RFID tag can store information. A reader is there for reading the information that is encoded in the tag. By using an antenna, a signal is emitted by the reader to the tag. Information is written in the memory bank of the tag. Then the data is transmitted by the interrogator to an RFID computer application. Two kinds of RFID tags are there such as battery powered and passive.
A passive tag uses radio wave energy for transmitting the stored information to the interrogator. In order to get more information on this regard, it is suggested to search for the RFID chip timing Cape Coral Florida on the Internet.
