Abstract

The invention discloses a radio frequency identification (Radio Frequency Identification, RFID) reader / writer. The RFID reader / writer includes a main body and a first connection part and a second connection part respectively provided on both sides of the main body. The first connection part The second connection part can be connected to the second connection part of another RFID reader and writer, thereby being connected in series with another RFID reader and writer. The invention also provides a radio frequency identification system using the radio frequency identification reader and writer.

Description

technical field [0001] The invention relates to radio frequency identification (Radio Frequency Identification, RFID) technology, in particular to an RFID reader-writer and an RFID system having the RFID reader-writer. Background technique [0002] RFID technology is an automatic identification technology based on the principle of radio frequency identification, which has been widely used in personnel management, warehouse management, transportation and other fields. RFID systems usually include electronic tags, readers and data processors. The electronic tag is used to store item or personnel data. The reader can collect the data stored in the electronic tag within the sensing range and send it to the application system such as the data processor. As the main channel connecting the back-end data processor and the front-end electronic tag, the reader-writer plays a pivotal role. [0003] However, when most existing readers collect data stored in electronic tags, the effec...
