Background of RFID
Slide 4
1. Background of RFID (1/4) Mirror-Sunlight- Reflection theory
Basic concept behind RFID is same as Mirror-Sunlight- Reflection
theory Invented in 1948 by Harry Stockman World War II Initial
application was during World War II-The United Kingdom used RFID
devices to distinguish returning English airplanes from inbound
German ones Commercial Operation begun from 1960s
Slide 5
1. Background of RFID (2/4) 5 Radio-Frequency Identification
RFID = Radio-Frequency Identification Briefly the RF stand for
radio-frequency and ID means identifier that allows an item to be
identified, accessed, stored, reprogrammed and communicated by
using radio waves small chip and an antenna The acronym refers to
small electronic devices that consist of a small chip and an
antenna. The chip typically is capable of carrying 2,000 bytes of
data or less.

6 Manufacturing and Processing Supply chain management Security
Controlling access to building Payment systems Location Tracking
Retail 1. Background of RFID (3/4)
Slide 7
RFID advantages over bar-codes 7 No line of sight required for
reading Multiple items can be read with a single scan Each tag can
carry a lot of data (read/write) Individual items identified and
not just the category Passive tags have a virtually unlimited
lifetime Active tags can be read from great distances Can be
combined with barcode technology 1. Background of RFID (4/4)
Slide 8
Concept of RFID
Slide 9
Basic Components of RFID RFID Tags (or Transponders) (or
Interrogator)
Slide 10
RFID Architecture 10 Tags Reader Gateway Database Application
User Interface Backend Fig.1. A General Overview of RFID
Architecture Scanned 2. Concept of RFID (1/7) Firstly items-tag are
scanned by reader; Secondly in backend transmitted data coming
through antenna (RF-wave) are being recognized by RFID-based system
PC. It acts as a middleware communication gateway among items,
reader and system database; Finally it filters out and store data
in RFID- databases for checking the data fault and relevant
operation.
Slide 11
Key component - tag 11 1. Chips: Hold information about
physical object. 2. Concept of RFID (2/7) 2. Antenna: Transmit
radio signal 3. Package: Encases the Chips and Antenna, so that can
be attached to the physical object.
Slide 12
Are All Tags The Same? Three Basic Types: Active Battery
powered memory, radio & circuitry Long Read Range (300 feet)
Active Backscatter (Semi-active) Reader activates tag, but battery
powers memory and circuitry Medium Read Range (10 - 50 feet)
Passive Backscatter Reader powered Shorter Read Range (4 inches -
18 feet) 2. Concept of RFID (3/7)
Slide 13
RFID Tag Operational Frequencies 2. Concept of RFID (4/7) RFID
Tag Operational Frequencies Band Frequency LF 30 300 kHz HF 3 30MHz
UHF 300MHz 3GHz Microwave 2 30GHz Typical RFID frequencies 125
134kHz13.56MHz865 956MHz2.45GHz Read range
3. Disadvantages of RFID (5/8) 24 1. High cost Hard to
implement in low cost products The benefits of RFID > additional
cost
Slide 25
3. Disadvantages of RFID (6/8) 25 2. Materials Problems
Problems with some materials Problems with some materials (Metals
and liquids ) unreadable reflect the radio waves unreadable
Slide 26
3. Disadvantages of RFID (7/8) 26 3. Interference problem has
been occurred interfere with RFID radio waves The presence of
mobile phone towers has been found to interfere with RFID radio
waves
Slide 27
3. Disadvantages of RFID (8/8) 27 4. The risk of using RFID
technology Do not need to have direct contact Do not need to have
direct contact privacy Consumers are apprehensive about their
privacy Others can be tracked the personal information by the RFID
reader
