NFC - The technology behind the metro cards used in Indian metro trains. Also, this technology has the capability to convert your smartphone into a virtual wallet like Google Wallet.
Near Field Communication is a very Versatile wireless technology. It has its range up to just 10-20 cm, but its short range is its advantage. Lets explore this technology and try to exploit it.
Show different Standards as ECMA 340 and 352. Talks about security problems and solutions. Shows ECMA 385 and 386 as a SSE & SCH services for p2p mode.
As conclusions:
NFC by itself cannot provide protection against eavesdropping or data modification. The solution is the establishment of a secure channel over NFC. Since Man in the Middle attacks are unfeasible, a Diffie- Heffman cryptography can be applied. NFC-SEC standard uses ECDH crypto and AES algorithm.
SENSOR ID is a company founded by a team of young engineers, that polarizes its own activity into designing and production devices dedicated to the world of applications of IoT. Thanks to the experience gained with CUBIT Innovation Lab and University of Pisa, SensorID has developed a strong know-how in wireless technology standard integration and implementation and in wireless network topology design. SensorID built a complete portfolio of embedded electronic modules based on NFC, UHF, RFID.

Near Field Communication (NFC) Technology represents short range (practically up to 4 cm) wireless communication offering safe yet simple and intuitive communication between electronic devices that we use on a daily basis. Users of devices having NFC application in it can simply touch their devices to other
similar elements having NFC application to communicate with them, making application and data usage easy and convenient. NFC can be called as the next generation of Radio Frequency Identification (RFID) as technically its working principal is based on RFID however from application point of view it is similar to Bluetooth in some ways since it allows communication between two active devices. NFC can be the future medium of contactless electronic payment as it inhibits eavesdropping on NFC - enabled transactions pertaining to its short range, however range can be extended by attackers using some range extension system. In this paper we briefly discussed the advantages, limits or challenges of NFC technology along with its applications which opens up exciting new usage scenarios for mobile devices.

Presentation for the 2012 Public Library Association conference in Philadelphia, PA.
A Librarian’s Field Guide to Near Field Communication
Near Field Communication (NFC) is a rising technology that allows mobile devices to exchange information wirelessly across a small distance. While it has many commercial applications
(e.g., using your cell phone as a credit card at the grocery
store), NFC could also have future applications for libraries as a new way to link physical materials with digital information. This presentation will discuss how NFC works; how it’s currently being used by merchants, advertisers, and gamers; and the impact it could have on libraries, librarians, and library patrons.

NEAR FIELD COMMUNICATION (NFC) TECHNOLOGY: A SURVEY IJCI JOURNAL
Near Field Communication, NFC- is one of the latest
short range wireless communication technologies.
NFC provides safe communication between electronic
gadgets. NFC-enabled devices can just be pointed or
touched by the users of their devices to other NFC-
enabled devices to communicate with them. With NFC
technology, communication is established when an NF
C-compatible device is brought within a few
centimetres of another i.e. around 20 cm theoretica
lly (4cm is practical). The immense benefit of the
short
transmission range is that it prevents eavesdroppin
g on NFC-enabled dealings. NFC technology enables
several innovative usage scenarios for mobile devic
es. NFC technology works on the basis of RFID
technology which uses magnetic field induction to c
ommence communication between electronic devices in
close vicinity. NFC operates at 13.56MHz and has 42
4kbps maximum data transfer rate. NFC is
complementary to Bluetooth and 802.11 with their lo
ng distance capabilities. In card emulation mode NF
C
devices can offer contactless/wireless smart card s
tandard. This technology enables smart phones to
replace traditional plastic cards for the purpose o
f ticketing, payment, etc. Sharing (share files bet
ween
phones), service discovery i.e. get information by
touching smart phones etc. are other possible
applications of NFC using smart phones. This paper
provides an overview of NFC technology in a detaile
d
manner including working principle, transmission de
tails, protocols and standards, application scenari
os,
future market, security standards and vendor’s chip
sets which are available for this standard. This
comprehensive survey should serve as a useful guide
for students, researchers and academicians who are
interested in NFC Technology and its applications [

NFC, short for Near Field Communication, is a short range wireless RFID technology that makes use of interacting electromagnetic radio fields instead of the typical direct radio transmissions used by technologies such as Bluetooth. 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

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
