1.1 PURPOSE

Radio frequency identification (RFID) is a generic term that is used to describe a

system that transmits the identity (in the form of a unique serial number) of an

object or person wirelessly, using radio waves. It's grouped under the broad

category of automatic identification technologies.

Radio Frequency Identification (RFID) and wireless RF sensors are the conduit

between the physical world and the digital world because it allows physical

objects to be identified and differentiated by computers. These technologies

provide the ability to identify, locate, and sometimes sense the conditions of

animate and inanimate entities and their surrounding environment, and enable

real-time decisions to be made based on that information.

RFID is the reading of physical tags on single products, cases, pallets, or re-usable

containers that emit radio signals to be picked up by reader devices. These devices

and software must be supported by a sophisticated software architecture that

enables the collection and distribution of location-based information in near real

time. The complete RFID picture combines the technology of the tags and readers

with access to global standardized databases, ensuring real time access to up-to-

date information about relevant products at any point in the supply chain. A key

component to this RFID vision is the EPC Global Network.

The purpose of an RFID system is to enable data to be transmitted by a portable

device, called a tag, which is read by an RFID reader and processed according to

the needs of a particular application. The data transmitted by the tag may provide

identification or location information, or specifics about the product tagged, such

as price, color, date of purchase, etc. RFID technology has been used by

thousands of companies for a decade or more. . RFID quickly gained attention

because of its ability to track moving objects. As the technology is refined, more

pervasive - and invasive - uses for RFID tags are in the works.

1.2 SCOPE OF RFID

Stellar 2011 Page 3


RFID has many applications

It is used in enterprise supply chain management to improve the efficiency

of inventory tracking and management.

RFID tags are carried by people to allow them to gain access to facilities

or services in areas like:

For secure access to work place. Access to a computer or vehicle. Access to travel on trains/buses.

The Healthcare industry has used RFID to create tremendous productivity

increases by eliminating "parasitic" roles that don't add value to an

organization such as counting, looking for things, or auditing items.

Logistics and transportation are major areas of implementation for RFID

technology. Yard management, shipping and freight and distribution

centers use RFID tracking technology.

Many financial institutions use RFID to track key assets and automate

Sarbanes Oxley SOX compliance.

RFID can provide race start and end timings for individuals in large races where it is impossible to get accurate stopwatch readings for every entrant.

In the race, the racers wear tags that are read by antennae placed alongside the track or on mats across the track. UHF tags provide accurate readings with specially designed antennas.

Barcode needs human interaction for proper operation. It requires time-of-

sight access to an optical scanner for the product related information. The

barcode is to be replaced if the information it contains needs modification,

but in RFID it can be modified at stages of the supply chain by the

interaction between the microchip and the reader software. The barcode

system is less accurate as compared to RFID.

Libraries have used RFID to replace the barcodes on library items. The tag

can contain identifying information or may just be a key into a database.

1.3 DEFINITIONS, ACRONYMS, AND ABBREVIATIONS

RFID(Radio Frequency Identification): It is a superior and more efficient

way of identifying objects than manual system.

HTML (Hyper Text Markup Language): It is used to create static web

pages.

WASCE (WebSphere Application Server Community Edition): It is an

application server that runs and supports the J2EE and the web service

applications.

DB2 (IBM Database 2): It is a database management system that provides a

flexible and efficient database platform to raise a strong "on demand"

business applications.

HTTP (Hyper Text Transfer Protocol): It is a transaction oriented client/

server protocol between a web browser and a web server.

XML (Extensible Markup Language): It is a markup language that was

designed to transport and store data.

UML(Unified Modeling Language): It is a standard language for writing

software blueprints. The UML may be used to visualize, specify, construct

and document.

RAD(Rational Application Developer): It is a development tool that helps

to design web pages and also helps to design the diagrams like ER,

Database schema diagrams and to generate DDL.

1.6 OVERVIEW

The SRS will include two sections, namely:

Overall Description: This section will describe major components of the

system, interconnections, and external interfaces.

Specific Requirements: This section will describe the functions of actors,

their roles in the system and the constraints faced by the system.

2. OVERALL DESCRIPTION

2.1 PRODUCT PERSPECTIVE

An attendance recording system’s basic function is to keep a record of the time at

which the employees of a particular firm report to work and leave from work. It is

one of the most widely used event recording application in the industry today. A

track of employee attendance is a must for payroll generation. The traditional

method of maintaining an attendance register makes the job very tedious and

prone to human errors. The collection and processing of data of employee.

Attendance which may include leaves, half working days, overtime etc. and using

it to generate the payroll manually consumes important man hours, which in turn

could be used to increase productivity and in turn profitably of the firm. In case of

an error, even more time will be used to detect and rectify it, if the process is

manual. The whole process will be simplified to great extent.

If a system is available by means of which attendance data be stored, accessed,

sorted, and processed and obtained in a form of a detailed report which may be

Stellar 2011 Page 6


used directly for payroll generation, hence saving a lot of precious time. It

functions as a network of microchip “smart tags” and receivers. Each smart tag is

embedded with a unique electronic product code (EPC) and a micro-antenna.

Once assigned, the EPC becomes a DNA-like marker for the item, identifying it

from every other item in the world. When a tagged item passes within range of a

reader, the reader retrieves the EPC via radio waves, identifies the item and its

exact location, and relays this real-time information to a central computer.
