Retail today runs on context: actual, in-the-moment understanding of where a shopper is, what they’re doing, and what they might need next. And few innovations deliver that level of precision like beacon technology.
Proximity marketing allows businesses to target potential customers based on how physically close they are to a specific location. As proximity marketing gains momentum, the global beacon market is exploding, from $22.7 billion in 2025 to a projected $718.6 billion by 2033.
You can’t see it, but it’s everywhere: Starbucks is experimenting with mobile/location triggers; luxury hotels across North America and Europe are using beacons for keyless entry, concierge prompts, and frictionless check-ins; and modern retailers are layering beacons into aisle-level navigation, dwell-time analysis, product discovery, and VIP clienteling.
Ahead, you’ll learn how beacon technology works today, why it’s powering the next wave of proximity marketing, and how to get started.
Beacon technology is a smart retail tactic where tiny, low-energy Bluetooth devices (BLE beacons) are placed throughout a store to detect when a shopper’s smartphone is nearby. When someone with your app (or a partner app) enters that Bluetooth radius, the beacon can trigger an action: anything from a personalized message to an automated workflow on the back end.
Beacon technology is already used by some of North America’s top retailers, including Macy’s, Target, Urban Outfitters, and CVS.
The continued rise in popularity is expected to help reinvigorate brick-and-mortar retailers, offering customers customizable shopping experiences that can’t be replicated online.
A beacon sends a tiny Bluetooth signal, a smartphone listens for it, and an app interprets what that signal means.
Here’s the breakdown:
Beacons transmit a small Bluetooth identifier every few milliseconds.
To complete the loop, you need:
Then, when a shopper comes within range:
Beacons run on Bluetooth Low Energy (BLE), a power-efficient variant of traditional Bluetooth designed for short bursts of data transmission. It’s perfect for tiny devices that need to run for months or years on a coin cell battery.
That means:
In the US alone, the BLE market is growing fast, from $2.34 billion in 2024 to a projected $9.05 billion by 2032.
And more importantly: BLE doesn’t track people, it simply broadcasts a tiny ID number. Your app interprets that ID and decides what to do, like show product information or speed up pickup.
Two major beacon protocols dominate retail: iBeacon (Apple) and Eddystone (Google). They both use BLE, but they transmit different types of data and work better in different ecosystems.
Here’s the quick comparison:
| Feature | iBeacon | Eddystone |
|---|---|---|
| Developer | Apple | |
| Best for | iOS-heavy audiences | Mixed iOS + Android environments |
| Data transmitted | UUID + Major + Minor IDs | Multiple frame types (UID, URL, TLM, EID) |
| Notable strength | Deep iOS support; rock-solid app integrations | Can broadcast URLs, diagnostics, telemetry; flexible for analytics |
Retailers often choose based on audience and use case. Many run hybrid deployments so both iOS and Android devices can interpret beacon signals consistently.
Research from The Marketing + Media Alliance shows that beacons enable highly relevant, location-triggered mobile engagements that improve consumer responsiveness compared with generic push notifications, driving stronger engagement in context.
Here’s how proximity marketing technologies empower retailers:
Beacons are basically location micro-signals, allowing you to deliver a personalized customer experience. GPS can tell you that a customer is at your mall, Wi-Fi can tell you they’re in your store, but a beacon tells you they’re at the denim wall, near the pickup counter, or walking past your holiday pop-up.
Beacons shorten the path to what the shopper actually wants. They power aisle-level navigation, notify staff when assistance is needed, guide customers toward curated collections, and streamline BOPIS/curbside workflows.
Because beacons track micro-movements—dwell time, traffic flow, product interaction zones—retailers get insight into what shoppers actually do versus what they say they do. This helps teams optimize merchandising, staffing, store layout, inventory placement, and promotional zones with evidence.
Beacons give your app a job to do. Instead of hoping customers open it on their own, in-store triggers create natural moments of engagement: product discovery, loyalty rewards, mobile checkout prompts, size-availability checks, and in-aisle inspiration.
This is phygital retail in action: the physical journey prompts digital interactions, and the digital data enhances the physical moment.

Walgreens understood early that mobile wasn’t just for “pre-purchase research.” Shoppers were already using their phones in store, they just weren’t using them to check out.
Instead of pushing harder for mobile checkout, Walgreens redesigned its app to support how customers shop in-store. The new app features connect directly with in-store beacons, which ping a shopper’s phone as they pass specific displays. In response, the app surfaces relevant prompts—coupons, limited-time deals, or product information—right when the customer is standing in front of the item.
And while every retailer uses beacons differently, the underlying idea is to meet the shopper where they are and make their next step easier. Here are some practical ways you can use beacons:
Beacons work best when they support a clear retail moment. Here’s how to implement proximity marketing with them.
Begin with a moment in the customer journey that feels confusing or full of missed opportunities.
Ask yourself:
Then, translate that moment into a beacon use case:
This step is less about comparing technical specifications and more about understanding how your store operates day to day.
A good place to start is by thinking about the physical environment. Every store has natural touchpoints: entrances, endcaps, seasonal displays, fitting rooms, pickup counters—where customers pause, look around, or make decisions. Effective beacon deployments build around these moments.
For example, small battery-powered beacons may work well near display tables or shelving, while long-range or plug-in units might be better suited for high-traffic entry areas.
Next, consider how hands-on you want to be with maintenance. Some retailers prefer low-touch beacons that run for a year or more on a single battery, while others choose plug-in or USB-powered options because they fit naturally into existing store fixtures.
The same is true for software. Many retail teams benefit from choosing a provider that offers both the physical hardware and the management platform, so everything can be configured from one dashboard.
These companies are widely used in retail, hospitality, logistics, and large venue environments:
This typically involves integrating the provider’s SDK so the app can “listen” for beacon signals and respond.
For most retailers, this isn’t a heavy engineering lift. The SDK simply gives your app the ability to recognize when a customer is near a specific beacon and connect that location to an action—such as displaying product information, offering a loyalty reward, or notifying staff that a pickup customer has arrived.
This is also a good moment to think about permissions and transparency.
Customers generally respond well when they understand why an app is asking for Bluetooth or location access, and when those permissions clearly improve their in-store experience. A short, friendly explanation inside your app, something as simple as “We use Bluetooth to help you find products and receive relevant offers while you shop,” goes a long way toward building brand trust.
Here, you want to bring the technology into your physical space in a way that feels natural to your shoppers.
The final step is deciding what you want your beacons to do. The simplest approach is to build a few small campaigns that make the shopping experience feel smoother or more helpful.
Start with moments that already matter to your customers, such as:
👉Your rule of thumb: If an interaction doesn’t make the visit easier, it probably isn’t worth triggering.
As these campaigns run, pay attention to the signals your store gives you:
From there, you can refine your timing, adjust placement, or expand into new parts of the store.
💡Pro tip: Shopify Analytics lets you track changes in store traffic patterns, product engagement, loyalty redemptions, or pickup efficiency to understand whether a beacon-triggered interaction is having the intended effect.
Beacon technology has the potential to revolutionize customer communications for brick-and-mortar retailers. Shoppers can enjoy more engaging, seamless, and personalized experiences while you gain customer insights—ultimately making it easier to achieve a number of business goals using a single piece of retail technology.
All three help retailers connect the physical store to a mobile device, but they work in different ways.
Together, these tools support a broader marketing strategy that meets shoppers at different points in their journey.
No, beacons don’t collect personal data on their own—they simply broadcast a small Bluetooth signal. A retailer’s app decides how to interpret that signal and what marketing messages to show.
Customers must grant permission on their mobile devices, and they can opt out at any time. This makes beacons a privacy-aware way for store owners to improve the in-store experience while still respecting choice and control.
Beacon pricing varies by provider, but most standard BLE beacons range from $20 to $40 per device, with enterprise-grade hardware costing a bit more.
Depending on signal strength and configuration, a beacon can run anywhere from one to two years on a single coin-cell battery. Some providers also offer USB-powered or hardwired models for high-traffic areas where constant uptime is essential.
Retail is the most common example. Store owners use beacons to share product details, personalize marketing messages, and gather data on how shoppers move through the space:
