Metal matter, metal causes additional parasitic capacitance, that is, energy loss caused by electromagnetic friction caused by metal, which causes detuning between the RFID UHF reader and the tag antenna. Will damage the performance of the system.
Therefore, the energy reflected back by the metal creates an interference between the RFID Label and the RFID UHF reader. Therefore, the application of RFID technology in an environment with a large amount of metal materials will make the actual RFID read/write rate and read/write distance, as well as the reliability greatly reduced.
In recent years, with the rapid development of passive RFID technology, embedded RFID electronic tags have been in the production stage, or half of the RFID function, depreciation makes it different from other similar products in the market competitiveness.
