        RFID tags

        RFID radio frequency identification technology basics:

        RFID technology (Radio Frequency Idenfication, RFID) is a non-contact automatic identification technology, the basic principle is the use of radio frequency signals and spatial coupling (inductive or electromagnetic coupling) or the transmission characteristics of radar reflectivity, the realization of the object to be identified automatic identification.

        RFID system contains at least electronic tags and readers in two parts. Tag is a radio frequency identification system data carrier, the electronic tag from the tag antenna and tag-specific chips. Based on the different ways of power electronic tags, electronic tags can be divided into active RFID (Active tag), passive electronic tag (Passive tag) and semi-passive RFID tags (Semi-passive tag). Active tag has a battery installed, passive RF tag is not built-in battery, semi-passive RFID tags (Semi-passive tag) relies in part on battery.

        RFID tags can be classified according to different frequenciesLow-frequency electronic tagsHigh-frequency electronic tagsUHF RFID tagsANDMicrowave electronic tags。Based package can be divided intoCredit card labelLinear tagPaper-like tagGlass labelRound TagAnd special purposeAlien tagsETC.

        RFID reader (reader) through the antenna and the RFID tag for wireless communication, can be achieved for tag identification code and the memory data read or write operations. A typical reader includes a high-frequency module (transmitter and receiver), the control unit and the reader antenna.

        Seven advantages of RFID electronic tags

        Compared to the traditional barcode recognition technology, RFID has the following advantages:

          1.Quick Scan
          Only one barcode bar code is scanned; RFID reader reads several simultaneous identification RFID tags

         2.Small size, shape diversification
          RFIDThe reading is not limited by the size and shape, and no precision in order to read the paper with a fixed size and print quality. In addition, RFID tags but also to the development of smaller and more diverse forms to apply to different products.

          3.Contamination resistance and durability
          The carrier is a conventional bar code paper, therefore susceptible to contamination, but RFID for water, oil and chemicals and other substances with a strong resistance. In addition, since barcodes are attached to plastic bags or cardboard packaging, it is particularly vulnerable to breakage; RFID label is the data in the chip, it can be free from fouling.

          4.Reusable
          Today's bar code can not be changed after printing up, RFID tags can be repeated to add, modify, delete data stored on RFID tags to facilitate information updates.

          5.No barrier penetration and reading
          In the case of being overwritten, RFID can penetrate paper, wood and other non-metallic or non-transparent plastic material, and be able to communicate penetrating. The bar code scanner must be in close proximity and no objects blocking the case can only be readable barcodes.

          6.Data memory capacity
          The capacity of one-dimensional barcodes 50Bytes,Maximum storage capacity for storing two-dimensional barcode 2-3000 characters, RFID maximum capacity is several MegaBytes. With the development of the memory carrier, the data capacity is also growing trend. Future articles will be required to carry the amount of data increases, the volume label can expand capacity on demand also increased.

          7.Security
          Because RFID is the bearer of electronic information, the data content via password protected, so that its contents can not easily be forged and altered.
          In recent years, RFID read its possess long-range, high storage capacity and other characteristics have attracted much attention. It not only helps a substantial increase in cargo business, information management efficiency, but also allows sales companies and manufacturing enterprises interconnection, and thus more accurately receive feedback information, control demand information, optimize the entire supply chain.
