Abstract

The present invention relates to a radio frequency identification apparatus for identifying a radio frequency identification label by a radio frequency identification reader, and comprises a reading unit and a label unit. The reading unit includes the radio frequency identification reader and a first permanent magnet of first magnetism. The label unit includes a radio frequency identification label, a second permanent magnet of second magnetism, a spring device for connecting the second permanent magnet and the radio frequency identification label, and an electromagnet. Thereby, a radio frequency identification label exceeding an identification distance of the radio frequency identification reader is identified, so as to obtain an equal effect of enlarging the identification distance of the radio frequency identification reader. In addition, an operator is capable of determining whether the radio frequency identification label is identified or not through vision by moving the radio frequency identification label.

Description

technical field [0001] The invention relates to a radio frequency identification device, in particular to a radio frequency identification device for identifying manual radio frequency identification tags. Background technique [0002] Chips built into radio frequency identification tags (Radio Frequency IDentification Tag, RFID tags) and radio frequency identification readers (Radio Frequency-IDentification Readers, RFID readers) are being mass-produced, and the transmission and reception performance of the chips has been determined. Furthermore, an international standard has been set for the transmission output of the radio frequency identification device using an ultra high frequency (UHF) band frequency. [0003] Therefore, there is a problem that it is difficult to increase the recognition distance at which the RFID reader can recognize the RFID tag. Contents of the invention [0004] The purpose of the present invention is to extend the identification distance of a ...
