RFID (Radio Frequency Identification) certificate verification device

Abstract

The invention discloses an RFID (Radio Frequency Identification) certificate verification device. The device comprises a power supply unit, a control unit, an SAM (Security Access module) card, card readers and antennas, wherein the power supply unit is connected to the control unit and the card readers respectively and is used for supplying power to the control unit and the card readers; the card readers are connected to the antennas, and the antennas are used for receiving signals on an RFID certificate and transmitting the signals to the card readers connected with the antennas; the SAM card is used for realizing bi-directional authenticated encryption between the verification device and the RFID certificate; the control unit is connected to the SAM card and the card readers respectively and is used for receiving the signals transmitted on the SAM card and the card readers, identifying and processing the received signals and realizing corresponding automatic identification of the RFID certificate. According to the certificate verification device disclosed by the invention, a plurality of certificates can be verified by integrating a long-range card reader with a short-range card reader, and the RFID certificates in multiple frequencies are verified; the certificate verification device has an online non-interference automatic fast recognition and verification function.

Description

technical field [0001] The invention belongs to the technical field of radio frequency identification, and in particular relates to the design of certificate verification equipment. Background technique [0002] The Internet of Things has been identified as one of China's strategic emerging industries, and Radio Frequency Identification (RFID) is the most critical technology for the development of the Internet of Things, and its application market will surely expand with the development of the Internet of Things. RFID is a non-contact automatic identification technology. It automatically identifies the target object and obtains relevant data through radio frequency signals. The identification work does not require manual intervention and can work in various harsh environments. [0003] In civil aviation airports, military sites and other places, in order to ensure the safety of personnel entering and exiting, it is necessary for the personnel entering and exiting to verify t...
