The traditional shopping system has a trolley which will make the customers feel heavy to push the trolley with the items. This conventional shopping system aids the customers by autonomously following the customer who is shopping with that trolley. Another convenience is with the trolley is that it calculates the net amount of shopping items by scanning the RFID tag and RFID reader attached with the trolley. The trolley follows the customer with the frequency range of Wi-Fi connected to the mobile phone of the customer and it avoids the obstacles in its way. Wi-Fi is the IEEE 802.11 standard. The RFID tag is on the packet of each items and the code is read with the RFID reader. The unique RFID tag in each item has the information of that item and it is read with the RFID reader. The cost of the item can be read and the amount is displayed in the LCD screen and it speeds up the billing process. So, the customers can save their time in the billing counter rather than waiting for a long time in a queue to pay the bill. This system helps the customers enjoy shopping and shortens time spent for shopping.
