RFID low frequency from 125Khz to 134.2KHz introduction
RFID Low frequency (from 125KHz to 134KHz) In fact, RFID technology has first been widely used and promoted at low frequencies. The frequency is mainly through inductive coupling To perform work, that is, there is a transformer coupling between the reader coil and the inductor coil. Through the alternating field of the reader The voltage induced in the antenna of the inductor is rectified and can be used as a power supply voltage. The magnetic field area can be well defined, but The [...]
