RFID technology consists of two segments such as a reader and a label or tag. These labels or tags are included with a receiver and a transmitter. There are two segments of the RFID tags such as a microchip for storing and processing the information and an antenna for getting and transmitting a signal. The tag involves a particular serial number for a particular object.
A two-way radio transmitter which is known as reader or interrogator sends the signal to the tag by using an antenna. You may search for the RFID chip timing Rancho Cucamonga California for obtaining more information on this regard.
