What is Near field communication (NFC)...

and Similarity with OBAMA's RFID CHIPS...

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. 

Here's the controversial RFID Chips. 

Obama Health Care Bill mandates Microchip implementation for all American citizens living in the U.S. by March, 23rd 2013 stipulated in H.R. 3200 section 2521, Pg. 1001, paragraph 1. and on Page 1004 of the new law (dictating the timing of this chip), reads,  "No later than 36 months after the date of the enactment" .

 

More on NFC...
 
 
Near field communication (NFC) is a set of standards for smartphones and similar devices to establish radio communcation with each other by touching them together or bringing them into close proximity, usually no more than a few centimetres. 







Present and anticipated applications include contactless transactions, data exchange, and simplified setup of more complex communications such as Wi-Fi. 

Communication is also possible between an NFC device and an unpowered NFC chip, called a "tag".

The NFC Ecosystem

The potential for NFC applications and products is broad and deep, whether you’re leveraging the promise of peer-to-peer Bluetooth communications, developing payment system applications, or creating the chips that will enable upcoming NFC-based products.

The NFC Forum Helps Build the Ecosystem

The Forum’s membership covers all parts of the NFC ecosystem. These companies share their development, application, and marketing expertise to develop the best possible solutions for advancing the use of NFC. All decisions are approved by the voting membership to ensure that a wide range of perspectives are included in order to build a firm and flexible foundation for all future NFC market growth.

The NFC Ecosystem
The NFC Forum’s membership includes organizations  from every sector of the NFC ecosystem

Participate in the NFC Forum The NFC Forum welcomes participation from all organizations interested in helping to build the NFC market and ecosystem.

By joining the 160+ members of the NFC Forum and taking advantage of numerous opportunities to meet each year at NFC Forum meetings and Forum sponsored events, you will be able to build relationships, partnerships, and a wealth of business opportunities.

Essential specifications

NFC is a set of short-range wireless technologies, typically requiring a distance of 4 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. 

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. A patent licensing program for NFC is currently under development by Via Licensing Corporation, an independent subsidiary of Dolby Laboratories. A public, platform-independent NFC library is released under the free GNU Lesser General Public License by the name libnfc.

NFC tags contain data and are typically read-only, but may be rewriteable. They can be custom-encoded by their manufacturers or use the specifications provided by the NFC Forum, an industry association charged with promoting the technology and setting key standards. The tags can securely store personal data such as debit and credit card information, loyalty program data, PINs and networking contacts, among other information. 

The NFC Forum defines four types of tags that provide different communication speeds and capabilities in terms of configurability, memory, security, data retention and write endurance. Tags currently offer between 96 and 4,096 bytes of memory.

• 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. It operates within the globally available and unlicensed radio frequency ISM band of 13.56 MHz. 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.
• Theoretical working distance with compact standard antennas: up to 20 cm (practical working distance of about 4 centimetres)
• 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 Mobile Payments : 

A new dimension to shopping

Uploaded by logicatvic on Feb 18, 2010

Mobile phone replaces PIN debit card at supermarket: Logicas unique project with the world’s first mobile integration of two different applications of the NFC technology being tested in real-life conditions. This was the first use of NFC in financial transactions whereby the mobile phone acted as replacement for the traditional online debit card (in this case, PIN). Additionally, users are offered a taste of the wide range of other possible applications by also being able to use the mobile phone as a repository of bottle return refunds. This enabled the user to wirelessly receive, save, transfer and use their refunds.

• There are two modes:
• Passive communication mode: The initiator device provides a carrier field and the target device answers by modulating the existing field. In this mode, the target device may draw its operating power from the initiator-provided electromagnetic field, thus making the target device a transponder.
• Active communication mode: Both initiator and target device communicate by alternately generating their own fields. A device deactivates its RF field while it is waiting for data. In this mode, both devices typically have power supplied

• NFC employs two different codings 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%.
• NFC devices are able to receive and transmit data at the same time. Thus, they can check for potential collisions, if the received signal frequency does not match with the transmitted signal's frequency.
