He aha te NFC? I roto i ngā kupu māmā noa iho, mā te whakauru i ngā mahi a te kaipānui kāri whakapūmau, te kāri whakapūmau me te whakawhitiwhiti kōrero ā-ira ki runga i te maramara kotahi, ka taea te whakamahi i ngā pūrua waea pūkoro hei whakatutuki i te utu waea pūkoro, te tuku tīkiti hiko, te whakahaere urunga, te tautuhi tuakiri waea pūkoro, te ārai i te tinihanga me ētahi atu tono. He maha ngā kaihanga maramara NFC rongonui i Haina, ko te nuinga ko Huawei hisilicon, Unigroup Guoxin, ZTE Microelectronics, Fudan Microelectronics me ētahi atu. He painga hangarau me ngā tūranga mākete tō ēnei kamupene i roto i te mara o ngā maramara NFC. Ko Huawei hisilicon tētahi o ngā kamupene hoahoa maramara whakawhitiwhiti kōrero nui rawa atu i Haina, ā, e mōhiotia ana āna maramara NFC mō te whakaurunga teitei me te mahi pumau. I tino pai hoki te mahi a Unigoup Guoxin, ZTE Microelectronics me Fudan Microelectronics i roto i te haumarutanga utu, ngā kaha tukatuka raraunga me ngā horopaki maha-tono. Ko te hangarau NFC e hangai ana ki te kawa whakawhitiwhiti kōrero ahokore 13.56 MHz, ā, ka taea te whakawhitiwhiti kōrero ahokore i waenga i ngā taputapu e rua e whakahohea ana e te NFC, kaua e neke atu i te 10 cm te tawhiti. He tino watea, kāore tēnei hononga e whakawhirinaki ki te Wi-Fi, 4G, LTE me ngā hangarau rite, ā, kāore he utu hei whakamahi: kāore he pūkenga kaiwhakamahi e hiahiatia ana; Kāore he pākahiko e hiahiatia ana; Kāore he ngaru RF e tukuna ana ina kore te kaipānui kāri e whakamahia ana (he hangarau kore mahi); Nā te rongonui o te hangarau NFC i roto i ngā waea atamai, ka taea e te katoa te pārekareka ki ngā painga o te NFC.
