Automatic shopping trolley for commodity location and price checkout.

Abstract

In Uganda today, the average time wasted by supermarket clients to identify the exact location of the desired commodity and queue to make payment is definitely plenty. The customer searches for the required commodities through the different aisles to various sections and drop all the products they wish to purchase in the trolley/basket, and then they proceed to the checkout queue for billing. There is also unnecessary time wasted on the billing counters. Therefore, the system developed enables the customer to easily know the location of the commodity, price checkout as well as billing of the commodity. The system consists of the touch screen monitor which displays the location of the desired commodity in the shopping arena. The customer moves to the section, and he picks the commodity which has rfid tags attached on it and drops it into the trolley via the reader, the tag is sent to the central database, the price, name of commodity and cumulative total price are displayed on to the touch screen monitor as more commodities are added. The information is stored in system's database and it is also displayed on the computer at the cashier’s desk. If an unwanted product is removed from trolley, then that commodity is also deleted from the database.
