We all know, the Olympics is the world's most ambitious and comprehensive sporting event, set sports, leisure, communication, play, shopping and other commercial activities in one, so carrying the Olympic venues of this event will accept a large audience , athletes, Management Personnel and service personnel, and people as extremely complex and in constant movement among. How to verify that the votes held by persons cards and certificates valid? How to check whether the staff time to track and into the designated area? When the officer strayed into prohibited or illegal intrusion into the area but how do its rapid departure warning and guidance? How to check a real-time regional staff crowding? Use RFID Electronic ticket management system, will be able to achieve high efficiency and quality management purposes. RFID electronic ticket is a smart chip embedded in the medium such as paper tickets, for quick check-in / recount and to achieve accurate real-time location tracking holder and query management, a new ticket. 2008 Beijing Olympic Games will use the RFID chip technology based on electronic tickets, a vivid manifestation of "Technology Olympics" and "Olympics" of profound meaning. I order the RFID information for you print reference. 1. What is RFID RFID stands for Radio FrequencyIdentification is that radio frequency identification. Often called on Electronic chip or proximity cards, proximity cards, contactless cards, electronic tags, electronic bar codes and so on. A complete set of RFID system consists of two parts Reader and Transponder, the movement of a particular principle grounds Reader launch radio frequency energy to the Transponder, Transponder circuit to drive inside the IDCode sent, then Reader will receive this IDCode. Transponder is a special battery-free, non-contact-free card so afraid of dirt, and chips can not copy the password for the world's only high security, long life. RFID is sometimes called the electronic label, RF label. In this non-contact automatic identification technology, as a wireless version of the bar code, is widely used, such as animal chip, access control, parking control, production automation, materials management. Label According to the different types of businesses can store from 512 bytes to 4 megabytes of data ranges. Label data stored by the system application and the corresponding standard decision. For example, the label can provide production, transportation, storage conditions can also identify machines, animals, and individual identity. Label can also connect to the database, storage inventory number, current location, status, price and lot number information. Accordingly, the RF label to read the data in the database can be directly determined without reference to the meaning of the code. Basic RFID system consists of three parts: tag (Tag): the coupling components and chips, and each label has a unique electronic code, attached to identify the target object; reader (Reader) : read (sometimes also written) device label information can be Design For the handheld or fixed; antenna (Antenna): the label and the radio frequency signal transmission between the reader. RFID system includes at least electronic tags and readers in two parts. E-label is a radio frequency identification system data carriers, electronic label and the label by the label antenna dedicated chips. Electronic label according to the different power supply, electronic label can be divided into active electronic label (Activetag), passive electronic label (Passivetag) and semi-passive electronic label (Semi? Passivetag). Active electronic label that has the battery, no built-in battery passive RFID tags, semi-passive electronic label (Semi? Passivetag) relies in part on battery life. Electronic label according to the different frequencies can be divided into low-frequency electronic label, high-frequency electronic tags, UHF and microwave electronic tags electronic label. Based packages can be divided into credit card label, label alignment, paper-like labels, glass labels, round labels and special purpose shaped labels. RFID reader (reader) through the antenna and the RFID electronic tags that wireless communications can be achieved on the label ID and memory data read or write operation. The typical reader contains high-frequency module (transmitter and receiver), the control unit and the reader antenna. 2.RFID History RFID is the direct successor of the radar concept 1948, Harry Stockman published "Using reflective power of communication," laid the theoretical basis of radio frequency identification RFID. RFID technology and applications in China have developed rapidly. In June 2006 by the National Science and Technology, Ministry of Information Industry jointly prepared by more than 10 ministries, "China Radio Frequency Identification (RFID) Technology Policy White Paper" published. The White Paper, presented the general timetable for China's standard-setting: the cultivation period (2006-2008), according to the national RFID standard system framework, to develop appropriate technical standards and application standards; in the growth phase (2007-2012), the basic the formation of the Chinese RFID standard system.
