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

Near field communication - Data transmission
Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communication with each other by touching them together or bringing them into proximity, usually no more than a few inches.
NFC
NFC allows for simple data exchange between two devices through physical touch. It requires an initiator that generates an RF field within 4 cm, and a target that receives the data. NFC enables uses like contactless payments, data sharing between devices, and interacting with NFC tags. It provides intuitive, secure communication at short ranges and works with existing contactless standards. Benefits include intuitive interactions with a touch, versatility across industries, and inherent security through short transmission distances.
Near Field Communication (NFC)
Near field communication (NFC) is a short-range wireless technology that allows data exchange between devices within 20 centimeters of each other. It uses RFID technology to enable communication between devices, with one device needing an NFC reader/writer and the other an NFC tag. Initial rollouts on mobile phones enabled displaying and storing data. By 2013, one in five phones were projected to have NFC, enabling uses like mobile payments. While offering convenient contactless payments, NFC also raises security issues like eavesdropping, data modification, and relay attacks that applications aim to prevent.

NFC uses magnetic field induction to enable communication between NFC-enabled devices and is compatible with existing RFID infrastructure. Current and anticipated applications of NFC include contactless payments, transport fares, exchanging contact information, accessing digital content, and more. While providing convenient connectivity, NFC also faces security threats like eavesdropping and data modification if not implemented securely.

Overall, the document concludes that NFC will provide convenience for consumers and retailers.
RFID: a condensed overview
RFID is a system that uses radio waves to wirelessly transmit data between a tag and reader. It has advantages over barcodes like not needing line of sight and ability to read/write data. There are different types of tags based on power source and range. Common frequencies used are low, high and ultra-high frequency. RFID is used for applications like asset tracking, process control, data lineage tracing and automated replenishment. The Internet of Things connects physical objects through embedded technology like sensors to exchange data. Near Field Communication is a short-range wireless technology that allows data exchange when devices are 10cm apart and is used for contactless payments, ticketing and access control.

Near field communication(NFC)
Near Field Communication (NFC) is a short-range wireless technology that allows data exchange between devices within 10 cm of each other. NFC was developed from RFID technology and operates at 13.56 MHz. It enables simplified transactions, data exchange, and wireless connections. NFC supports three operating modes - card emulation, peer-to-peer, and reader/writer - and has applications in areas like mobile payments, ticketing, and data sharing between devices. While convenient, NFC has limitations in range and data transfer speed.

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.
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.
