Future scope

The smart shopping trolley has a high beneficiary future aspect. the project can be modified for better performance in several categories.

the trolley can communicate with the cloud platform and mention the activity it is performing, like moving to the stack, or stooped due to the presence of an obstacle. this will enable the administrative staff knows about the function of the trolley. the trolley can be modified so that it can detect obstacles and behave with the presence of obstacles without disturbing them. 
The smart shopping trolley can be equipped with RFID  sensors so that the trolley can be tracked more efficiently by the administrative staff. RFID sensors and tags can be used to detect the product chosen by the customer. this will help to analyze the shopping activities of customers and gather data about people thoughts on various products. RFID sensors will also enable the trolley to calculate the bill itself. this will save customers time from standing in the queue while checking out. 

Furthermore, the trolley can be controlled from the dashboard by the administrative staff by using two-way communication of the cloud platform. In this project only one-way communication, which means the dashboard could receive information from the sensors through ESP8266.
