Now-a-day shopping in city-mark and mall is increasing rapidly. While shopping, customers have to face some difficulties. First, they go at the billing counter for payments their total expenditure but there are many people standing in queue for billing purpose. This is unnecessary waste time for customer because cashier scans each item bought with barcode. Barcode technology is time consuming process. Second, customer can’t predict their total expenditure so overall purchase total is greater than their budget. Thus, the system overcomes all of these drawbacks faced by customers in shopping malls. This system has been introduced to avoid waiting in billing queue. The system consists of a RFID reader, Arduino Uno, LCD display and wireless Zigbee transmitter in the customer site and software programming language is Arduino IDE. At the counter computer, Zigbee receiver is connected to billing PC using serial communication. Visual Basic 6.0 is used for Graphical User Interface (GUI) to get display customer bill and Microsoft Access database system is used to know about details of purchasing products on the counter computer.
