IoT Applications in Retail

Retailers have quickly realized IoT‘s immense potential to provide operational visibility, enrich customer experiences and disrupt nearly every aspect of the retail value chain. Leveraging connected smart devices allows retailers to enable capabilities that simply weren‘t possible in the past.

While the consumer-facing side of retail IoT gets the most attention, the behind-the-scenes applications that enhance logistics, inventory, facilities management and overall operations have the biggest monetary impact for retailers.

Let‘s explore some of the most common and impactful retail IoT use cases:

Supply Chain Visibility

Outfitting pallets, shipping containers and trucks with sensors allows retailers to gain granular visibility into their supply chain flow. GPS and RFID tags enable retailers to track locations and conditions of in-transit merchandise 24/7. Environmental sensors can even detect instances of theft, damage or spoilage.

This supply chain transparency allows retailers to identify shipping bottlenecks, optimize delivery routes, prevent product loss, improve forecasting, and meet SLA goals. According to an Auburn University at Montgomery study, real-time visibility into supply chain conditions using IoT reduces costs by 65.6% on average.

Automated Inventory Management

IoT is enabling retailers to automate inventory tracking across their extended supply chain in ways never possible before. Connected cameras, digital weight sensors, RFID readers and other in-store sensors can continuously monitor product availability on shelves and in storage rooms.

This allows retailers to cut down on manual stock checks by staff. More importantly, the real-time inventory data enables intelligent re-ordering and restocking to prevent costly out of stocks. Research suggests product availability is one of the biggest drivers of customer satisfaction and loyalty for retailers.

Smart Shelves

Moving beyond simply tracking inventory, some retailers are implementing "smart shelves" to create a fully IoT-enabled product replenishment process.

Shelves are equipped with a combination of LED displays, motion sensors, weight sensors and RFID readers. As soon as a product is picked up by a shopper, the shelf sensor detects the now empty spot. The LED display gets updated in real-time, staff get notified, and replacement inventory is automatically ordered.

This smart shelf technology prevents overstocking and reserves shelf space for the most in-demand items to maximize sales.

Predictive Equipment Maintenance

Sensors embedded in refrigeration systems, HVAC units, electronic displays and other in-store equipment can continuously monitor performance and relay data like temperature, pressure, humidity, vibrations and energy consumption.

Analyzing this data allows retailers to identify anomalies and predict potential equipment failures before they cause disruptions. This shift from reactive to proactive maintenance saves retailers money and keeps operations running smoothly.

Enhanced In-Store Experiences

IoT deployments allow brick-and-mortar retailers to provide the kinds of frictionless, personalized shopping experiences that consumers have come to expect from ecommerce giants like Amazon.

In-store sensors can track real-time customer foot traffic, dwell times, and popular product engagement. This was nearly impossible to monitor in the past beyond anecdotal observation by staff. The shopper insights unlocked by IoT data allow retailers to improve store layouts, placement strategies, staffing levels and services.

IoT can even enable smart features like digital mirrors that allow shoppers to digitally try on clothes, or receive customized offers for nearby products via their mobile app when entering certain departments.

Mobile Payments

46% of shoppers say waiting in long checkout lines is their least favorite part of shopping. IoT-enabled mobile payments help solve that.

Retailers can allow shoppers to pay directly from their app using short-range wireless protocols like RFID and NFC to communicate with sensors placed around stores. This means no more waiting in line for a cashier.

Mobile payments also allow easier integration of loyalty programs and personalized offers to influence buying decisions at the point of sale.

Loss Prevention

Shoplifting costs retailers tens of billions per year. IoT technology like sensors and high resolution security cameras with object and facial recognition capabilities can help identify suspicious behavior and known thieves as soon as they enter stores. This real-time monitoring capability vastly improves theft prevention.

Analytics on sensor data further enables retailers to pinpoint high-risk departments, times of day, and stores to allocate loss prevention resources most effectively.

Contextualized Marketing

Beacon and sensor technology allows retailers to detect customers‘ locations and behaviors in real-time as they move about brick-and-mortar stores. Retailers can use these insights to trigger relevant offers directly to shoppers‘ mobile apps when they enter certain departments or aisles.

This contextual promotion capability provides a more personalized experience and higher conversion rates than generalized ads.

There are certainly many more potential applications as retailers get creative with IoT. But these use cases have the most transformative power right now to solve persistent operational pain points while future-proofing stores with data.
