Implementation of Wireless Sensor Network to reduce cashier queue

The use of Wireless Sensor Network (WSN) has been widely used in many fields, especially for environmental monitoring. This present study attempts to apply the WSN technology into the retail industry or the modern market. Utilizing barcode scanning technology as a medium of sensors that are commonly used, combined with a microcontroller and XBee modules as data transmission module. This study adds load sensor module on the checkout system based Wireless Sensor Network (WSN) to increase the accuracy of the system during the process of checking out at the cashier. Error processes towards the identification of goods can be reduced, thus the customer queuing time can also be reduced.
