How can you interupt a frequency
WebThe frequencies used for RFID systems are typically in the range of 125 kHz to 13.56 MHz. To block RFID chips, a device that emits a signal at the same frequency as the RFID system can be used. However, it is important to note that the use of such devices may not be legal in all situations. Can RFID be intercepted? WebReady to find your Frequency?
