There are many technologies that can be used to allow business to identify,
assign track and audit. Automating the collection of data about stock, as-
sets, components, and customers reduces costs, increases accuracy and speeds
information
ow. Radio Frequency Identication (RFID) solutions can be
used to help in this.Radio Frequency Identication (RFID) is one of the most
exciting technologies that revolutionize the working practices by increasing
eciencies, and improving protability. RFID is widely recognised as an
important way to provide fast, accurate identication for business solutions.
RFID is a well established technology. It is a versatile technology. It can be
used to tag assets so that information about them can be collected. It can be
used to identify individuals in order to allow or prevent access or to provide
information about their whereabouts. It can be used as part of systems for
logistics and delivery tracking, security or for managing safety inspections.
RFID also can be used as useful technology in Oil's,Mining's extreme envi-
ronments such Identifying Pipe Joints, Oil Tanker Tracking,Automatically
track assets and monitor critical process or movement within the facility.
However, like all technologies, RFID has its strengths and weaknesses.

2.Protocols and Bands.
3.RFID v.s barcode.
4. RFID Design .
5.General Applications, Applications in oil and gas industry.
6. Companies that produce RFID .
7.Problems and concerns.
3. What is RFID?
• Radio Frequency Identification
• A small chip or tag that reads radio waves used for identification purposes
• Does not have to be in line of vision
• Can be attached to implanted in products, animals, or even human beings
4. How does RFID work?
Tags Receives signal from reader and gives a return signal with ID number
Reader sends number to database or server
5.
6. Types of RFID tags
• ACTIVE:
Advantages
Higher storage capacities
Longer read range
Disadvantages
limited by life of battery
high power consumption
8. SEMI- PASSIVE:
battery is used to support the processing unit
Advantages
increase read range
Disadvantages
Larger
More complex
limited by life of battery
9. RFID tag memory
Read-only tags
Tag ID is assigned at the factory during manufacturing
Can never be changed
No additional data can be assigned to the tag
Write once, read many (WORM) tags
Data written once, e.g., during packing or manufacturing
Tag is locked once data is written
Similar to a compact disc or DVD
Read/Write
Tag data can be changed over time
11. RFID readers
Reader functions:
Remotely power tags
Establish a bidirectional data link
Inventory tags, filter results
Communicate with networked server(s)
Can read 100-300 tags per second
16. RFID Antenna Design Process
Select the application and define the requirement
Determine the materials for antenna construction
Determine RF impedance
Identify the type of antenna and its parameters
Perform parametric study and optimization
Build and measure prototypes
Design
requirement met?
Design
Is ready
YesNo
17. Requirements for RFID Antenna
Small enough
Must provide maximum possible signal
Polarization
Be robust
Be cheap
Range
Penetration depth
18. RFID Antenna Patents
More than 50% - US patents every year.
Annual increasing amount is 183.6% from 2001-2005,
The application amount from Jan 2006 to Aug 2006 is
around 88.3% of that in 2005.
21. General application of RFID
Livestock Management
Animal identification, a worldwide market, grows about 30% every year.
22. General application of RFID
Self Service Libraries
Today, over 5,000 libraries worldwide have already introduced RFID, and millions of customers benefit
from the technology.
