• The term RFID means Radio Frequency Identification

• RFID is emerging as an important technology for revolutionizing a wide range of applications, including supply-chain management, retail sales and healthcare

• Predictions indicate that RFID will be worth billions of dollars in new investments. According to IDTechEx, the RFID market will increase from US$4.96 billion in 2007 to US$26.88billion in 2017

RFID is Radio-frequency identification precisely used for identifying objects

What is RFID?What is RFID?

RFID uses radio-frequency waves to transfer identifying information between tagged objects and readers without line of sight (LOS), providing a means of automatic identification

Components of RFID systems

A typical RFID system consists of: Transponder or Tag Interrogator or Reader A computer network

A tag contains a chip that stores the identifying information of the object or person to which it is attached and an antenna that communicates the information via radio waves.

System Basics: System Basics: The ReadersThe Readers When a tag passes through an RF field that a

reader generates, the tag transmits that information to reader and identify that object or person

Readers (interrogators) can be at a fixed point such as

Application Development Issues (1)Application Development Issues (1)

Devices layerThe devices layer consists of RFID tags and

readers as well as RFID protocolData processing layer

consists of several software components for communicating with RFID readers, filtering and cleaning RFID data

Data integration layerconsists of applications that exploit local RFID data

as well as RFID data coming from outside business entities

Data CharacteristicsData CharacteristicsInaccuracy

Duplicate reads, missed reads, ghost readsLarge-volume streams

Wal-Mart generated Tera bytes of dataTemporality and spatiality

Tagged objects are mobile, different places to moveImplicit inferences

Requires the context of other informationLimited active lifespan

In the active life period the system actively tracks, updates and monitors data

16Abdullah Al Mahmud, 0507006, Dept of CSE, KUET, Bangladesh

Data IntegrationData IntegrationScalabilitySystem should have ability for high volume of data and numerous transactions

HeterogeneityMultiple sites should have functionality to map the company structures among them

ManageabilitySupervision, testing, control, end-to-end processing of RFID data

SecuritySophisticated security measures must be in

ConclusionsConclusions

To precisely identify objects at low cost and without LOS creates many new and exciting opportunities for applications of our daily lives

To develop and deploy these applications, however, researchers must find robust, scalable, secure solutions to the unique challenges of RFID data
