He aha ka NFC? Ma nā huaʻōlelo maʻalahi, ma ka hoʻohui ʻana i nā hana o ka mea heluhelu kāleka inductive, kāleka inductive a me ke kamaʻilio kiko-a-kiko ma kahi chip hoʻokahi, hiki ke hoʻohana ʻia nā kikowaena kelepona e hoʻokō i ka uku kelepona, ka tiketi uila, ka mana komo, ka ʻike ʻike kelepona, ka anti-counterfeiting a me nā noi ʻē aʻe. Aia kekahi mau mea hana chip NFC kaulana ma Kina, ʻo ia hoʻi ʻo Huawei hisilicon, Unigroup Guoxin, ZTE Microelectronics, Fudan Microelectronics a pēlā aku. Loaʻa i kēia mau hui kā lākou mau pono loea 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 ua ʻike ʻia kāna mau chips NFC no ka hoʻohui kiʻekiʻe a me ka hana paʻa. Ua hana koʻikoʻi ʻo Unigoup Guoxin, ZTE Microelectronics a me Fudan Microelectronics i ka palekana uku, nā hiki ke hana ʻikepili a me nā hiʻohiʻona multi-application, kēlā me kēia. Hoʻokumu ʻia ka ʻenehana NFC ma ka protocol kamaʻilio uea ʻole 13.56 MHz a hiki i ka kamaʻilio uea ʻole ma waena o ʻelua mau mea i hiki i ka NFC ʻaʻole i ʻoi aku ma mua o 10 cm ke kaʻawale. He kūpono loa, ʻaʻole hilinaʻi kēia pilina ma Wi-Fi, 4G, LTE a i ʻole nā ​​​​ʻenehana like, a ʻaʻohe uku e hoʻohana ai: ʻaʻohe pono o nā mākau mea hoʻohana; ʻAʻohe pono o ka pākaukau; ʻAʻohe nalu RF e hoʻopuka ʻia ke hoʻohana ʻole ʻia ka mea heluhelu kāleka (he ʻenehana passive ia); Me ke kaulana o ka ʻenehana NFC i nā kelepona akamai, hiki i nā mea āpau ke hauʻoli i nā pono o NFC.
