Smart Cart

Recent trends use Radio Frequency Identification (RFID) technology in day to day life. They are the ubiquitous tool available for monitoring any item in various fields. RFID technique is mainly used for the security, tracking and monitoring purposes in the tollgate transactions, bank locker security system, automatic vehicle speed control and library books security system. The communication using RFID is in the wireless manner and does not require line of sight. Application of RFID results in automation of huge and complex systems. One of the interesting applications of RFID is an automated shopping cart. Now-a-days, the billing process is highly time consuming and has created the need for shops to employ more human resource in the billing section, but yet, the waiting time remains considerably high. Hence, we propose the “Automated Shopping Cart” as a solution to the above problems. The “Automated Shopping Cart” is simply a trolley or a hand – held cart at a store, which has fixed in it an RFID reader that interacts with an Arduino UNO Controller. RFID tags are attached to every product available for sale at the store. As items are added into the cart, they are detected by the reader and their prices are summed up incrementally. On completion of the purchase and reaching the billing point, the calculated total amount for the respective customer can be transferred wirelessly to the cashier's PC for bill generation and subsequent payment of the bill. A copy of the same is sent via an SMS to the customer's mobile using GSM. This system is expected to speed up all the transactions, improve business for the shopping stores as well as ease up and cut down the time of the entire shopping process for the customers, especially in today's fast moving busy world.
