of the store layout itself. In the best-performing locations, a single sticker point generates an average of approximately 30 new contacts per day.

E-Commerce and the Post-Purchase Moment

E-commerce has a natural advantage when it comes to data: the brand knows who visited the site, what they browsed, what they added to the cart, where they dropped off. But there is one moment that frequently escapes this digital tracking - the physical receipt of a package.

A customer opening their order is at the peak of their positive sentiment toward the brand. They just received what they wanted. It's the ideal moment to offer them something more - a discount on their next order, access to exclusive offers, an invitation to a loyalty program. A QR code on a package insert or shipping label takes the customer directly to a sign-up form and converts a one-time buyer into a subscriber the brand can communicate with directly going forward.

This closes the loop: the customer purchased online, received physically, and re-entered the digital channel through a physical touchpoint.

Restaurants and Dietary Catering

In the food and beverage industry, the frequency of customer contact has a direct impact on revenue. A customer who visits once and leaves without any trace in the brand's system is a customer who is difficult to reach again. An NFC sticker at the counter or on the table gives them a natural opportunity to stay connected - without searching for the brand on social media.

For dietary catering providers, where customers regularly pause and resume subscriptions, the ability to reach them directly at the right moment is critical. A customer who has taken a break and isn't returning often simply needs the right nudge - a message with a specific offer, sent at the moment they're ready for it. Data collected through QR and NFC, combined with behavioral insights, enables those moments to be identified with precision.

Fitness and Wellness

Fitness facilities operate in spaces where customers are present regularly and repeatedly. Gyms, yoga studios, sports clubs - every visit is a brand interaction, and also a potential opportunity to build a relationship with a new user.

Stickers at the entrance, at reception, next to equipment, or in changing rooms enable both contact capture from new visitors and engagement of existing members in loyalty programs, referral incentives, or exclusive offers. The unique identifiers on each sticker reveal which areas of the facility attract the most interest - information that's valuable not only from a marketing perspective, but also for space management.

Events

An event is, by definition, a one-time environment - a customer appears once, in a specific place and time. Without tools for capturing contacts, that moment passes and leaves no trace in the brand's systems.

QR and NFC stickers on stands, at entrances, on conference materials, and throughout event and trade show spaces convert a one-off interaction into the starting point of a long-term relationship. An attendee who scans a code or taps their phone can join a mailing list, download event materials, be notified about future editions, or receive exclusive offers. QR codes in OOH format - on digital billboards and posters in the public space surrounding an event - allow outdoor advertising effectiveness to be measured with accuracy comparable to digital campaign analytics.

‍

Why Measurability Changes the Approach to Offline Marketing

QR and NFC introduce into the physical world a level of analytics that was previously reserved for digital channels. Every scan, every phone tap, every sign-up is a data point - data about which location generated the contact, at what time activity peaks, which materials are actually driving conversions. The unique identifier assigned to every QR code or NFC tag means a brand no longer operates at the level of "the campaign generated X sessions," but at the level of "this specific sticker at the checkout in the store on Main Street generated 47 new contacts this week."

This is a qualitative shift in how budgets are planned and activities are optimized. Instead of distributing materials evenly and hoping something works - the brand has data to make fact-based decisions.

In the 2way platform, every interaction is logged in real time and accessible in an analytics dashboard. Data can be exported to Excel or synchronized directly with the brand's CRM, so analytics from offline channels flow into the same repositories as data from digital campaigns. The brand sees the full picture.

The Quality of the Contact Database

There is one aspect of omnichannel strategy worth stating plainly: the raw number of contacts collected is not a measure of success. A database composed of random, unverified numbers or email addresses generates cost and delivers disproportionate results. What matters is quality - contacts of real, active users who have consciously chosen to stay in touch with the brand.

The double opt-in mechanism built into 2way ensures precisely that quality. A user who scans a QR code or taps an NFC sticker and lands on a sign-up form enters their phone number - and then confirms it via a one-time verification code sent by SMS. Only after that confirmation does the number enter the database. No one can sign someone else up without their knowledge, no false contacts reach the database, and every person in the database has given consent actively and consciously. Data shows that approximately 95% of users who enter their number go on to confirm it with the code - meaning the database is composed almost entirely of real, engaged contacts.

A high-quality database translates into higher open rates, higher CTR in SMS campaigns, and a direct impact on sales conversion.

‍

SMS as the Natural Next Step

QR and NFC capture the contact. But the contact is only the beginning of the relationship. What a brand does with the database it builds determines whether the investment in list-building delivers a real return.

SMS is a channel that stands out above all others in terms of effectiveness. 95% of SMS messages are read within the first three minutes of delivery. CTR in SMS is 6–8 times higher than in email. SMS doesn't land in a spam folder - it appears directly on the phone screen, in the space the user checks dozens of times a day.

For a brand that has built a database through QR and NFC, SMS is the tool for conducting that communication in a direct and effective way: informing recipients of new promotions, reactivating customers who have stopped purchasing, recovering abandoned carts, and delivering personalized offers based on purchase history.

Individual discount codes, which 2way assigns to every user in the database, allow the effectiveness of each campaign to be measured at the level of a single person. The brand can see who used a code, when, and what revenue it generated. It can also see who didn't use it - and can send an automated follow-up at the right moment. The system surfaces campaign ROI: how much a campaign earned relative to what it cost.

From the First Scan to a Loyal Customer

An omnichannel strategy built on QR and NFC is a system that operates on multiple levels simultaneously. At the contact acquisition layer - it converts every physical brand touchpoint into an opportunity to join the database. At the analytics layer - it delivers data on which locations, materials, and campaigns perform best. At the communication layer - it enables brands to reach customers with precise, personalized messages at the moments when those messages are most likely to drive action.

The 2way platform unifies all of these elements in a single tool: database building through QR and NFC stickers, contact verification through double opt-in, real-time analytics, SMS automations triggered by customer behavior, and CRM integration. Implementation takes an average of one day, and a dedicated account manager guides clients through the entire configuration and helps launch the first campaigns.
