Kodi NFC ndi chiyani? Mwachidule, pophatikiza ntchito za inductive card reader, inductive card ndi point-to-point communication pa chip imodzi, ma mobile terminals angagwiritsidwe ntchito kukwaniritsa malipiro a pafoni, electronic tickets, access control, mobile identity identity, anti-counterfeiting ndi mapulogalamu ena. Pali opanga ma NFC chip ambiri odziwika bwino ku China, makamaka kuphatikiza Huawei hisicon, Unigroup Guoxin, ZTE Microelectronics, Fudan Microelectronics ndi zina zotero. Makampaniwa ali ndi ubwino wawo waukadaulo komanso malo awo pamsika wa ma NFC chips. Huawei hisicon ndi imodzi mwa makampani akuluakulu opanga ma chips olumikizirana ku China, ndipo ma NFC chips ake amadziwika kuti ndi ogwirizana kwambiri komanso amagwira ntchito bwino. Unigoup Guoxin, ZTE Microelectronics ndi Fudan Microelectronics nawonso adachita bwino kwambiri pachitetezo cha malipiro, kuthekera kokonza deta komanso zochitika zambiri, motsatana. Ukadaulo wa NFC umachokera pa protocol yolumikizirana yopanda zingwe ya 13.56 MHz ndipo umalola kulumikizana popanda zingwe pakati pa zida ziwiri zoyendetsedwa ndi NFC zosapitirira 10 cm. Ndi yosavuta, kulumikizana kumeneku sikudalira Wi-Fi, 4G, LTE kapena ukadaulo wina wofanana, ndipo sikuwononga ndalama kugwiritsa ntchito: palibe luso la ogwiritsa ntchito lomwe likufunika; Palibe batire yofunikira; Palibe mafunde a RF omwe amatuluka ngati wowerenga khadi sakugwiritsidwa ntchito (ndi ukadaulo wosagwiritsidwa ntchito); Ndi kutchuka kwa ukadaulo wa NFC m'mafoni anzeru, aliyense akhoza kusangalala ndi ubwino wa NFC.
