WHAT IS RFID?

RFID is an automatic technology.

It identify and collect object data through RF.

Signals..

First appeared in 1945

RFID system consists of TAGS and READERS.

RFID DEVICES IN DIFFERENT FORMS.

4

WHAT IS INTERNET OF THINGS?

The IOT refers to uniquely identifiable objects ad

their virtual representation in an internet.

Radio-frequency identification is often seen as a

prerequisite for the Internet of Things.

5

The Internet of Things allows people and things to be

CONNECTED

7

The IOT system architecture is generally divided into three

layers.

PERCEPTION LAYER

NETWORK LAYER

SERVICE LAYER

8

It is the information origin and the core layer of

IOT.

All kinds of information in physical world used in

IOT are collected in this layer by sensors and

RFID tags.

In this layer the information from perception

layer is transported to the next layer.

The layer provides an efficient and

trusted network platform for upper level.

10

SERVICE LAYER

Data management sub-layer.

The data management sub layer processes

complex data.

Application service sub-layer.

The application service sub layer transforms

information and provides good user

interface.

RFID SYSYTEM

Composed of three main components.

RFID TAGS.

READER.

APPLICATION SYSYTEM.

12

RFID TAGS

The essential components of rid tags are

ANTENNA.

INTEGRATED CIRCUIT.

PRINTED CIRCUIT BOARD.

12

The function of antenna is to transmit andreceive radio waves for communication

The IC is a packaged collection of componentsthat provide brain for the tag.

The PCB is the material that holds the circuittogether.

13

RFID READER

The reader is for the communication with any

tags in its read range.

Two functional blocks

High frequency interface.

Control system.15

APPLICATION SYSTEM

Also called data processing system.

Initiates all readers ad tag activities.

Can be an application or database.

16

THE RFID CAN BE USED IN THE FOLLOWING FIELDS

Health Care and Medicine.

Military and Defense.

Transportation.

Banking

17Access control

APPLICATIONS OF RFID TECHNOLOGY

RFID for Intervehicular Communication.

To monitor traffic and vehicle speed in construction zones

or other areas.

In Libraries.

Libraries have used RFID to replace the barcodes on library

items.

The tag can contain identifying information.

18

Payment by mobile phones.

Credit card companies developed specialized micro SDcards containing both RFID tag and a reader.

After inserting the microSD, a user's phone can belinked to bank accounts and used in mobile payment.

Access management.

RFID tags are widely used in identification badges,replacing earlier magnetic stripe.

Tags can also be placed on vehicles, which can be readat a distance.

From this July, several hospital in Europe started

to use RFID tags to track surgical tools.

RFID tags will prevent the loss of surgical

instruments and improve patient care.

CHALLENGES OF RFID TECHNOLOGY

Collision Problems.

Security problems.

The cost of the RFID tags are still expensive.

IOT and RFID defines the future.

The IOT uses a variety of information sensing

device and information processing

equipment.

They are combining with internet to form an

extensive network to intelligentize the objects.
