  With RFID technology, STAR TREND offers more solutions for RFID door access control than RFID cards . It can be RFID keyfobs,wristbands, RFID tags or labels complying with the LF/HF/UHF system. All the RFID products are widely used in restricted area as hotels, residential and private clubs.   How Does RFID Based Door Access Control Work?   The basic working principle of rfid based door access control system   is not complicated: RFID readers send out radio frequency signals after receiving instructions. When the RFID cards enter the magnetic field, they receive radio frequency signals from the readers and send out the product information ; after the reader reads the information and decodes it, it is sent to the information system for relevant data processing. Its working principle is that the reader transmits a specific frequency of radio wave energy to the transponder then drive the transponder generate circuit to send out the internal data. At this time, the Rea...

  The radio frequency identification card is mainly produced by contactless IC card identification technology. Not only certain technical support is required, but also strong card-making equipment is needed to ensure that no mistakes are made in the process of making RFID cards.   Radio frequency cards are divided into low frequency cards and high frequency cards ( hf card ). The low-frequency RFID technology below 13.56MHz has accumulated more than 10 years of mature experience in the industry. At present, the RFID technology located in the middle and high frequency bands is the most concerned in the industry. In the field of high frequency, domestic companies have gradually matured their technologies and are actively promoting the application of various systems. At present, the demand for RFID cards  in China is very large!   As a more sophisticated product in the smart card, the RF card is currently used in traffic management, security system, personnel attendance...
