Wireless Sensor Networks are being used in environment that was impossible earlier. WSNs are applicable in battlefield monitoring, underwater deployment and vehicle tracking. Applications areas and security features can be expanded many folds by integrating WSNs and RFID technology. The tracking network is being explored further with these new emerging technologies. This integrated technology enhances secure way to electronically follow an object. To make such tracking network RFID readers are experimented with Freescale Zigbee boards. This network would be able to track unique object passing nearby to the readers
