RFID Overview
• RFID stands for Radio Frequency Identification.
• It is an AIDC (Automatic Identification and Data
Capture) technology that uses Radio Frequency
Waves to transfer data between a Reader and a
movable item to identify, categorize or track.
• Fast and does not required physical contact between
reader and tag.
• Performs the operations using low cost components.
• Attempts to provide unique identification and
backend integration that allows for wide range of
application.

RFID Overview
• RFID is one of the most exciting technology that
emphasize the working practice by increasing
efficiency and improving profitability.
• RFID have the potential to provide remote monitoring
capabilities, which can help in industrial control,
environment monitoring and defense.
• Most probably the best, cheapest and accurate
technology as a replacement of today’s barcode with
vast possibilities, such as individual serial numbers for
each item and the possibility to read these serial
numbers at a distance of several meters.

Components of RFID & their
Technical Aspects
• A basic RFID system consists of three main
components
1. An Antenna or Coil
2. A Transceiver with
decoder
– Fixed Point
– Mobile or Handheld
3. A Transponder (RF tag)
– Active Tag
– Passive Tag https://www.epc-rfid.info/rfid

Liverpool Hospital - Sydney
• 23 Operating Theaters.
• 877 Bed Capacity.
• Pathology including 12000
units of red cell for transfusion
each year.
Case study – RFID in Medical
https://www.blood.gov.au/liverpool-hospital-rfid-case-study

Problem
• No Design flow for Blood
Transfer through fridge.
• Improper arrangement of
blood samples &
inaccuracy in handling
patient blood data.
• Danger of unauthorized
access.
Solution
• Addition of RFID tag to
each unit with patient
details; secure access.
• Units are scanned through
organized software
keeping entry of each unit
when added or removed
from fridge.
• For incorrect blood
samples chosen, audible
alarm with visual message
is activated.

Conclusion
• Confidence gain within medical
staff.
• No unauthorized excursions.
• Accurate handling of Patient
Data.

Confectionery Manufacturer
• Production of Sweets.
• Tracking of Semi-finished and
Finished goods is necessary in
this type of Production Process.

Case study – RFID in Manufacturing

Problem
• Direct line of Sight.
• Inaccurate scanning
Procedure.
• Risk of Human Error has
been reported due to
incorrect scanning
transactions.
Solution
• Record Data when a
batch is placed or
removed from process
without manual
intervention.
• Data can be send directly
to control unit without
error and specific
procedure can be
followed.

Conclusion
• No error in entry because
scanning is done automatically
and data is send directly to
control unit periodically.
• Set procedure of registering
entries is established
eliminating scheduling error.
• Error correction can be done at
early and multiple stages.

Construction Material Mgmt.
• Test Case is water supply
project in South Africa.
• 2% savings in material cost,
increases profit by 14.6%.
• The lack of productive material
management has resulted in
18% work hour overruns.

Case study – RFID in Construction
Material Management

Problem
• Large amount of material
involves inaccuracy in
tracking.
• Approach is passive
rather than pro-active.
• Complex and dynamic
process of material
planning, ordering, site
monitoring and lack of
information flow.
Solution
• RFID-CMM can tackle
information flow among
designers, material
planning team,
procurement and
monitoring staff with active
data collection.
• Scanning can be done at
multiple workstations
and multiple stages.

Conclusion
• Effectiveness- $26,400 saved
within 28 weeks of implementation.
• Usefulness- 89% of team members
agreed to productivity of RFID use.
• Fitness- 63 features were assed
• Usability- 82% of participants
agreed, RFID can be used with
little instructions.

For People with Visual and Hearing Impairments
• This research is focused on utilization of RFID for
human beings.
• This Technology will help people with sensory
impairments such as hearing(deafness) and
vision(blindness).
• The people with such impairments faces much
difficulties in regular environment. Currently, they use
white conventional stick for navigation.

RFID
Problem
1. Stick does not help to find the appropriate bus and
board them easily.
2. Navigate across traffic signals

• This device is more reliable than
conventional cane stick in terms of
engineering and use of this
technology can be implemented in a
cost-effective way.
• Increases confidence of people.

Future Vision
• The world will experience a difference once RFID are
implemented into unforeseen topics such as Human
Body.
• Once the current limitations like lack of Global
Standard, security and privacy concerns, cost factors
are addressed, they will reform our life than today.
• RFID can bring revolutionary change in the way we
