1. What is RFID?
Radio Frequency Identification.
2. How does RFID work?
RFID technology provides a wireless, over-the-air interface. Unlike bar code data storage, line-of-sight communication is not necessary.
RFID uses an integrated microchip and antenna that reads information. The combination of the chip and antenna is called an RFID transponder, tag or inlet. When the RFID transponder is placed in the field of an RFID reader, information is transmitted to the reader and processed by a computer.
3. What is Smart Band?
Smart Band consists of an RFID microchip (with a unique factory imbedded serial number) and antenna inlet sealed inside a non-transferable and secure wristband.
4. Where is RFID currently being used?
Originally adapted during World War II to identify "friendly" aircraft, RFID has proliferated into other applications such as toll payment, supply chain management, cashless payment, ticketing, brand authentication, security access, patron identification and amusement parks.
5. Can RFID be used
as a tracking device?
Since passive RFID transponders must be closely
coupled with a reader to transmit information, their
read distance is generally limited to three feet
maximum. Active transponders use a battery to power
the chip's circuitry and broadcast a signal to a
reader. Transmission distances range from 100 feet
or more. However, factors including the operating
frequency, antenna size, reader power and proximity
to metal can affect the overall read distance.
6. Are there any health risks associated with
RFID and radio waves?
RFID utilizes the low-end of the electromagnetic
spectrum. The waves emitted from readers are no
more dangerous than radio waves signaled to your
car stereo.
