Conceptually, Proximity RFID Card is similar to barcode scanning. For barcode technology, RFID is used to attach the encoded barcode to the target, and a dedicated scanning reader is used to transmit the strip magnetic information to the scanning reader/writer; The RFID reader and the dedicated RFID tag that can be attached to the target object transmit the information to the RFID reader through the RFID tag through the frequency signal.
In the technical field, a transponder initially refers to an electronic module capable of transmitting information reply information. In recent years, with the rapid development of radio frequency technology, transponders have a new saying and significance. Also known as smart labels or labels. The RFID tag reader wirelessly communicates with the RFID tag via an antenna. RFID technology can recognize high-speed moving objects and identify multiple tags at the same time, which is quick and easy to operate.
The transponder consists of an antenna, a coupling element, and a chip. Usually the tag is used as a transponder. Each tag has a unique electronic code attached to an object to identify the target object.
Reader: A device consisting of an antenna, a coupling element, a chip, and a read (and sometimes writeable) tag information that can be designed as a handheld RFID reader/writer or a fixed reader/writer.
Application software system: It is the application layer software, which mainly processes the collected data for further use.
The reader can be a read or read/write device depending on the structure and technology used, and is an Customized UHF RFID Sticker information control and processing center. The reader usually consists of a coupling module, a transceiver module, a control module, and an interface unit. The half-duplex communication is generally used for information exchange between the reader and the transponder, while the reader provides energy and timing by coupling to the passive transponder. In practical applications, management functions such as collection, processing, and remote transmission of object identification information can be further implemented through Ethernet or WLAN. The transponder is the information carrier of the RFID system, and the transponder is mostly composed of a coupling element (coil, microstrip antenna, etc.) and a microchip to form a passive unit.
