Abstract

A futuristic shopping complex is not only a place to shop but it demands an innovative and high technology that aids the convenience, efficiency and effective style in daily life. On the other hand, shopping activities can be a time consuming especially during special offers, discount provided on various products and large crowd on weekends, which a lot of people need to face a long queue to make the payment. However, the existing way of calculating the total amount of items produced several problems for instance expensive devices, non-accurate amount of calculation and non-user-friendly interface system. Therefore, the idea for Smart Shopping Cart is introduced to reduce the time spending on queue and smoothen the billing process, which the bill can be calculated expeditiously with exact price of product according to its current market rate. Studies have shown that there are three methods used on smart shopping cart, which are server based cart, cloud based cart and Bluetooth based cart. Server based and cloud cart is using shopping cart with RFID but the cost is expensive because it needs alternative hardware to build with it. In contrast, the Bluetooth based cart uses cart with RFID but it causes a mesh during data transmission as it transmits data in a long distance. Thus, there are few objectives for this project development, which are a)to study the NFC based shopping cart at the shopping mall, b)to design automatic bill calculation interface for smart shopping cart and c)to implement the new bill calculation interface based on NFC for smart shopping cart system. As a result, the effect of this study will provide a future shopping platform to be a possible solution.
