RFID uses radio waves to automatically identify objects. It consists of a tag attached to the object and a reader that detects and reads the tag. The tag contains an antenna and microchip that stores information. The reader emits radio waves to power the tag and read its data from a distance without contact. Common applications include inventory tracking, transportation payments, and access control like passports. RFID tags come in passive and active types. EPC Gen 2 is the standard protocol that defines the physical and logical specifications for UHF RFID systems, including tag and reader communication methods and message formats.

It is meant for applications where a physical touch, or close to it, is required in order to maintain security. NFC is planned for use in mobile phones for, among other things, payment, in conjunction with an electronic wallet
Radio Frequency identification (RFID) technology has become emerging
technique for tracking and items identification. Depend upon the function; various RFID
technologies could be used. Drawback of passive RFID technology, associated to the range
of reading tags and assurance in difficult environmental condition, puts boundaries on
performance in the real life situation [1]. To improve the range of reading tags and
assurance, we consider implementing active backscattering tag technology. For making
mobiles of multiple radio standards in 4G network; the Software Defined Radio (SDR)
technology is used. Restrictions in Existing RFID technologies and SDR technology, can be
eliminated by the development and implementation of the Software Defined Radio (SDR)
active backscattering tag compatible with the EPC global UHF Class 1 Generation 2 (Gen2)
RFID standard. Such technology can be used for many of applications and services.
My presentation explores how RFID system works and describes briefly about history of RFID, active & passive tags, modes of transmission of data and applications

RFID in Transportation Executive Summary
Pravallika Dubbakula
Wilmington University
Executive Summary
A study has been done on the use of radio frequency Identification and its commercial use in commercial industries. The aim of the study was to understand how the technology can help in providing information to a centralized control unit when the commodity transport vehicle or the items are being transported from one place to another. The study also undertook a detailed examination of the process that is used in the technology and the benefits of the Radio frequency identification technology in commercial industries.
It was found that the use of the technology reduced the losses in transit and made it simpler to use and tag the items for purchase or sale. It also helped to lower mal – practices when vehicles with goods were in transit from region to another. The radio frequency identification technology is the latest available technology in tracking systems using sensors. It has an electromagnetic field which is activated and increases the strength of the sensors when it apses by a reader which has sensors that picks up the data that has been micro chipped into the items or vehicles. These signals are transmitted to a centralized unit where it is transformed into readable information providing the whereabouts of the vehicles and the items.
A tag is attached and this tag is then further attached to the items. It was also found that there are 2 types of RFID tags one is passive and the other is active. The passive tags collect their energy resources from the readers that are installed close by and the active tag have their own power resources built into the tags such as small batteries that are powerful enough to transit information to a reader.
The data about the vehicles or the reader is sent using radio wave transmissions. It has also been found from the study that the radio frequency identification is one of the forms of automatic- Identification and data capture from tags known in short as – A.I.D.C. The most common method of radio frequency identification is implanting it into livestock, individuals and items. The tags have worked per their mechanisms even when they have been embedded into:
The radio frequency identification standards have been laid out in the ISO-IEC – 18000 and the ISO-IEC-29167. The standards specify the details of the methods that can be used for cryptographic encryption and reader authentication. It also includes standards for in the air – privacy concerns of interception. The third standard for the technology is the ISO-IEC-20248 which provides the guidelines for the digital – signature and bar code requirements.
The tags are simply labels, and the readers are two way transmitters for radio wave signals which transmit the signal to the tag and read the response that is sent by the tag. The tags that are mainly used are the active tags since they have their own ...

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2. What is RFID
chip
Antenna
Radio-frequency
identification
(RFID) is the use of a wireless noncontact system that uses radiofrequency electromagnetic fields to
transfer data from a tag attached to an
object, for the purposes of automatic
identification and tracking.
RFID is also called dedicated short
range communication(DSRC)
9. EPC Gen 2 Architecture
Each RFID tag contains a unique code that facilitating
the identification process & is known as EPC
EPC is the new Electronic Product Code that
replaces the older UPC (Universal Product Code)
found on many item labels and is a set of numbers plus
a bar code.
Since UPC first started in 1963 it became out of date
with today's global economies and EPC is
the Radio Frequency Identification (RFID) modern
day equivalent of the older UPC.
10. In most instances, EPCs are encoded on RFID tags
which can be used to track all kinds of objects
including: trade items, fixed assets, documents, or
reusable transport items.
"Class-1" refers to the functionality of the tag while
"Gen-2" refers to the physical and logical standards of
tag and the encompassing system. These standards are
maintained by EPCglobal.
Gen 2, EPC Gen 2, EPC C1G2 are the short names
commonly used instead of "Electronic Product
Code Class 1 Generation 2" standard.
12. Working of RFID
A RFID system is made up of two parts: a tag or label and
a reader.
RFID tags or labels are embedded with a transmitter and
a receiver.
The RFID component on the tags have two parts: a
microchip that stores and processes information, and an
antenna to receive and transmit a signal.
The tag contains the specific serial number for one
specific object.
13. To read the information encoded on a tag, a two-way radio
transmitter-receiver called an interrogator or reader emits a
signal to the tag using an antenna.
The tag responds with the information written in its
memory bank.
The interrogator will then transmit the read results to an
RFID computer program.
16. Types of RFID Tags
There are two types of RFID tags: passive and battery
powered.
A passive RFID tag will use the interrogator’s radio
wave energy to relay its stored information back to the
interrogator.
A batter powered RFID tag is embedded with a small
battery that powers the relay of information.
17. RFID readers
Reader functions:
•Remotely power tags
•Establish a bidirectional data link
•Inventory tags, filter results
•Communicate with networked
server(s)
•Can read 100-300 tags per second
Readers (interrogators) can be at a
fixed point such as
•Entrance/exit
•Point of sale
Readers can also be mobile/hand-held
18. RFID communication
Host manages Reader(s) and issues Commands
• Reader and tag communicate via RF signal
• Carrier signal generated by the reader
• Carrier signal sent out through the antennas
• Carrier signal hits tag(s)
• Tag receives and modifies carrier signal– “sends back” modulated
signal
•Antennas receive the modulated signal and send them to the Reader
•Reader decodes the data
• Results returned to the host application
19. EPC Gen 2 Physical Layer
The physical layer defines how bits are sent between the
RFID reader and tags.
In the U.S., transmissions are sent in the unlicensed 902–
928 MHz ISM band. This band falls in the UHF (Ultra High
Frequency) range, so the tags are referred to as UHF RFID
tags.
The reader and tags use forms of ASK (Amplitude Shift
Keying) modulation
They take turns to send bits, so the link is half duplex.
20. There are two main differences from other physical
layers.
The first is that the reader is always transmitting a
signal, regardless of whether it is the reader or tag that is
communicating.
Naturally, the reader transmits a signal to send bits to
tags. For the tags to send bits to the reader, the reader
transmits a fixed carrier signal that carries no bits.
The tags harvest this signal to get the power they need
to run; otherwise, a tag would not be able to transmit in
the first place.
21. To send data, a tag changes whether it is reflecting
the signal from the reader, like a radar signal bouncing
off a target, or absorbing it.
This method is called backscatter.
It differs from all the other wireless situations
Backscatter is a low-energy way for the tag to create
a weak signal of its own that shows up at the reader.
For the reader to decode the incoming signal, it must
filter out the outgoing signal that it is transmitting.
22. The second difference is that very simple forms of
modulation are used so that they can be implemented on a
tag that runs on very little power and costs only a
few cents to make.
To send data to the tags, the reader uses two amplitude
levels.
Bits are determined to be either a 0 or a 1, depending on
how long the reader waits before a low-power period.
The tag measures the time between low-power
periods and compares this time to a reference measured
during a preamble.
24. Tag responses consist of the tag alternating
its backscatter state at fixed intervals to create
a series of pulses in the signal.
Anywhere from one to eight pulse periods
can be used to encode each 0 or 1, depending
on the need for reliability.
26. EPC Gen 2 Tag Identification Layer
•To inventory the nearby tags, the reader needs to
receive a message from each tag that gives the
identifier for the tag.
•The reader might broadcast a query to ask all tags
to send their identifiers.
27. The closest protocol for the current situation,
in which the tags cannot hear each others’
transmissions, is slotted ALOHA, one of the
earliest protocols.
This protocol is adapted for use in Gen 2 RFID
In the first slot (slot 0), the reader sends a
Query message to start the process.
Each QRepeat message advances to the next
slot. EPC Gen 2 Tag Identification Layer
29. Tags do not send their identifiers when they first
reply.
Instead, a tag sends a short 16-bit random number
in an RN16 message.
If there is no collision, the reader receives this
message and sends an ACK message of its own.
At this stage, the tag has acquired the slot and sends
its EPC identifier.
30. The reason for this exchange is that EPC identifiers are
long, so collisions on these messages would be
expensive.
Instead, a short exchange is used to test whether the
tag can safely use the slot to send its identifier.
Once its identifier has been successfully transmitted,
the tag temporarily stops responding to new Query
messages so that all the remaining tags can be identified
31. If the reader sees too many slots with no responses or too
many slots with collisions, it can send a Qadjust message to
decrease or increase the range of slots over which the tags
are responding.
The reader can also write data to tags as they are
identified.
32. Tag Identification Message Formats
The message is compact because the downlink rates are limited,
from 27 kbps up to 128 kbps.
33. The next flags, DR, M, and TR, determine the physical
layer parameters for reader transmissions and tag
responses.
Then come three fields, Sel, Session, and Target, that
select the tags to respond.
In this way, multiple readers can operate in overlapping
coverage areas by using different sessions.
34. Next is the most important parameter for this command, Q.
This field defines the range of slots over which tags will
respond, from 0 to 2Q−1. Finally, there is a CRC to protect the
message fields.
the Query message is much shorter than most packets too.
The tag responses simply carry data, such as the EPC identifier.
Originally the tags were just for identification purposes
35. Advantages of RFID:
Inventory efficiency
Vulnerability to damage minimized
Easy to use
High memory capacity
Disadvantages of RFID:
Security concerns
High cost
Unread tags
