Abstract:
A supermarket or a hypermarket is a form where wide variety of product items
is available. These product items can be food, beverages or any household product.
The main purpose of supermarkets is to provide availability of all the products and
save the time of the customers but sometimes customer gets frustrated while waiting
in the queue at billing counter and sometimes they get confused while comparing the
total price of all the products with the budget in the pocket before billing. To overcome
these problems, we have designed a smart trolley using LCD display and Arduino.
With this system, there is no need for customer to wait in the queue for the scanning
for the product items for billing purpose. Supermarkets provide this for only those
customers which having a token cart. When the customer inserts the token into trolley
only then it will work as a smart trolley. Otherwise, it will work as a normal trolley.
Supermarkets use this technique as a strategy to increase the number of customers.
