Vehicle Tracking & Ticketing System Using RFID

1

MANUAL TICKETING• Frequency of getting errors and mismatch in entries was a serious problem

USING BARCODES• Major problem of line-of-sight operation• Less expensive but less secure

BIOMETRIC DEVICES• High cost of implementation• Dependent on physiological characteristics that is not fixed

SMART LABELS• Less secure compared to RFID technique


2

Radio-frequency identification (RFID) is an automatic identification

method, relying on storing and remotely retrieving data using devices

called RFID tags or transponders.

Technology that incorporates the use of electromagnetic or

electrostatic coupling in the radio frequency(RF) portion of the

electromagnetic spectrum to uniquely identify an object, animal or person.

An alternative to bar code

Contactless Smart Cards

The primary benefits of RFID technology over standard bar-coding are:

• Information stored on the tag can be updated on demand

• Huge data storage capacity

• Small surface area requirement

• Instantaneous data identification

• Data collection from multiple items

• Longer read range : line-of-sight not required

• Greater resistance to scratches and physical abuse

• Greater accuracy in data retrieval and reduced error rate

Tags will be embedded into the vehicle.

Reader will send electromagnetic waves to the tag.

Power will be drawn by the tag from these waves

Tag will return back vehicle information

Stored in READER memory

Reader will demodulate & convert into digital data


6

Tags will be attached to students ID card

Antenna will sense the tag

Information will be fed into the reader

Reader will decode these data

Information will be send to the host system by reader.

Agile Reader • One that can read tags operating at different frequencies.

Dumb reader• One that read only one type of tag i.e. of same frequency.• Has very little computing power

Intelligent reader• Run on different protocols• Can filter data• Can run application

TYPES OF RFID READER


10


• Most simple

• Do not require integrated power source

• Most inexpensive tag

When RFID tag is within the interrogation zone of the reader i.e. Interrogator equipment, sufficient power is extracted from the interrogator to power up the tag or circuit, or special reflective material.

It then transmitting data back to the interrogator. This is known as

Passive RFID.

11


Uses battery to run chip circuitry

and communicates by drawing power

from the reader.

• More complex

• Requires integrated power supply

• Higher cost

12

These RFID incorporate a battery to

increase range (typically by a factor of

3 over passive) for collecting data, tag-

to tag communication etc.


• Most complex

• Requires integrated power supply

• Higher cost

13

Tag antenna

• Conductive element that enables the tag to send or receive data

Reader antenna

• Transfers information to and fro from tag antenna

14

Low frequency (125-134KHz)

• Used for shorter read range

High frequency (13.56MHz)

• Used for longer read range

Ultra high frequency (866-915MHz)

• Used for greater read distance but more sensitive

to environment factor

Microwave frequency(2.45-5.8GHz)

The resource requirement can be parted into three sections: RFID SECTION (main focus on the tools required for tracking the various tags used)

RFID tag enabled ID card• The tag will carry the information about the client and will form the basic input of the system

RFID writer• It will write the details about the client onto the tag

RFID reader• It will read the details about the client from the tag


18

COMPUTER SECTION(Deals with the systems required for the implementation of the VTTS)

Computer terminal• An electronic hardware device that enables a computer to receive or deliver data

LAN connectivity•Local area network

Computer server•It is a computer system used for maintaining the data base


19

SOFTWARES AND DEVELOPMENT TOOLS(Deals with design tools for the purpose of design and implementation)

Front-end tools• Provides interactive interface to the user• Allows data to be entered into a server

Back-end tools• Provides network that have been requested by client

Crystal reports• Helps users to create flexible, high fidelity reports


20

Point of sale • operate as a part of toll road application

-Electronic toll collecting system-Parking garage access

Close loop• operate under the control of single owner

-Medium scale organization-Retail industry sectors

Open loop• operate under the control of multiple owner.


21


Non contact, non line-of-sight nature of technology

Tag can be read from variety of substances

Faster read rates

Multiple tags can be read in single pass across the reader

Paper less tracking of equipment and personnel

High degree of scalability

22

Speed of transaction

Increased safety

Cost reduction

Fewer queues

More reliable equipment

Reduces fraud

Faster processing of passengers

Intellicon - pilot project for BEL Bangalore, tags installed on employee buses. Buses inside the BEL campus were tracked with the aim of gauging employee punctuality.

Patni Computer Systems Lab – Implemented Animal Tracking System.

Wipro Technologies - Member of the Electronic Product Code (EPC) - Setting up a lab to study RFID - Working on pilot projects

Infosys Technologies – RFID consulting on logistics player in the RFID space.

TCS have tied up with Hyderabad university to produce RFID tagged mark sheets & degrees to deter use of fake degree.
