This document discusses RFID and the Internet of Things (IoT). It describes RFID as an automatic identification technology that uses radio waves to identify objects. The IoT allows physical objects to be connected to the internet and be remotely monitored and controlled. The architecture of an IoT system generally has three layers - a perception layer to collect data from sensors and RFID tags, a network layer to transmit the information, and a service layer to process and analyze the data. RFID has applications in various fields including healthcare, transportation, and access control. Challenges to the wider adoption of RFID include collision problems, security issues, and high tag costs.
4. INTRODUCTION
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.

6. 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.

7. The Internet of Things allows people and things to be
CONNECTED

8. ARCHITECTURE OF IOT.
The IOT system architecture is generally divided into three
layers.
PERCEPTION LAYER
NETWORK LAYER
SERVICE LAYER
8
9. PERCEPTION LAYER
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.
9
10. NETWORK LAYER
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
11. 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.
11
13. RFID TAGS
The essential components of rid tags are
ANTENNA.
INTEGRATED CIRCUIT.
PRINTED CIRCUIT BOARD.
13
14. COMPONTENTS FUNCTIONS.
The function of antenna is to transmit and receive
radio waves for communication.
The IC is a packaged collection of components
that provide brain for the tag.
The PCB is the material that holds the circuit
together.
14
15. RFID READER
The reader is for the communication with any
tags in its read range.
Two functional blocks
High frequency interface.
Control system.
15
16. APPLICATION SYSTEM
Also called data processing system.
Initiates all readers ad tag activities.
Can be an application or database.
16
17. THE RFID CAN BE USED IN THE FOLLOWING FIELDS.
Health Care and Medicine.
Military and Defense.
Transportation.
Banking
Access control 17
18. 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
19. Payment by mobile phones.
Credit card companies developed specialized micro SD
cards containing both RFID tag and a reader.
After inserting the microSD, a user's phone can be linked
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 read
at a distance. 19
20. LATEST INFORMATION
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.
20
21. CHALLENGES OF RFID TECHNOLOGY
Collision Problems.
Security problems.
The cost of the RFID tags are still expensive.
21
22. CONCLUSION
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.
