He aha ka NFC? Ma nā ʻōlelo maʻalahi, ma ka hoʻohui ʻana i nā hana o ka mea heluhelu kāleka inductive, kāleka inductive a me ke kamaʻilio point-to-point ma kahi pahu hoʻokahi, hiki ke hoʻohana ʻia nā terminal mobile e hoʻokō ai i ka uku kelepona, ka leka uila, ka mana komo, ka ʻike ʻike kelepona, anti-counterfeiting. a me nā noi ʻē aʻe. Nui nā mea hana chip NFC kaulana i Kina, ʻo ia hoʻi me Huawei hisilicon, Unigroup Guoxin, ZTE Microelectronics, Fudan Microelectronics a pēlā aku. Loaʻa i kēia mau ʻoihana kā lākou pono ponoʻī ʻenehana a me nā kūlana mākeke ma ke kahua o nā chips NFC. ʻO Huawei hisilicon kekahi o nā hui hoʻolālā chip kamaʻilio nui loa ma Kina, a ʻike ʻia kāna mau chip NFC no ka hoʻohui kiʻekiʻe a me ka hana paʻa. ʻO Unigoup Guoxin, ZTE Microelectronics a me Fudan Microelectronics kekahi i hana koʻikoʻi i ka palekana uku, ka hiki ke hoʻoili ʻikepili a me nā hiʻohiʻona noiʻi lehulehu. Hoʻokumu ʻia ka ʻenehana NFC ma luna o ka protocol kamaʻilio uea 13.56 MHz a hiki ke kamaʻilio uea ma waena o ʻelua mau mea hoʻohana i ka NFC ʻaʻole i oi aku ma mua o 10 knm kaawale. Maikaʻi loa, ʻaʻole hilinaʻi kēia pilina ma Wi-Fi, 4G, LTE a i ʻole nā ​​ʻenehana like ʻole, a ʻaʻohe kumu kūʻai no ka hoʻohana ʻana: ʻaʻohe pono o ka mea hoʻohana; ʻAʻole pono ka pila; ʻAʻole hoʻokuʻu ʻia nā nalu RF ke hoʻohana ʻole ʻia ka mea heluhelu kāleka (he ʻenehana passive ia); Me ka kaulana o ka ʻenehana NFC i nā kelepona akamai, hiki i nā mea a pau ke hauʻoli i nā pono o ka NFC.
