| 近場(chǎng)通信Near Field Communication，縮寫為NFC。近場(chǎng)通信又稱近距離無(wú)線通信，是一種短距離的高頻無(wú)線通信技術(shù)，允許電子設(shè)備之間進(jìn)行非接觸式點(diǎn)對(duì)點(diǎn)數(shù)據(jù)傳輸，交換數(shù)據(jù)。
通信不一定非要在兩個(gè)手持設(shè)備之間進(jìn)行，例如兩個(gè)手機(jī)之間。它還可以在移動(dòng)設(shè)備和某些目標(biāo)上工作，例如商店收銀臺(tái)的銷售終端系統(tǒng)，內(nèi)置有近場(chǎng)通信芯片的標(biāo)簽、商標(biāo)標(biāo)簽、海報(bào)、印花或者卡片。對(duì)于這些簡(jiǎn)單的目標(biāo)，近場(chǎng)通信芯片無(wú)需電池支持。相反，芯片處于被動(dòng)狀態(tài)，可通過(guò)另一個(gè)設(shè)備產(chǎn)生無(wú)線射頻場(chǎng)進(jìn)行激活。NFC近場(chǎng)通信技術(shù)將會(huì)從各個(gè)方面改變?nèi)藗兊囊苿?dòng)生活，例如商務(wù)汽車存取，通過(guò)Foursquare之類的LBS應(yīng)用簽到，甚至可以完全取代你的錢包，信用卡、借記卡、現(xiàn)金、優(yōu)惠券一應(yīng)俱全。
英文：
Near Field Communication Near Field Communication abbreviation for the NFC. Near Field Communication, also known as short-range wireless communication, is a short-range high frequency wireless communication technology that allows non-contact point-to-point data transmission, exchange of data between electronic devices.
Communication between two handheld devices do not have to, for example between the two mobile phone. It can also work in mobile devices, and certain goals, such as store cashier's sales terminal system, built-in near-field communication chip labels, trademark labels, posters, printing or card. These simple goals, near-field communication devices do not require battery support. Instead, the chip passive state, can activate the radio frequency field generated by another device. NFC Near Field Communication technology will change people's mobile life in all its aspects, such as commercial vehicle access, attendance by the Foursquare class LBS application can even replace your wallet, credit cards, debit cards, cash, coupons should taste. |
