Near field communication (NFC)

Near field communication ( NFC ) overview

The so-called near-field communication ( NFC ) technology is a kind of short distance high frequency wireless communication technology, available at a distance of about 10 cm, can realize electronic identification or data transmission, such as credit card, access control card and other functions. The early use of this technology, users can use mobile phone to replace public transportation card, bank card, staff card, access control card, membership card and contactless smart card, can easily read billboards on the fringe of the RFID tag information.

Now, with this kind of technology development and application, on mobile devices, consumer electronics, PC and intelligent control instrument for the short distance wireless communication. NFC provides a simple, touch solutions, so that consumers can easy to exchange information, access to the content and services.

Near field communication ( NFC ) technology in application of intelligent mobile phone

NFC has the advantages of low cost, easy to use and more intuitive features, which makes it in some areas appear more potential -- NFC through a chip, an antenna and a combination of software, to achieve a variety of equipment in a few centimeters within the scope of communication, and the cost is only 2 ~ 3 euros. According to ABIReasearch NFC new study, NFC market may rise in the handheld mobile device. ABI estimation, to 2005, the market will be using NFC chip intelligent mobile phone and enhanced handheld device. By 2009, the handheld device will account for more than half of the market. Research firm Strategy Analytics forecast, to 2011 global mobile phone based contactless payment forehead will exceed 36000000000 dollar. If the NFC technology can gain popularity, to a large extent it will change the way people use many electronic devices, and even change the use of credit cards, keys and cash. NFC as a new technology, broadly summarizes the Bluetooth technology collaborative work ability difference malady. However, it does not aim to be completely replaced by Bluetooth, Wi-Fi and other wireless technology, but on different occasions, different fields to play a complementary role. Because the NFC data transmission rate is low, only 212Kbps, not suitable for audio and video streaming, requires higher bandwidth applications.
