Kodi NFC ndi chiyani? M'mawu osavuta, kuphatikiza ntchito za owerenga makhadi ochititsa chidwi, makhadi ochititsa chidwi komanso kulumikizana kwa point-to-point pa chip chimodzi, ma terminals am'manja atha kugwiritsidwa ntchito kuti akwaniritse kulipira kwa mafoni, ma tikiti apakompyuta, kuwongolera mwayi wopeza, chizindikiritso cha foni yam'manja, anti-counterfeiting. ndi ntchito zina. Pali opanga angapo odziwika bwino a NFC ku China, makamaka kuphatikiza Huawei hisilicon, Unigroup Guoxin, ZTE Microelectronics, Fudan Microelectronics ndi zina zotero. Makampaniwa ali ndi mwayi wawo waukadaulo komanso malo amsika pamsika wa tchipisi ta NFC. Huawei hisilicon ndi imodzi mwamakampani akuluakulu opanga zida zolumikizirana ku China, ndipo tchipisi take za NFC zimadziwika chifukwa chophatikizana kwambiri komanso kugwira ntchito mokhazikika. Unigoup Guoxin, ZTE Microelectronics ndi Fudan Microelectronics nawonso adachita bwino pachitetezo chamalipiro, kuthekera kosintha ma data ndi zochitika zamapulogalamu angapo, motsatana. Ukadaulo wa NFC umakhazikitsidwa pa njira yolumikizirana opanda zingwe ya 13.56 MHz ndipo imathandizira kulumikizana opanda zingwe pakati pa zida ziwiri zoyatsidwa ndi NFC osatalikirana ndi masentimita 10. Zosavuta kwambiri, kulumikizana uku sikudalira Wi-Fi, 4G, LTE kapena matekinoloje ofanana, ndipo sizimawononga chilichonse: palibe luso la ogwiritsa ntchito lomwe limafunikira; Palibe batire yofunika; Palibe mafunde a RF omwe amatulutsidwa pomwe owerenga makhadi sagwiritsidwa ntchito (ndiukadaulo wokhazikika); Ndi kutchuka kwaukadaulo wa NFC m'mafoni anzeru, aliyense akhoza kusangalala ndi zabwino za NFC.
