A complete RFID system consists of Reader and Transponder two parts, the principle of its action by the Reader to launch a specific frequency of infinite wave energy to Transponder, used to drive the Transponder circuit will be sent out of the internal ID Code, at this time the Reader will receive this ID Code. The Transponder's special features include no battery, no contact, no card swipe, no dirt, and the chip code is the only one in the world that can't be duplicated, with high security and long life.
The application of RFID is very wide, at present, the typical application of animal chip, car chip immobilizer, access control, parking lot control, production line automation, material management, RFID tags have two kinds: active tags and passive tags.
The following is the internal structure of the tag: chip + antenna and RFID system composition schematic
2. What is the electronic tag
The electronic tag that is RFID some say radio frequency tags, radio frequency identification. It is a non-contact automatic diagnosis technology, through the radio frequency signal recognition target object and obtains the related data, the recognition work does not need the human intervention, as the bar code of the wireless version, RFID technology has the bar code does not have the waterproof, the anti-magnetic, the high temperature resistance, the service life is long, reads the distance is big, the label on the data can be encrypted, the storage data capacity is bigger, the storage information changes freely and so on the advantages.
2. What is RFID technology?
RFID radio frequency identification is a non-contact automatic identification technology, it through the radio frequency signal automatically identify the target object and obtain the relevant data, identification work without human intervention, can work in a variety of harsh environments. RFID technology can identify high-speed movement of the object and can be identified at the same time more than one label, the operation of the fast and convenient.
Short-range RFID products are not afraid of grease, dust pollution and other harsh environments, can be used in such environments to replace the bar code, for example, used in factories to track objects on the assembly line. Long-range RF products are mostly used in transportation, recognition distance up to tens of meters, such as automatic toll collection or identification of vehicle identity.
4. What is the RFID solution
RFID solution is RFID technology providers for the development of industry-specific characteristics of the RFID application program, according to the actual requirements of different enterprises "tailored".
RFID solutions can be categorized by industry, logistics, anti-counterfeiting and anti-theft, identification, asset management, animal management, fast payment, etc. To view the program please click here.
5. What is RFID Middleware
RFID is recommended as one of the top ten strategic technologies for organizations to consider introducing in 2005, and Middleware can be described as the backbone of RFID operations because it accelerates the introduction of critical applications.
The RFID industry has unlimited potential, with applications in manufacturing, logistics, healthcare, transportation, retail, defense, etc. Gartner Group believes that RFID is one of the top ten strategic technologies that companies can consider introducing in 2005, but the key to its success is the availability of key components in addition to the price of the tags, antenna design, standardization of bands, and certification of equipment. However, the key to its success, in addition to tag (Tag) price, antenna design, band standardization, equipment certification, the most important thing is to have a key application software (Killer Application), in order to quickly promote. And the middleware (Middleware) can be called the RFID operation of the center, because it can accelerate the key application of the introduction.
6. What are the basic components of an RFID system?
The most basic RFID system consists of three parts:
Hashtag (Tag): by the coupling element and the chip, each tag has a unique electronic code, attached to the object to identify the target object; Reader (Reader): read (and sometimes write) tag information device, can be designed for handheld or fixed;
Antenna ( Antenna): between the label and the reader to transmit RF signals.
