Frequently
Asked Questions
The following is a list of commonly asked questions on Radio
Frequency Identification (RFID). We at RFIDCAM are here to help
with any questions on RFID and/or PDC products. Don't hesitate
to contact us.
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.
