Fast Warehouse Management System (WMS) using RFID Based Goods Locator System

In rapidly growing e-commerce businesses, searching purchased items in the warehouse and delivering them within a very short time becomes a crucial problem. In order to solve this problem, we propose a complete RFID based goods locator system which consists of specially designed RFID reader and an integrated cloud based Warehouse Management System (WMS). The RFID reader is able to detect and sense the distance to the location of the purchased item which is attached with a RFID tag based on its RSSI information. The RFID reader is connected with the WMS application installed in a smartphone, through a Bluetooth connection. To update the inventory item information in real time, the Android based WMS application is connected to cloud based logistic and commerce database. Hence, by using this system, the time needed to search the purchased item and track the item delivery status can be shortened. As the result, it increases the efficiency of WMS system.
