Embodiment Construction
[0020] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0021] figure 1 A structural block diagram of the radio frequency identification tag according to the present invention is schematically shown. Such as figure 1 As shown, a radio frequency identification tag of the present invention is mainly composed of a tag antenna 101 and a micro integrated circuit 102 . Such as figure 1 As shown, the micro integrated circuit 102 is bidirectionally connected with the tag antenna 101 . In particular, according to the general principle of the present invention, the tag antenna 101 can realize non-contact data reading and writing with a radio frequency tag reading and writing device, wherein, the micro integrated circuit 102 is reading and writing with the radio frequency tag reading and writing device. Before the writing operation, identify the ID mark of the radio frequency tag reading and writing dev...

The invention provides a radio frequency identification tag according to one aspect. The radio frequency identification tag comprises a tag antenna and an integrated microcircuit, the integrated microcircuit is in bidirectional signal connection with the tag antenna, the tag antenna can achieve non-contact data reading and writing with a radio frequency identification tag read-write device, and the integrated microcircuit identifies ID (identification) marks of the radio frequency identification tag read-write device and negotiates read-write standards with the same before reading and writing with the same. Besides, the invention further provides a read-write method of the radio frequency identification tag. By the radio frequency identification tag and the read-write method thereof, highly reliable information reading and writing can be guaranteed, and reading and writing efficiency is improved.
Description
technical field [0001] The invention relates to radio frequency identification technology, in particular to a radio frequency identification tag and a reading and writing method thereof. Background technique [0002] Radio frequency identification is RFID (Radio Frequency Identification) technology, also known as electronic tags and radio frequency identification. It is a communication technology that can identify specific targets and read and write related data through radio signals without the need to establish mechanical or optical contacts. [0003] According to the general principle, after the tag enters the magnetic field, if it receives a special radio frequency signal from the reader, it can send out the product information stored in the chip by virtue of the energy obtained by the induced current (that is, Passive Tag, passive tag or passive tag ), or actively send a signal of a certain frequency (ie Active Tag, active tag or active tag), the reader reads and decod...
