What does the acronym RFID stand for?
What is it used for? (6 marks)
1) The acronym RFID stands
for radio frequency identification device. Radio Frequency
Identification is ranked among the top 10 of dominant future technologies
2&3) It is used for Ubiquitous computing which is advanced
computing concept where computing is made to appear everywhere and anywhere.
Ubiquitous computing can be used in any device. It can be used anywhere and
everywhere.
4) RFID works by digital data encoded in RFID tags or smart
labels are captured by a reader via radio waves. RFID is similar to bar-coding
in that data from a tag or label are captured by a device that stores the data
in a database. Data
collected from tags is then passed through communication interfaces (cab be
cable or wireless) to host computer systems in the same manner that data
scanned from bar code labels is captured and passed to computer systems for
interpretation, storage, and action.
5) RFID tags come in a wide variety
of shapes and sizes:
Animal tracking tags, inserted beneath
the skin, can be rice-sized. Or a cat flap. This works by a chip being on the
cat’s collar and the cat flap only lets the cat through with this chip. It
doesn’t let any other cats through. A car manufacturer wants to find out more about when and
where the seat it has ordered for your car was assembled. Thanks to RFID, the
company could simply confirm safety information deposited in a database by the
manufacturer of the seat.
6) Credit-card shaped for use in
access applications.
In
the future they could be used for Home.
It could replace keys with cards, automatic I.d related functions,
energy-saving and more personal, tag activating behaviours (e.g. turn lights
on, turn gadgets on or off). Developments
in RFID technology continue to yield larger memory capacities, wider Reading
ranges, and faster processing.
Here are some other ways
they might be used in the future;
- Real-time parking spaces indicators (vehicular services).
- Self-check in at Libraries / rental services (minimizing
labor costs). Self-service tills and points will also advance.
- Building Security - secure access controls, documentation and
passports.
- Airports - for baggage (and maybe traveler) tracking and tracing/locating.
RFID could also be used by Airlines for their own assets, as well as
customers.
- Environmental - Energy, Ozone & Pollution measuring
equipment.
- SMART home controls - systems to manage
home/business energy consumption/production – smart cards could activate energy
sources. Smart Home Controls could advance in to more areas of
consumption.
- Toll/road – collection/charging and control measures. Many more RFID based
payment collection systems.
- Vehicles - Tyre Pressure, Engine and Fuel related & Exhaust monitoring measures
(e.g. carbon footprint measures).
