NFC(Near Field Communication)

NFC is Near Field Communication abbreviations, by philips and SONY NFC joint exploration is a non-contact recognition and Internet technology, can be in mobile devices, consumer electronic products, PC and intelligent control tool room close wireless Communication. NFC provides a simple and touch solutions, can let consumer simple intuitively exchange information, visit content and service.

summary

NFC will non-contact card reader, non-contact card and peer-to-peer (Peer to Peer) - - functional integration into a single chip, for consumer lifestyle pioneered the countless new opportunities. It is an open interface platform, we can in wireless networks for rapid, active Settings, is virtual connectors, serve our current cellular network, bluetooth and wireless 802.11 equipment.

NFC compatible with SONY FeliCaTM card and has been widely establish non-contact smart architecture, this framework based on ISO 14443 A, use philips' MIFARE? Technology.

In order to promote the development and popularization of NFC, philips, SONY and nokia create a nonprofit industry association - BBS, promote NFC NFC implement technology and standardization, ensure the equipment and services coordination between cooperation. At present, NFC BBS employs more than 70 members, including: mastercard international organizations, panasonic electronic industrial Co., LTD, Microsoft corporation, MOTOROLA, NEC corporation, renesas technology companies, samsung, Texas instruments manufacturing firms, and Visa international organizations.

Editor's note: the world's first commercial NFC release: * Germany, mainz transportation company (RMV) on April 19, 2006, philips, nokia, Vodafone company and Frankfurt mainz area of bus network operators mainz transportation company (Rhein - Main Verkehrsverbund) announced that in successfully for 10 months after the field test, close (NFC) wireless communication technology is commercially available. At present, Nokia cellular phone already 3,220 has integrated NFC technology, can be used as electronic ticket, but also in the local retail and tourist attractions as discount loyalty card use. Ha Nao city is now just about 95.000 bits residents easily brush compatible mobile phone, you can enjoy NFC type bus ticket the convenience of mobile.

Technical advantages

As with RFID NFC information is through radio frequency spectrum in part of the electromagnetic induction coupling between style to deliver, but there are still very big difference. First, provide NFC is a kind of comfortable, safe, rapid communication wireless connection technology, its transmission range than RFID small, RFID transmission range can achieve a few meters, even a few meters, but because NFC adopted unique signal attenuation, relative to the RFID technology for NFC has closer, bandwidth high, low energy consumption characteristics. Secondly, NFC with existing non-contact smart card technology compatible, now has become main manufacturer support by more and more formal standards. Again, NFC or a close link protocol, provide various equipment room comfortable, safe, rapid and automatic communications. With the wireless world of the connection method, compared to other NFC is a kind of close illicit close communication mode. Finally, RFID more to be used in production, logistics and tracking, asset management, and is in the entrance guard, NFC bus, mobile payment in fields plays a tremendous role.

Meanwhile, NFC still better than infrared and bluetooth transmission mode. As a kind of face consumer to trading mechanism, NFC than infrared faster, more reliable and much more simple, need not to infrared that must be strictly aligned to transmit data. Compared with bluetooth NFC face close trade, applicable to exchange financial information or sensitive personal information and other important data; Bluetooth could make up for the defect that NFC communication distance, suitable for a long distance data communication. Therefore, bluetooth NFC and complement each other, in together. In fact, quick lightweight NFC agreement can be used to guide the bluetooth pairing between two equipment, promote the process of bluetooth use.

Mobile phone build-in NFC NFC chip, component part of RFID module, can regard as RFID passive tags used to pay cost; -- Also can be used as RFID literacy generator - - used as data exchange and acquisition. NFC technology supports multiple applications, including mobile payment and transaction, mobile communication and to equation of information access, etc. Through NFC mobile phone, people can at any place and at any time through any equipment, and they hope to get the entertainment services and trading relates in together, thus finish the payment, obtain the poster information, etc. NFC equipment can be used as a non-contact smart CARDS, smart card's reading and writing implement terminal and equipment on equipment data transmission link, its application in mainly divided into the following four basic types: used for payment and tickets, used in electronic ticket, for intelligent media and used to exchange, data transmission.

Development prospect

NFC with low cost and easy to use and more rich visual features, this makes it in some areas appear more potential -- NFC through a chip, a single antenna and some software, can realize the combination of all kinds of equipment in a few centimeters within the scope of the communication, and the costs only for 2 ~ 3 euros. According to relevant ABIResearch NFC have the latest research, NFC markets may was elected on mobile hand-held devices. ABI estimates that by 2005, the market will appear after using NFC chip smartphone and enhanced hand-held devices. By 2009, the hand held device will account for more than half of the market. Research institutions focussing Analytics forecast, until 2011 global based on mobile phone contactless payment will be more than 360 million dollars. If NFC technology to get popular, it will be largely change people use many electronic equipment, even the way change use credit CARDS and keys and cash way. NFC as a new technology, generally summarized the bluetooth technology interoperability poor ills. However, the objective of which is not completely replace the bluetooth, Wi - Fi and other wireless technology, but in different occasions, different fields have mutually supplementary role. Because NFC data transfer rate is low, only for 212Kbps, is not suitable for such as audio and video stream etc have higher bandwidth applications.
