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.
The 'digital wallet' exists in the cloud, and it is not tethered to one specific device such as a mobile phone, but accessible from a variety of devices such as laptop, iPad, ultrabook or even Xbox.

Near Field Communications - NFC - Uses, Applications, Cost and Much More
- 1. Near Field Communication A Presentation By Praful K M
- 3. What Is NFC? ▪ NFC or Near Field Communication is a short range high frequency wireless communication technology. ▪ NFC is mainly aimed for mobile or handheld devices.
- 4. What Is NFC? ▪ A radio communication is established by touching the two phones or keeping them in a proximity of a few centimetres (up to 10 cm) . ▪ Logo Allows communication between Two powered (active) devices Powered and non self-powered (passive) devices
- 6. Evolution ▪ In 2004, NFC Forum was formed by Nokia, Philips, Sony, to set standards for NFC . Every NFC enabled device will have “N-Mark” trademark ,developed by NFC Forum.
- 7. Evolution ▪ In 2006 First mobile phone( Nokia 6131) with NFC released by NOKIA.
- 8. Evolution ▪ In 2010 First android phone SAMSUNG NEXUS S with NFC support released.
- 9. Features of Near Field Communications
- 10. Features ▪ NFC is an extension of Radio frequency identification (RFID) technology that combines the interface of a smartcard and a reader into a single device. ▪ This allow two-way communication between endpoints, where earlier systems were one-way only.
- 11. Features ▪ It operates within the globally available and unlicensed radio frequency band of 13.56 MHz, with a bandwidth of 14 kHz. ▪ Working distance with compact standard antennas: up to 10 cm .
- 12. Features ▪ Supported data rates: 106, 212 and 424K bit/s For two devices to communicate using NFC, one device must have an NFC reader/writer and one must have an NFC tag
- 14. Operation ▪ NFC has two communicative terminals :The INITIATOR is the one who wishes to communicate and starts the communication. The TARGET receives the initiator’s communication request and sends back a reply
- 15. Operation ▪ NFC employs two different coding to transfer data. If an active device transfers data at 106 Kbit/s, a Modified Miller coding with 100% modulation is used. In all other cases Manchester coding is used with a modulation ratio of 10%.
- 16. Active Communication Mode ▪ In Active mode, both devices with NFC chip generates an electromagnetic field and exchange data.
- 17. Passive Communication Mode ▪ In Passive mode, there is only one active device and the other uses that field to exchange information.
- 18. Operation ▪ NFC devices communicate via magnetic field induction, where two loop antennas are located within each others near field, effectively forming an air-core transformer. ▪ The reader continuously generates an RF carrier sine wave (at 13.56MHz), watching always for modulation to occur. Detected modulation of the field would indicate the presence of a tag.
- 19. Operation ▪ A tag enters the RF field generated by the reader. ▪ Once the tag has received sufficient energy to operate correctly, it divides down the carrier and begins clocking its data to an output transistor, which is normally connected across the coil inputs.
- 20. Operation ▪ The tag’s output transistor shunts the coil, sequentially corresponding to the data which is being clocked out of the memory array. ▪ Shunting the coil causes a momentary fluctuation (dampening) of the carrier wave, which is seen as a slight change in amplitude of the carrier. ▪ The reader peak-detects the amplitude modulated data and processes the resulting bit stream according to the encoding and data modulation methods used.
- 22. Touch And Go
- 25. Operating Modes Of NFC Devices
- 26. Reader/Writing Mode ▪ Reader/writer mode the NFC device is capable of reading NFC Forum- mandated tag types, such as a tag embedded in an NFC smart poster.
- 27. Peer-to-Peer Mode ▪ Peer-to-Peer mode Two NFC devices can exchange data. For example, you can share Bluetooth or Wi-Fi link set-up parameters or you can exchange data such as virtual business cards or digital photos.
- 28. Card Emulation Mode ▪ Card Emulation mode The NFC device appears to an external reader much the same as a traditional contactless smart card. This enables contactless payments and ticketing by NFC devices without changing the existing infrastructure.
- 30. Merits & Demerits Of NFCs
- 31. Merits ▪ High convenience to the user, because the data exchange is done by bringing two mobiles together ▪ Reduces cost of electronic issuance ▪ Secure communication ▪ No special software ▪ No manual configuration and settings ▪ No search and pair procedure
- 32. Demerits ▪ The system has the limitation that it can be operated only with devices under a short range i.e. around 10 cm. ▪ The data transfer rate is very less at about 106kbps, 212 kbps and 424kbps.
