Radio Frequency Identification or RFID is the use of radio waves to identify objects.Unlike the old technique of x-rays used for radiation, MRI is used for creating the exact same images but through radio waves and magnets.An electrical current produced by radio waves is used to heat up a small area of nerve tissue.

n electronics and telecommunications a transmitter or radio transmitter is an electronic device which generates a radio frequency alternating current. When a connected antenna is excited by this alternating current, the antenna emits radio waves.In addition to their use in broadcasting, transmitters are necessary component parts of many electronic devices that communicate by radio, such as cell phones, wireless computer networks, Bluetooth enabled devices, garage door openers
