Imagine a shopping experience where you could simply walk into a store, select the items you want, and leave without waiting in line or going through a human-driven check-out process. Sounds like a dream, right? After all, on average, we spend 118 hours per year waiting in store cashier lines!
What if you could integrate cutting-edge technologies like Machine Learning (ML), computer vision, and AI into the very fabric of your retail store, eliminating the need for queues? This is exactly what checkout-free shopping offers and it is here to revolutionize how we shop.
RBR research suggests that 20+ countries have frictionless checkout-free stores worldwide, with the number of such stores predicted to reach over 12,000 by 2027. In other news, trials of Verizon’s 5G Edge Cashierless Check-out have observed a 78% increase in transaction count and a 50% reduction in customer transaction lines.
But what do these checkout-free systems do exactly? In this blog, we explore their transformative potential and how IoT plays a role here:
What is check-out free shopping?
Checkout-free shopping, also known as cashier-less shopping or frictionless shopping, is a modern retail concept that utilizes the Internet of Things (IoT), machine learning, AI, and sensor fusion to enable customers to select and purchase items from a store without the need for traditional check-out processes.
The core technology behind checkout-free shopping comprises the following components to process transactions, generate invoices, and handle billing seamlessly:
1. Machine vision
Cameras and image recognition software track and identify products customers choose in the store, analyzing images to identify specific items.
2. QR codes
Square-shaped barcodes are displayed on product packaging or signage that customers scan using a mobile app. Scanning QR codes adds items to the virtual cart, allowing the system to track selections and calculate the total cost.
3. Smart carts
Equipped with advanced technology, smart carts track items placed inside using sensors or RFID tags. The cart updates the virtual cart in real-time, and at the end of the trip, the system calculates the total cost and bills the customer accordingly.
How does checkout-free shopping work?
Retailers are embracing the technology to optimize transaction efficiency and elevate the overall user experience. Here is a step-by-step explanation of how checkout-free shopping typically works.
1. Account setup
Customers need to create an account with the checkout-free shopping service or app. This account is linked to their payment information and serves as their digital identity during the shopping experience.
2. Store setup
The retail store implementing checkout-free shopping must install IoT sensors and cameras throughout the premises. These sensors are typically placed on shelves, ceilings, or other strategic locations to track customer movements and item interactions.
3. Item recognition
Computer vision technology identifies and tracks the items customers select. As each item in the store is equipped with tags or labels, often using RFID or similar technologies, cameras, and sensors in the store capture and analyze these tags to determine which items customers pick up, put back, or add to their smart shopping cart.
4. Sensor fusion and tracking
The data from multiple sensors and cameras are combined to create a detailed picture of the customer’s actions and location within the store. Sensor fusion algorithms help merge information from different sources, enabling accurate tracking of items and customers.
5. Virtual cart creation
As customers add items to their physical carts or baskets, the system creates a virtual cart associated with their account, which is continuously updated based on the data from the sensors, reflecting the changes in the items being carried or put back.
6. Automatic payment
When customers have finished shopping, they can simply exit the store. The system automatically calculates the total cost of the items in their virtual cart based on the captured data. The payment is processed through the customer’s linked payment method, such as a credit card or mobile wallet, without manual intervention.
7. Digital receipt
After the payment, customers receive a digital receipt on their app or via email with a summary of their purchases.
The pivotal role of IoT-based checkout-free shopping
IoT provides the necessary infrastructure and connectivity for a seamless and automated shopping experience. Here are the top benefits of checkout-free shopping powered by technology:
1. Stronger security
IoT-enabled checkout-free shopping systems incorporate various security measures to prevent theft and fraud. For instance, computer vision technology tracks customers and their selected items throughout the store, ensuring that all items are accounted for during payment.
Additionally, sensors and cameras can detect suspicious behavior, triggering alerts or notifications to store personnel or security personnel.
2. Tracking inventory
IoT devices like RFID tags or smart shelf sensors enable real-time inventory tracking. They can monitor stock levels, automatically update inventory records, and alert store managers when items need restocking. This eliminates manual inventory counting, as the system automatically credits the supplier for the added products and reduces out-of-stock situations.
3. Real-time data analysis
IoT solutions and sensors integrated into checkout-free shopping systems continuously collect and analyze data on customer behavior, product popularity, and inventory levels. The technology offers comprehensive analytics, capturing valuable data such as the time customers spend viewing products, selecting items, and returning them to the shelves.
4. Enhanced customer loyalty
Checkout-free shopping eliminates the need for waiting in line, scanning items, and processing payments. Customers can simply pick up the items they want and leave the store, resulting in a faster and more convenient shopping experience. This frictionless process leads to increased customer satisfaction and loyalty.
5. Capturing customer behavior
Similarly, cameras and sensors gather data on customer behavior, such as movement patterns, dwell times, and product interactions. This data provides valuable insights into customer preferences and shopping habits, enabling retailers to make informed decisions about product assortment and marketing strategies.
6. Making personalized recommendations
IoT technology and AI algorithms enable retailers to deliver personalized recommendations based on customer preferences and shopping history. By analyzing data from IoT devices, they can offer tailored product suggestions, promotions, and discounts and enhance customer satisfaction.
7. Optimized store layouts and product placements
Retailers can analyze customer traffic patterns and product popularity heatmaps with IoT-powered analytics. This information helps optimize store layouts and determine the most effective placement of products to enhance customer engagement and drive sales.
They can create open and dynamic store designs by removing the need for traditional check-out counters and focusing on product displays, experiential areas, and customer engagement zones.
