In metropolitan cities, we will see an enormous rush at shopping malls on holidays and weekends. This becomes, even more, once there are large offers and discounts. Currently folks purchase a spread of things and place them within the trolley, after buying one ought to approach the counter for billing. By employing a barcode reader, the cashier prepares the bill that may be a time overwhelming method. This ends up in long queues at the billing counters. This project presents a plan to build up a framework in shopping centers to beat the above issue. The main purpose of this work is to build an IOT based electronic smart cart system which will introduce an intellectual approach to billing process using pi camera and raspberry pi with image processing. The total bill of e-trolley can be found on the web page.

The major building blocks of the project are:  

1. Power supply.
2. Raspberry Pi processor.
3. Pi Camera.
4. LED Indicator.
5. LCD display with driver.
6. Buzzer.
7. Selection switch.

Software’s used:  

1. Embedded Linux programming.
2. Express SCH for Circuit design.
3. Web technology.
