RF (Radio Frequency) technology and RFID (Radio Frequency Identification) technology work similarly, in that they use radio waves to transmit information wirelessly.
In RF technology, a device transmits a radio signal at a certain frequency, which can be picked up by a receiver tuned to that frequency. This technology is used in many applications, including broadcasting, wireless communication, and remote controls. In the case of RF protection devices, they emit signals that can detect and locate other RF signals that may be used for spying, tracking, or other unauthorized purposes.
RFID technology works by using small RFID tags or chips that contain a tiny antenna and a microchip. When an RFID reader sends out a radio signal, it energizes the antenna on the tag, which sends back a signal containing its unique identification code. This technology is used in many applications, including inventory tracking, payment systems, and access control. In the case of RFID blocking devices, they work by preventing RFID signals from being read or transmitted, thus protecting sensitive information from being stolen.
