Ua maʻa mākou a pau i kahi hiʻohiʻona i loko o kahi kelepona e like me NFC. A ua maopopo nā mea a pau me kēia.
ʻAʻole kūʻai nā poʻe he nui i nā kelepona me ka ʻole o NFC, me ka manaʻo e pili ana i ke kūʻai ʻana. Akā, nui nā nīnau.
Akā, ua ʻike anei ʻoe i nā mea ʻē aʻe e hiki ai i kēia ʻenehana ke hana? He aha kāu e hana ai inā ʻaʻohe NFC i kāu kelepona? Pehea e hoʻohana ai i ka chip ma iPhone ʻaʻole wale no Apple Pay? No ke aha e hana ʻole ai, ʻoi aku me nā kāleka honua?
Hiki iā ʻoe ke hoʻouka i nā polokalamu ma o ia ...
I kēia lā e haʻi mākou iā ʻoe pehea e hana ai a nānā i nā kikoʻī āpau. A ʻo ka mea nui loa, no ke aha ʻo ia ka ʻenehana haʻahaʻa loa i kāu kelepona!
Pehea e hana ai ka NFC?
ʻIke paha ʻoe ʻo ka NFC ke kū nei no Near Field Communication a i ʻole ma ka ʻōlelo Lūkini - kamaʻilio pōkole.
Akā ʻaʻole kēia ka hoʻoili ʻikepili maʻamau ma luna o kahi nalu lekiō. ʻAʻole like me Wi-Fi a me Bluetooth, ʻoi aku ka maʻalahi o ka NFC. Hoʻokumu ʻia ia ma ka induction electromagnetic. He mea ʻoluʻolu loa kēia mai ke kula haʻawina, e hoʻomanaʻo wau iā ʻoe.
ʻO ka manaʻo e lawe ʻoe i hoʻokahi conductor me ka uila ʻole. A kau ʻoe i kahi mea hoʻokele lua ma hope ona, aia ka uila. A manaʻo he aha? I ka conductor mua, kahi i ʻole ka uila, hoʻomaka ke kahe e kahe!
Maikaʻi, ʻae?
I ko mākou aʻo mua ʻana, manaʻo mākou he mea hiki ʻole! ʻOiaʻiʻo? Ke kalaiwa nei ʻoe! E hele kāua e pāʻani i ka Counter Strike, e nā keikikāne.
ʻAe, ke lawe ʻoe i kāu kelepona i kahi hōʻailona NFC me ka ʻole o ka mana, ua lawa kēia kahua electromagnetic liʻiliʻi mai ke kelepona no nā electrons e kahe i loko o ka tag a me nā microcircuits i loko e hana.
ʻAe. Loaʻa i kēlā me kēia lepili kahi puʻupuʻu liʻiliʻi. No ka laʻana, ma nā kāleka panakō holo ka microchip i kahi mana maʻalahi o Java. Pehea ke ano?
Ua lohe paha ʻoe i ka pōkole RFID. Ua kūkulu ʻia he 30 mau makahiki ma mua. Kū ia no Radio Frequency Identification. A ʻoiaʻiʻo, kūpono wale ia no ka ʻike. He nui nā keʻena keʻena i loaʻa nā hōʻailona RFID.
No laila ʻo NFC kahi lālā holomua o ka maʻamau RFID a heluhelu i kekahi o kēia mau hōʻailona. Akā ʻo ka ʻokoʻa nui hiki iā NFC ke hoʻoili i ka ʻikepili, me nā mea i hoʻopili ʻia.
Hoʻohana ʻo NFC i ke alapine o 13,56 MHz, kahi e hiki ai iā ʻoe ke hoʻokō i nā wikiwiki maikaʻi mai 106 a 424 Kbps. No laila e hoʻoiho ʻia ka faila mp3 i ʻelua mau minuke, akā ma kahi mamao a hiki i 10 cm.
Ma ke kino, ʻo ka NFC kahi wili liʻiliʻi. No ka laʻana, ma Pixel 4 ua hoʻopili ʻia i ka poʻi a like me kēia.
A pēlā ma Xiaomi Mi 10 Pro:
A ʻo kēia ka manawa e kamaʻilio e pili ana i ka mea hiki ke hana ʻo NFC?
ʻO ka hana o kēia ʻenehana a me nā mea e pili ana, e like me RFID, ua wehewehe ʻia i ka maʻamau ISO 14443. Nui nā mea i hui pū ʻia: no ka laʻana, ʻo ka Italian Mifare protocol a me VME aia i nā kāleka panakō.
ʻO NFC ke ʻano o ka USB Type-C o ka honua uila, inā ʻike ʻoe i kaʻu ʻōlelo.
Akā ʻo ka mea nui kēia. Hiki iā NFC ke hana i ʻekolu mau ʻano:
- ʻEleu. Ke heluhelu a kākau paha kekahi mea i ka ʻikepili mai kahi hōʻailona a kāleka paha. Ma ke ala, ʻae, hiki ke kākau ʻia ka ʻikepili i nā inoa NFC.
- Hoʻololi ma waena o nā mea like. ʻO kēia ka wā e hoʻopili ai ʻoe i nā headphone kelepona i kāu kelepona a hoʻohana paha i ka Android Beam - e hoʻomanaʻo i kēia. Ma laila, ua hana ʻia kahi pilina ma o NFC, a ua lawe ʻia ka hoʻoili ʻana i ka faila ma o Bluetooth.
- Pilikia. Ke hoʻohālike nei kā mākou mea hana i kahi mea passive: kahi kāleka uku a i ʻole kāleka huakaʻi.
No ke aha ʻo NFC inā he Bluetooth a me Wi-Fi, no ka mea, loaʻa iā lākou ka wikiwiki a me ka laulā.
ʻO nā bonus NFC penei:
- Hoʻohui koke - hoʻokahi hapaʻumi o kekona.
- Haʻahaʻa mana hoʻohana - 15 mA. Aia ka Bluetooth i ka 40 mA.
- ʻAʻole pono nā tag i ko lākou mana ponoʻī.
- Aʻaʻole maopopo loa - kahi pōkole pōkole, pono no ka palekana a me ka uku.
Aia pū kekahi Bluetooth Low Energy, akā he moʻolelo ʻokoʻa kēlā.
He aha ke kumu? He aha kēia e hāʻawi ai iā mākou?
Ma kahi o nā hiʻohiʻona i ʻike mua ʻia: nā kaʻa, nā uku a me nā kāleka huakaʻi, aia nā noi e hiki ke kau i ke kālā ma ke kāleka Troika a me nā kāleka halihali ʻē aʻe.
Aia kahi noi - heluhelu kāleka Bank. No ka laʻana, hiki iā ia ke hōʻike i nā kālepa kāleka hou loa. ʻAʻole maopopo iaʻu inā he etika loa kēia, akā aia ka noi ma ka Play Market.
Ma ke ala, makemake nui ka poʻe i ke kumu e hana ʻole ai ʻo Google a me Apple Pay me nā kāleka Mir? ʻAʻole pili i nā hiʻohiʻona ʻenehana. ʻAʻole ʻae wale ka ʻōnaehana uku me nā lawelawe. Hiki iā ʻoe ke uku ma o kāu polokalamu Android - World Pay. Heʻoiaʻiʻo he kaʻa kaʻa, akā ʻaʻole ia e hana me ka iPhone!
Ma ke ala, ola hack. Inā ʻaʻohe NFC o kāu Android, akā makemake maoli ʻoe e uku, he aha kāu e hana ai? Hiki iā ʻoe ke waiho i ke kāleka ma lalo o ka uhi. Kāhea iā mā˚ou. ʻOiaʻiʻo, ʻaʻole hiki i nā hihia mānoanoa ke hoʻouna i nā nalu NFC i kūkulu ʻia - no laila e nānā.
Ua kamaʻilio mua mākou e pili ana i nā hāmeʻa, akā aia kahi lua koʻikoʻi - nā inoa NFC. Hele mai lākou i ʻelua ʻano.
- ʻO nā mea āu e hoʻopaʻa ai i ka ʻike. Ua like lākou me nā kiʻi liʻiliʻi. ʻO ka maʻamau ka hoʻomanaʻo i loaʻa ma kahi o 700 bytes. Ua hana ʻia nā mea like e Sony.
Hiki iā ʻoe ke mālama i kahi hui o nā mea ma aneʻi, no ka laʻana:
- Loaʻa Wi-Fi no nā malihini
- Kākau i kāu ʻike pili a hoʻohana iā ia ma ke kāleka ʻoihana
- E hoʻonoho i kāu kelepona e hele i ke ʻano hiamoe i ka pō ma kāu papa pō
- Hiki iā ʻoe ke mālama i kekahi mau ʻikepili i loko, no ka laʻana he ʻōlelo huna a i ʻole kahi hōʻailona BitCoin. ʻOi aku ka maikaʻi ma ke ʻano hoʻopunipuni.
Hiki ke heluhelu ʻia kēia tag e kekahi kelepona me NFC.
He aha kāu e hana ai inā ʻaʻohe ou mau hōʻailona NFC? Hiki iā ʻoe ke kauoha iā lākou, he mau keneta.
Akā hiki iā ʻoe ke lawe i kahi kāleka panakō maʻamau a i ʻole kāleka halihali, e like me Troika. He mau hōʻailona pilikino kēia. ʻO kahi laʻana maʻamau kāu kāleka panakō. ʻAʻole hiki iā ʻoe ke kākau i kekahi mea ma luna o lākou.
Akā hiki ke hoʻolālā ʻia kāu kelepona e hana i kekahi mea ke hoʻohana ʻia ia mea.
Inā loaʻa iā ʻoe ka Android, hiki iā ʻoe ke hoʻokomo i ka noi no ka laʻana ai ole ia, . I loko o ia mau mea hiki iā ʻoe ke hāʻawi i nā hana like i nā tag NFC. E hoʻohuli i ka Wi-Fi a kāhea aku a hoʻopau, hoʻomaka i nā noi, hoʻāla i ke ʻano pō. No ka laʻana, hiki iā ʻoe ke hana i ka wā e kau ai ʻoe i kāu kelepona ma ke kāleka Troika, kāu . Paipai au!
Ma ke ala, ʻo ia ke ʻano o nā mea o Troika.
Hiki iā ʻoe ke heluhelu ma e pili ana i kahi kanaka i hoʻokomo i kahi hōʻailona NFC ma kona lima.
He aha nā mea ʻē aʻe e hoʻohana ai iā NFC?
ʻO kekahi o nā mea e hoʻohiki ai ʻo nā tiketi uila. I ka hale kiʻiʻoniʻoni a i ʻole i nā ʻahamele. I kēia manawa, hana lākou ma o ka QR code a ʻaʻole maikaʻi loa, i koʻu manaʻo. ʻOiai ʻaʻole e ʻae mai nā miliona o Kina iaʻu.
No Apple
He aha kāu e hana ai inā he iPhone kāu? Manaʻo nā kānaka āpau ua pio ka NFC ma ka iPhone, akā ʻaʻole ʻoiaʻiʻo. E hoʻomaka ana me iOS 11, ʻo ia hoʻi, mai 2017, ua wehe ʻo Apple i ke komo i nā mea hoʻomohala. A ua nui nā noi e like me ka Android. No ka laʻana, NFC Tools.
ʻOiaʻiʻo, aia nō nā palena: ʻo ka lawe ʻana a me nā kāleka kāleka, no ka laʻana, ʻaʻole hiki ke nānā ʻia. Pono mākou i nā hōʻailona kūikawā, a mākou i kūkākūkā mua ai.
He aha ka hana? Hoʻokomo ʻo iOS 13 i ka hiʻohiʻona Commands (Siri). A i kēia manawa hiki iā ia ke komo i nā hōʻailona NFC. No laila hiki iā ʻoe ke hoʻonohonoho i ka hoʻomaka ʻana o ke mele me ka hoʻohana ʻana i ke kāleka Troika. A i ʻole e hoʻā i kahi ʻōpuʻu kukui akamai. A i ʻole he hui o nā mea ʻē aʻe. ʻO nā hui he mea pōma maoli. ʻAʻole maopopo iaʻu ke kumu i loaʻa ʻole ai iā Android kēia.
Kālena
Inā ma kēia manawa ua hoʻoholo ʻoe ua ʻike ʻoe i nā mea āpau e pili ana i ka NFC a ua luhi ʻoe i kēia mau noi lohi. No laila, eia kekahi mea pumehana iā ʻoe.
Aia kekahi hui i kapa ʻia ʻo NFC Forum e hōʻoia i ka NFC. Ma keʻano laulā, aia kēlā me kēia ʻenehana i kahi hui, a maikaʻi inā hoʻokahi wale nō.
A i kekahi lā aʻe ua hoʻokuʻu lākou i kahi mea hou i ka maʻamau. A manaʻo he aha? Kākoʻo ʻo NFC i ka hoʻouka uila. ʻAe, ʻoiaʻiʻo, ʻo kēia ka hā o ke ʻano hana.
He aha kāu e nīnau ai? Electromagnetic induction, e hoʻomanaʻo? Me kona kokua.
Ma ke ala, hana pololei ʻo Qi charging ma ke kumu like. Aia wale nō kahi wili nui.
Akā hoʻokahi pilikia. He liʻiliʻi ka coil NFC, ʻo ia hoʻi ka haʻahaʻa o ka mana hoʻopiʻi - 1 Watt wale nō.
Hiki paha ke hoʻopaʻa i ke kelepona i kēia wikiwiki? Mai ho'āʻo. Akā naʻe, ʻaʻole i hana ʻia kahi hana no kēia.
ʻO ke kumu nui ka ʻokoʻa - ka hoʻouka ʻana i nā polokalamu ʻē aʻe me kahi kelepona. Ua like kēia me ka hoʻihoʻi ʻana i ka Galaxy a me nā kelepona ʻē aʻe. No ka laʻana, hiki iā ʻoe ke mana i nā headphone kelepona iā lākou iho, ʻaʻole ka hihia mai lākou. ʻO ka mea nui, loaʻa iā mākou kahi kelepona uʻi liʻiliʻi loa i loaʻa i kekahi kelepona a hiki ke hoʻokomo maʻalahi i loko o kekahi mea akamai.
Ma ke ala, ʻaʻole liʻiliʻi ka 1 Watt. No ka hoʻohālikelike ʻana, hoʻohana nā iPhones āpau koe ka 11 Pro i kahi charger 5-watt. A ʻo ka mana o ka hoʻihoʻi ʻana i ke kelepona ʻole i nā hae hae hou e loli ana ma kahi o 5 a i ʻole 7 W.
Akā hoʻokahi mea - ʻaʻole e hana kēia hiʻohiʻona i nā hiʻohiʻona o kēia manawa. ʻO nā smartphones me kēlāʻano hiʻohiʻona e hoʻomaka paha eʻikeʻia i loko o hoʻokahi makahiki a me ka hapa. No laila e makaʻala no ka hoʻolaha ʻana o Samsung i kēia mea.
Bonus no ka poʻe i pau ka heluhelu ʻana
Ua ʻike mākou makemake ʻoe i kā mākou mau kikoʻī kikoʻī, akā maopopo mākou he manaʻo kou no ia mau wikiō, a he palapala mākaukau paha. No laila, inā he manaʻo kāu, maopopo iā ʻoe ke kumuhana a mākaukau e hana i kahi loiloi me mākou - e kākau i kā mākou leka uila hou [pale ʻia ka leka uila]. E hana mākou i wikiō maikaʻi loa!
