Near Field Communication (NFC)
NFC is a short-range wireless communication technology that allows data exchange between devices within 10 cm of each other. It evolved from RFID technology. Nokia launched the first mobile phone with NFC. NFC operates at 13.56 MHz and works by one device having an NFC reader/writer and the other an NFC tag. Applications include transferring files between phones, downloading content from smart posters, exchanging contact info, and mobile payments for transportation and purchases. Advantages are convenience without pairing and versatility, while disadvantages are security, cost, short range, and lower data rates.
10.1
NFC uses magnetic field induction at 13.56 MHz to allow communication between devices over short distances of 0-20 cm. It operates at speeds of 106-424 kbps. NFC has two modes, active communication mode and passive communication mode. It is compared to RFID and Bluetooth, with NFC having shorter ranges but faster setup times than RFID and lower costs than Bluetooth. The main uses of NFC include card mode, reader mode, and peer-to-peer mode. Common applications are mobile payments, ticketing, identity documents, and electronic keys.

In this paper we describe the design and implementation of a new versatile, scalable and cost-effective sensate surface. The system is based on a new conductive inkjet technology, which allows capacitive sensor electrodes and different types of RF antennas to be cheaply printed onto a roll of flexible substrate that may be many meters long. By deploying this surface on (or under) a floor it is possible to detect the presence and whereabouts of users through both passive and active capacitive coupling schemes. We have also incorporated GSM and NFC electromagnetic radiation sensing and piezoelectric pressure and vibration detection. We report on a number of experiments which evaluate sensing performance based on a 2.5m x 0.3m hardware test-bed. We describe some potential applications for this technology and highlight a number of improvements we have in mind.

It uses magnetic field induction to enable communication between electronic devices like mobile phones and readers for contactless transactions. Some key applications of NFC include touch-and-go payments, contactless ticketing/access, and data sharing by touching two NFC devices. While convenient, NFC also faces security risks like eavesdropping and data theft that require technical solutions like encryption.
Near field communication.pptx
NFC traces its roots back to radio-frequency identification, or RFID. RFID allows a reader to send radio waves to a passive electronic tag for identification, authentication and tracking.
2004 Nokia, Philips and Sony established the Near Field Communication (NFC) Forum.
2006 Initial specifications for NFC Tags.
2006 Nokia 6131 was the first NFC phone.
2009 In January, NFC Forum released Peer-to-Peer standards to transfer contact, URL, initiate Bluetooth, etc.
2010 Samsung Nexus S: First Android NFC phone shown.
2013 Samsung and Visa announce major partnership to develop mobile payments
NFC was approved as an ISO/IEC standard on December 8, 2003 and later as an ECMA standard.
ISO/IEC 18092 / ECMA-340 - Near Field Communication Interface and Protocol-1 (NFCIP).
ISO/IEC 21481 / ECMA-352 - Near Field Communication Interface and Protocol-2 (NFCIP-2).
NFC incorporates a variety of existing standards including ISO/IEC 14443.
In addition, the NFC Forum has defined a common data format called NFC Data Exchange Format (NDEF).
As with proximity card technology, near-field communication uses magnetic induction between two loop antennas located within each other's near field, effectively forming an air-core transformer.
NFC always involves an initiator and a target; the initiator actively generates an RF field that can power a passive target.
This enables NFC targets to take very simple form factors such as tags, stickers, key fobs, or cards that do not require batteries.
NFC peer-to-peer communication is possible, provided both devices are powered.
Most of the RF energy is concentrated in the allowed ±7 kHz bandwidth range, but the full spectral envelope may be as wide as 1.8 MHz when using ASK modulation
NFC is a set of short-range wireless technologies, typically requiring a distance of 10 cm or less.
NFC operates at 13.56 MHz on ISO/IEC 18000-3 air interface and at rates ranging from 106 kbit/s to 424 kbit/s.
It operates within the globally available and unlicensed radio frequency ISM band of 13.56 MHz.
Theoretical working distance with compact standard antennas: up to 20 cm (practical working distance of about 4 cm).
Supported data rates: 106, 212 or 424 kbit/s (the bit rate 848 kbit/s is not compliant with the standard ISO/IEC 18092).
NFC devices are able to receive and transmit data at the same time.

Near field communication (NFC) is a set of standards for smartphones and similar devices to establish
nfc
NFC is wireless technology which provides communication between two mobile phones which
contain NFC tags, using short range radio waves. It uses the magnetic field induction for this purpose. Both devices can communicate with each other using NFC technology when they touch each other or brought very close to each other. It requires short range of approximately ten centimeters to perform the exchange of information between two devices.
We can do payment using our NFC enabled phone by swiping it out in front of the phone reader and then the purchase price will automatically paid from credit card or debit card. Our mobile phone can be used in place of wallet, credit cards, debit cards etc. We don’t need to carry our credit card or debit card with us. But with these advantages, we will have to face disadvantages too. There are some security threats to NFC technology, which should be prevented.
NFC technology uses RFID (Radio Frequency Identification) for data/information exchange between two devices over a short distance like Bluetooth and Wi-Fi technology. NFC enabled smartphone users can make transactions and access information with only a simple touch. NFC devices can send and receive data simultaneously. So this technology has a very bright future scope. Since it is a new technology, so NFC enabled mobile users need to be educated on how it will work for them to make payment or exchange any information. But there is a requirement of a protected infrastructure for NFC technology so that it could be widely adopted all over the world. This technology has several advantages over other wireless technology because it provides bidirectional communication for exchanging information.
For example if someone have a laptop and cell phone equipped with NFC, then he/she can easily download data from Internet into the cell phone by simply touching
the cell phone with laptop. Like that you may take pictures by the cell phone and if you want to show those pictures to your friends on big screen then you may just touch your phone with TV and show them. Or if you want to print those pictures then by touching the cell phone with NFC equipped printer will give you the prints of those pictures. This principle works with any kind of
devices equipped with NFC to communicate with each other.
It’s operating frequency is 13.56MHz. Working distance with compact standard antennas is up to 10 cm. The rate of transfer of data is around 106 to 424 Kbit/s. For two devices to communicate using NFC, one device must have an NFC reader/writer and one must have an NFC tag.

- 2. HELLO!Our team : Sunny Baniya Tulsa Khadka Sumir Acharya 2
- 3. Near Field Communication Let’s start with the first set of slides 3 1
- 4. WHAT IS NFC ? ▰ NFC or Near Field Communication is a short range high frequency wireless communication technology. ▰ A radio communication is established by touching the two phones or keeping them in proximity of few centimeters. ▰ NFC is mainly aimed for mobile or handless devices ▰ NFC is an extension of Radio Frequency identification or RFID technology. ▰ RFID is mainly used for tracking and identification by sending radio waves. 4
- 5. OPERATION OF NFC ▰Near Field Communication is based on inductive-coupling. ▰NFC works using magnetic induction between two loop antennas located within each other’s ‘near field’. 5
- 6. FEATURES OF NFC 6 Based on RF technology. Uses the global 13.56 MHz allocation. Working distance : Up to to 20cm ( for security oriented connection up to 4cm) Supported Data Rates : 106,212 or 424 Kbit/s
- 7. Passive Device A passive device, such as an NFC tag, contains information that other devices can read but does not read any information itself. Think of a passive device as a sign on a wall. Others can read the information, but the sign itself does nothing except transmit the info to authorized devices. NFC Device Active Device Active devices can read information and send it. An active NFC device, like a smart phone, would not only be able to collect information from NFC tags, but it would also be able to exchange information with other compatible phones or devices and could even alter the information on the NFC tag if authorized to make such changes. 7
- 8. NFC- MODES OF OPERATION PEER TO PEER MODE Two powered devices can engage in peer-to-peer mode, which is NFC specific. During the initial communication, the two devices determine the communication parameters, such as data block size. The maximum data block size is 256 bytes. READER / WRITER MODE When working in reader/writer mode, most NFC devices act as readers. The NFC device works in active mode to read the content of a tag. When it detects two or more tags, it relies on an anti-collision algorithm to select just one tag. An NFC device can also write data to the tag. CARD EMULATION MODE This mode places the NFC device in passive communication mode. The device acts precisely the same as a smart card. Your NFC-enabled device can emulate more than one smart card, and the smart card support can include more than one form of identification. 8
- 9. ADVANTAGES & DISADVANTAGES ADVANTAGES : ▰ Convenient ▰ Versatile ▰ Better User Experience ▰ Seamless ▰ More Secure DISADVANTAGES : ▰ Expensive ▰ Not Advantageous Enough ▰ Lack of Security 9
- 10. NFC IN PICTURE : SMART PICTURE (NFC Tags) The small size of NFC tags and their lack of a battery, relying instead on radio frequency signals sent from a smartphone or other NFC compatible device to operate, let them go virtually anywhere. From posters to museum displays to library books, an NFC tag can hold information that a user can then swipe their phone over to read. From art galleries to schools, NFC tags are used to transmit information about famous artworks or display personalized student schedules and current event updates. 10
