Description

External reader-writer

Technical Field

The utility model particularly relates to a read write line equipment technical field specifically is an external read write line.

Background

The reader/writer is also called interface device ifd (interface device), card receiving device CAD, coupling device CD (coupling device CCD close coupling device PCD, loose coupling device VCD, terminal CAD), etc. The reader is generally regarded as a read-write terminal device of radio frequency identification, namely RFID. It can not only read the radio frequency label, but also erase and write data, so it is called reader-writer. An IC card reader/writer is an important device for realizing data communication between an IC card and a system. The general-purpose IC card reader is capable of performing operations such as reading, writing, and erasing of IC card information, and has a function of communicating with external devices such as a computer, a MODEM, and a terminal mouth.

A reader-writer, i.e. a radio frequency tag reading-writing device, is one of two important components (a tag and a reader-writer) of a radio frequency identification system. The rf tag read/write device has some other popular alternative names according to the specific implementation functions, such as: reader (Reader), Interrogator (Interrogator), Communicator (Communicator), Scanner (Scanner), Reader and Writer (Reader and Writer), Programmer (Programmer), Reading Device (Reading Device), Portable Reader (Portable Reading Device), AEI Equipment (Automatic Equipment Identification Device), etc. In general, the rf tag reader/writer device should be designed according to the reading/writing requirement of the rf tag and the application requirement. With the development of the radio frequency identification technology, radio frequency tag reading and writing equipment also forms some typical system implementation modes, and the focus of this chapter is also to introduce the implementation principle of this reader.
