The invention discloses a
radio frequency identification method and
system based on a
wireless communication terminal. According to solved technical problems, an RFID tag function of the
wireless communication terminal is extended; the identification distance of the RFID tag function is increased; and a binding restriction with RFID tag
data information is eliminated. According to the method provided by the invention, the
wireless communication terminal controls an internal switch of a multi-tasking module to switch a
signal path or switch the working state of a
receiver and
transmitter module; the terminating impedance of an antenna changes corresponding to the RFID
data information to carry out reverse scattering communication; and direct extension is carried out to realize the tag function. The antenna of the wireless communication terminal has the advantages of free shape and size design and high
gain, thus the identification distance of the RFID tag function is increased. According to the
system provided by the invention, the RFID tag
data information is updated and generated according to a user need, and is dynamically configured by a networking
server. Compared with the prior art, the method and the
system, which are provided by the invention, has the advantages that the cost of tag integration is saved; the identification distance is increased; the data information binding restriction is eliminated; and economic, flexible and reliable
radio frequency identification is realized.
