Zigbee Based Indoor Campus Inventory Tracking Using Rfid ModuleIJERA Editor
This is a very useful application of RFID (Radio-frequency identification) and is very commonly used in institutes, offices, homes and so on. An RFID system consists of a reader device and a transponder. A transponder or tag has a unique serial number which is identified by the reader. Here RFID has been interfaced with ARM Processor to provide secured access. The relevant messages are also displayed on a 16x2 LCD.RFID automated access for door controls to buildings, departments, rooms, secured closets (wiring, PBX, etc.) and cabinets is very cost effective and secure to use. Many people do not realize how easy it is to implement card access systems such as card access door or doors using RFID readers and RFID Cards or Key fobs for Secured Access Control Management. You can even use smart readers for computer rooms and securing individual computers. RFID tags are categorized as either active or passive. Active tags are powered by an internal battery and are typically read/write,i.e tag data can be rewritten or modified. Passive tags operate without a separate external power source and obtain operating power generated from the reader.
RFID and its implementations in different fields like logistics, animal keeping. Details regarding how it works and what the various components of rfid.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. RFID
Introduction :
RFID – Radio Frequency Identification is An ADC
(Automated data collection).
It is a wireless non-contact radio system to transfer data
from a tag attached to an object.
RFID is a new generation of auto identification and data
collection technology which helps to automate business
processes and allows identification of large number of
tagged objects like books using radio waves.
RFID tag wirelessly sends bits of data, when it is
triggered by a reader.
3. A SAMPLE RFID TAG
A paper label
with RFID inside
an antenna,
printed, etched
or stamped ...
… and a chip
attached to it
… on a substrate
e.g. a plastic
foil ...
4. HISTORY OF RFID
The concept of RFID is based on the barcode.
First barcode patents was in 1930s.
RFID technology was first used in world
war- II for identification, friend or foe (IFF)
systems, and has been available in one form
or another since 1970’s.
Mario cardullo’s device (1973) was first true
ancestor of modern RFID.
5.
The first patent to be associated with the
abbreviation RFID was granted to Charles
Walton(1983).
RFID is being used to tie the physical world
with the virtual world. RFID in social media
first came to light in 2010 with Facebook's
annual conference.
6. RFID technology uses radio waves as the medium to
transfer the data from an electronic tag, called RFID
tag, through a reader for the purpose of identifying and
tracking the object.
RFID technology uses
I) RFID tag.
II) RFID reader.
III) Antenna.
IV) Middle ware.
V) Host computer.
8. Many types of RFID exists, but at the highest level based
on the type of tag and the power sources and their
powered infrastructure, we can divide RFID devices into
two classes:
1). Active RFID.
2). Passive RFID.
9. An active rfid tag talks first, it beacons.
This tag does not depends on a reader to be
energized.
Active tag can be read at much greater ranges and
is equipped with a battery that can be used as a
partial or complete source of power .
Active tag transmits radio signals.
It has capability to perform independent
monitoring control.
Active rfid tags may even be equipped with
autonomous networking; the tags autonomously
determine the best communication path.
10. Active rfid tag
Reader

Battery
Listens for
beacons
Communicates with
RF and it beacons
Stores and
evaluates the
data.
11. Passive tag uses reader talk first.
Tags are muted until a signal is received from
reader.
Passive RFID tag functions without any battery;
these tags have a useful life of twenty years or
more.
The tag is much less expensive to manufacture and
is smaller in size.
Passive RFID tag costs upto $0.25 to $10.
Power and data transmission occurs between
reader via antenna.

14. A RFID reader transmits an encoded radio
signal to interrogate the tag.
RFID readers are two-way radio transmitterreceiver called interrogates or reader.
The reader sends a signal to the tag and read
its response.
The readers generally transmit their
observations to a computer system running
RFID software or RFID middleware.
15. Signaling between the reader and the tag is done in
several different incompatible ways, depending on the
frequent band used by the tag.
This signaling is of two types
1). Near-field.
2). Far- field.
16. Near field RFID is based on the principle of faraday’s
magnetic induction.
A reader passes a large alternating current through a
reading coil, resulting in an alternating current
through reading coil.
If you place a tag that incorporates a smaller coil in
this field, an alternating voltage will appear across it.
The current is proportional to the load applied to the
tag’s coil. This concept is load modulation.
18. RFID tags based on far-field emissions capture
electromagnetic waves propagating from a dipole
antenna attached to reader.
Unlike induction designs, information can’t be
transmitted back to the reader using load
modulation.
By changing the antenna’s impedance
overtime, the tag can reflect back more or less of
incoming signal in a pattern that encodes the tag’s
ID.
20. Host controller is a computer that communicates with the
reader, it performs two main functions.
1). It is receiving data from the readers and performing
data processing such as filtering and collation .
2). It serves as a device monitor, making sure the reader
is functioning properly, securely and with up to date
instructions.
Host controllers are connected to readers through
network technologies such as TCP/IP or sometimes
through serial connectivity.

22. We proposed a rfid based employee tracking system
with the functionalities as
1). It tracks the employee location with in the campus.
2). It stores the data of an employee during his stay in
the region.
3). Graphical interface system.
4). Automatized attendance system can be embedded.
