How do RFIDs benefit in my Life
of Sports?

What is a RFID?

What does an RFID do?

How could these radio frequencies
produce more accurate stats in
sporting events like triathlon and car
or motorcycle races?


A Radio frequency
identification (RFID)
technology uses
wireless radio
communications to
uniquely identify objects
or people.

At their simplest, RFID
systems use tiny chips,
called "tags," to contain
and transmit some piece
of identifying
information to an RFID
reader, a device that in
turn can interface with

Rfids are commonly used
at triathlons to check
how far the runner is
away from the finish line
and also to prevent
cheating and taking
alternate routes.

Why were RFIDs invented?

There are many ways why these radio
frequencies, for more than just
measuring time sporting events.

A RFID is most popular in:

Tracking animals

theft hard plastic tags attached to
merchandise in department stores

Identifying trees and wooden items

History of RFID’s

Radio frequency identification
technology can be traced back
to World War II.

The first invention that was
similar to a RFID tag or chip was
invented in 1946 by Leon
Theremin, which the Soviet Union
used as an espionage tool.

This device was more of a passive
covert listening device, not a
RFID tag or chip.

History Cont.

In 1969, Mario Cardullo invented the first
true ancestor of the current RFID tags or

This device was similar to modern passive RFID
tags, as it had memory and a passive radio

A few years later in 1973 the Los Alamos
Scientific Laboratory created the
technology for the first reflected power
RFID tags.

How it works

This makes a RFID reader
and the tag communicate
between each other
through a radio frequency.

There are three main roles
a RFID reader plays.

A simple RFID
system consists of
a RFID reader and a
RFID tag.

Inside each tag
consists of a radio
transmitter and
radio receiver.

3 Roles a RFID plays


After the incoming signals are slowed
down, RFID then has the responsibility
of decoding the incoming signals into
the words or numbers

A RFID reader has the
responsibility of keeping
RFID tags powered up.


A RFID reader receives
incoming signals from
the RFID tag down.

RFIDs in Sports

RFID football

Jaguar race
Timing Solution



NFL Helmets

RFID Football Helmet which prevents
athletes from falling prey to deadly
heatstroke. The lightweight and shock
resistant transponder attached to it
takes note of body temperature of the
player wearing it.

Jaguar Race Timing

would give better results when
compared to the other timing systems
selling in the market. Handles the best
in harsh weather.


The company has a range of products
which includes sports timekeeping
bikes, shoe and other products. These
solutions are used in sports events
like cycling, cross country running,
marathons and other events as a time
keeping measure.


A RFID can be used in many ways from
timekeeping to tracking devices to
security devices.

Without these we could still live but
they are a great help in society.

RFIDs are useful in today’s world but
as technology increases it will be very
helpful in the future.
