The technology RFID (Radio-frequency identification) has to be a part of everyday life of people in that technology. Many people may have borrowed books from the library. Used to pass into dormitories. Offices or buildings. Will find that the check only a small piece of the device. Go near the only I can check. Or identification has already This technology, called RFID.
Examples of RFID Tags affixed to the back label.
RFID system is used to store information or provide information. Function similar to the Smart Card or Barcode, but perform better. Because in Smart Card, it must be direct contact between the collected information to readers of Barcode itself must be facing the reader data as well, but in the RFID system that the card can stay away from the reader without contact. the reader in any way due to the transmission of RFID system that uses radio frequency (RFID stands for "Radio Frequency IDentification") as a medium for the transmission. There will be an IC microchip mounted on a small card, tag or label, in which micro-chip will be required to provide information. And the frequency output by the computer to read RFID.
Elements of the RFID system has two parts together.
- RFID Tags, or identification plate. Is used to send signals to provide information to the receiver consists of a small circuit board and a small antenna, a small dipole. Embedded in a card or tag that identifies the data
- Signal the reader (RFID Reader) is taken as the signal from the RFID Tags have both installed and portable with. Consists of transmit and receive radio signals. The control and antenna. Frequency is equal to a frequency of RFID Tags on the signal response by interacting with RFID Tags will be sent back signals. Signals are converted to digital data and sent to processing.
