The related technologies of radio frequency identification (RFID) applications are interested these years. The reason is the breakthroughs in semiconductor and wireless technology, so that the size of RFID devices could be reduced within a small space. Thus for different application scenarios, RFID devices could be redesigned as various forms or behaviors to adapt. The more added values provided by the RFID characteristic, the batter RFID applications are expected to compete with bar-code system in the future. In this paper, the RFID system has also been applied in vehicle information communication safety which uses wireless communications to provide passenger information and services. In this paper, the vehicle safety combined with mobile RFID system, which includes five functions. The system composed of small tags embedded around vehicle, scanners also known as reader, Geographic Information System (GIS), mobile devices and Electronic Product Code (EPC) middleware. The middleware function is implemented to drive reader and connect server. The program of the system development has been ensured safety of passenger and vehicle safety real time.

This paper proposes a new application framework for group tour guiding services based on RFIDs and wireless sensor network. We consider a sensing field mixed with multiple independent tourist groups, each with a leader and several members. Members of a group will follow the moving path of their leader, but may occasionally roam around randomly based on their interest. Sensor nodes have to track leaders' locations and maintain following paths from members to leaders. A member may ask where his/her leader is, and a leader may "recall" his/her members. We propose a feasible solution to such an application by using existing technologies. A group guiding protocol is presented. The design enables reliable group guiding at low cost and low traffic load.

Our conventional postal systems are inefficient, difficult to track and slow in service. This project provides a solution for improving postal services enabling Secured Postal Data Communication with the help of RFID technology which is one of the best proved wireless technologies. The main concept of this project is to keep track of the post from the dispatch place until it reaches the designated person. When the courier/post is transported from one location to other location, its current location will be updated to the recipient of the courier with the help of GSM and GPS. The usual practice of sticking the stamps on the each postal cover will be replaced by passive RFID tags.

An embedded system is a special-purpose computer system designed to perform a dedicated function. Since the system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product. Embedded system comprises of both hardware and software. Embedded system is fast growing technology in various fields like industrial automation, home appliances, automobiles, aeronautics etc. Embedded technology uses PC or a controller to do the specified task and the programming is done using assembly language programming or embedded C.The Consumer Electronics is the essential part of the Embedded System to help the people. An average person uses about 50 Embedded System every Day. It mainly used in automation for the home people. In day today life we are using many hidden embedded products like washing machine, mobile, TV remote etc.

The proportion of air pollution which is caused by the cars is increasing. In order to solve this serious problem, many countries and regions have already presented a series of emissions standards, meanwhile some methods has been developed, include update motor engine or improve the quality of the gasoline. However, these actions have not brought about a striking effect as we expect. There are also some situations to fail implement these emissions standards. In this paper, a wireless inspection and notification system (WINS) through the concept of Internet of Things (IoT) is proposed. By applying the system, it is possible to smoothly realize a green traffic network. In this system, Radio frequency identification (RFID) technology as a low-cost and mature wireless communication method is adopted to collect and transmit emissions information of vehicles. Moreover, The RFID devices need to be installed on the traffic lights so that reliable reading of emissions signals from a vehicle can be interrogated when the vehicles stop in front of the red light. Taken into consideration the real environment, an efficient and innovative maximum spanning tree algorithm (MXAST) is also presented to select suitable traffic lights aim to reduce the number of RFID devices (more economy) and guaranteed the whole urban cars can be monitored (simple & safety).
