Every good product marketer knows; the only thing better than acquiring new customers is retaining existing customers. Personalized retention marketing can grow customer’s lifetime value and customer retention rate.

Personalization strategies help improve customer value and boost loyal customers. They’re also more cost-effective than customer acquisition strategies. Help customers gain full value from the product is key. 

  • How can a personalized experience help drive retention?
  • What personalized customer retention strategies are open to retailers?
  • What tools can help retailer personalize the customer experience?

Shopping malls and retailers have been looking for innovative ways to provide a more personalized shopping experience to attract and retain customers. One such solution is smart human-following shopping trolleys.

Smart cart to follow customers

Smart human-following shopping trolleys are designed to follow customers automatically, eliminating the need for them to push the cart manually. This technology offers convenience and ease for shoppers, allowing them to focus on shopping and enjoying their experience. The smart trolley is equipped with various sensors and cameras that can detect the customer’s location and follow them while they shop.

Advantages of the smart cart

A more personalized shopping experience. One of the primary advantages of smart human following shopping trolleys is that they provide a more personalized shopping experience. Shoppers can easily navigate through the store without the need to push their trolley or worry about losing it. They can focus on the products they want to purchase and spend more time browsing without any hassle.

Help customers with disabilities. Another advantage of smart human following shopping trolleys is that they can help customers with limited mobility or disabilities. For these customers, pushing a shopping trolley can be challenging, and the smart trolley provides a solution that can make shopping easier and more enjoyable.

More efficient shopping experience. Furthermore, smart human following shopping trolleys offer a more efficient shopping experience. Customers can quickly find the products they want, place them in their trolley, and move on to the next item without the need to keep track of their trolley. This means that customers can shop more efficiently, saving time and reducing the stress associated with shopping.

In conclusion, smart human following shopping trolleys are a promising solution for shopping malls looking to provide a more personalized and efficient shopping experience for their customers. With this technology, shoppers can enjoy a hassle-free shopping experience, and shopping malls can differentiate themselves from their competitors, attract more customers and retain them in the long run.

Smart cart: how does it work

The trolley robot makes use of IR Sensors, Ultrasonic sensor, motor drivers and DC motors all interfaced with an Atmega 328 Microcontroller in order to make this system work.

The robot body is integrated with a mesh based trolley to form a steel basket. This robot mounted basket allows the robot to carry products similar to a shopping trolley.

The robot is integrated with 4 x DC Motors with wheels. This allows for easy 4 WD movement of the robotic vehicle.

The Atmega controller uses motor drivers to drive the 4 motors. The robotic vehicle has 2 IR sensors mounted at the bottom to achieve line follower mechanism.

The robot can move along the line for easy navigation along the shopping racks lane. The robotic vehicle also has an ultrasonic sensor mounted towards the front of the robot. The sensor is used to detect the distance between the user and the robot. The robot keeps following the customer at certain distance as customer moves through the shopping lane. Thus the system puts forth a smart shopping trolley for modern shopping malls.
