RFID-Based Billing System for SM Supermarket Carts

An innovative product with societal acceptance is the one that aids the comfort, convenience and efficiency in everyday life. Nowadays, purchasing and shopping at the malls is becoming a daily activity. People purchase different items and put them in trolley and proceed to the billing counter for payments. The cashier use bar code reader for billing which is a time consuming and usually resulted in long queues. The main goal of this study focuses on the development of RFID – based billing system that helped the customers to lessen their time in the cashier while shopping. This project study was conducted with research and development to investigate and promote an effective and efficient billing system through the application of different technological advancement. The study consists of Arduino Uno and Arduino Mega 2560 powered by a supply voltage of a regulated 6V DC. ZigBee and RFID reader enabled to transmit and/or receive data from the given code of RFID tags. The use of liquid crystal display shows the information of an item scanned by the reader. The designed prototype’s testing has turned out to be successful especially in terms of effectiveness. The users were able to check-out faster that lessen their time in billing. Almost all of the items put in the cart in the actual testing were all read by the system with accurate information. In the evaluation of the prototype, almost all of the respondents strongly agreed that the system’s functionality and efficiency was suited in public use.
