I-NFC ubuchwepheshe bokuxhumana obungenazintambo bebanga elifushane.Lobu buchwepheshe buvele kokuthi i-non-contact radio frequency identification (RFID) futhi bathuthukiswa ngokuhlanganyela yi-Philips Semiconductors (manje eyi-NXP Semiconductors), i-Nokia kanye ne-Sony, ngokusekelwe ku-RFID kanye nobuchwepheshe be-interconnect.
I-Near Field Communication iwubuchwepheshe berediyo yebanga elifushane, imvamisa ephezulu esebenza ebangeni lamasentimitha ayi-10 ku-13.56MHz.Ijubane lokudlulisa ngu-106Kbit/sec, 212Kbit/sec noma 424Kbit/sec.
I-NFC ihlanganisa imisebenzi yomfundi ongathinteki, ikhadi lokungathinteki kanye ne-peer to-peer ku-chip eyodwa, ivumela ukuhlonza nokushintshaniswa kwedatha ngamadivayisi ahambisanayo ahamba amabanga amafushane.I-NFC inezindlela ezintathu zokusebenza: imodi esebenzayo, imodi yokwenziwa kanye nemodi yokukhomba kabili.
1. Imodi esebenzayo: Kumodi esebenzayo, uma idivayisi ngayinye ifuna ukuthumela idatha kwenye idivaysi, kufanele ikhiqize indawo yayo yamafrikhwensi omsakazo, futhi kokubili idivaysi eqalisayo nocingo oluqondiswe kuyo kufanele yenze eyazo inkundla yokuxhumana.Lena imodi ejwayelekile yokuxhumana kontanga futhi ivumela ukusethwa koxhumano olushesha kakhulu.
2. Imodi yokuxhumana yokwenziwayo: Imodi yokuxhumana yokwenziwa iphambene nemodi esebenzayo.Ngalesi sikhathi, itheminali ye-NFC ilingisa njengekhadi, eliphendula ngokungenzi lutho endaweni yefrikhwensi yomsakazo ethunyelwa ngamanye amadivaysi futhi lifunde/libhale ulwazi.
3. Imodi yezindlela ezimbili: Kule modi, izinhlangothi zombili zetheminali ye-NFC ngokukhuthele zithumela inkundla yefrikhwensi yomsakazo ukuze kutholwe ukuxhumana kwephoyinti nephuzu.Ilingana nawo womabili amadivayisi e-NFC akumodi esebenzayo.
I-NFC, njengobuchwepheshe obudumile bokuxhumana basensimini eminyakeni yamuva nje, isetshenziswa kabanzi.Izinhlelo zokusebenza ze-NFC zingahlukaniswa cishe zibe izinhlobo ezintathu eziyisisekelo ezilandelayo
1. Inkokhelo
Isicelo sokukhokha se-NFC ikakhulukazi sibhekisa ekusetshenzisweni kwefoni ephathekayo enomsebenzi we-NFC ukulingisa ikhadi lasebhange, ikhadi nokunye.Uhlelo lokusebenza lokukhokha lwe-NFC lungahlukaniswa izingxenye ezimbili: uhlelo lokusebenza oluvulekile kanye nohlelo lokusebenza oluvaliwe.Ukusetshenziswa kwe-NFC okwenziwe ngokoqobo ekhadini lasebhange kubizwa ngokuthi i-open-loop application.Ngokufanelekile, iselula enomsebenzi we-NFC kanye nokwengeza ikhadi lasebhange le-analog ingasetshenziswa njengekhadi lasebhange ukuswayipha umakhalekhukhwini emishinini ye-POS ezitolo ezinkulu nasezinxanxatheleni zezitolo.Kodwa-ke, ngenxa yokuduma kwe-Alipay ne-WeChat e-China, ingxenye yangempela ye-NFC ezicelweni zokukhokha zasekhaya incane uma kuqhathaniswa, futhi ixhumeke kakhulu futhi ihlanganiswe ne-Alipay ne-WeChat Pay njengendlela yokusiza i-Alipay ne-WeChat Pay ukuze kuqinisekiswe ubuwena. .
Ukusetshenziswa kwe-NFC kulingisa ikhadi lekhadi elilodwa kubizwa ngokuthi i-closed-loop application.Njengamanje, ukuthuthukiswa kwezinhlelo zokusebenza ze-NFC ezivaliwe e-China akulungile.Nakuba uhlelo lwezokuthutha zomphakathi kwamanye amadolobha luvule umsebenzi we-NFC womakhalekhukhwini, alukasakazwa.Nakuba ezinye izinkampani zamaselula ziye zahlola umsebenzi wekhadi lebhasi le-NFC lomakhalekhukhwini kwamanye amadolobha, ngokuvamile kudingeka zenze kusebenze izimali zesevisi.Kodwa-ke, kukholakala ukuthi ngokuthandwa kwezingcingo eziphathwayo ze-NFC kanye nokuvuthwa okuqhubekayo kobuchwepheshe be-NFC, uhlelo lwekhadi elilodwa luzosekela kancane kancane ukusetshenziswa komakhalekhukhwini be-NFC, futhi uhlelo lokusebenza oluvaliwe luzoba nekusasa eliqhakazile.
2. Isicelo sokuphepha
Ukusetshenziswa kokuphepha kwe-NFC ikakhulukazi ukwenza omakhalekhukhwini babe amakhadi okulawula ukufinyelela, amathikithi e-elekthronikhi, njll. Ikhadi lokulawula ukufinyelela okubonakalayo le-NFC ukubhala idatha yekhadi lokulawula ukufinyelela elikhona ku-NFC yocingo oluphathwayo, ukuze umsebenzi wokulawula ukufinyelela. kungenziwa ngokusebenzisa iselula ene-NFC function block ngaphandle kokusebenzisa i-smart card.Ukusetshenziswa kwethikithi le-elektroniki le-NFC ukuthi ngemva kokuba umsebenzisi ethenge ithikithi, uhlelo lokuthenga amathikithi luthumela ulwazi lwethikithi kumakhalekhukhwini.Iselula enomsebenzi we-NFC ingakwazi ukwenza ulwazi lwethikithi lube ithikithi le-elekthronikhi, futhi umakhalekhukhwini ungaswayipha ngokuqondile ekuhloleni ithikithi.Ukusetshenziswa kwe-NFC ohlelweni lwezokuphepha kuyinkambu ebalulekile yohlelo lokusebenza lwe-NFC esikhathini esizayo, futhi ithemba libanzi kakhulu.Ukusetshenziswa kwe-NFC kulo mkhakha akukwazi nje ukusindisa izindleko zabaqhubi, kodwa futhi kuletha lula okuningi kubasebenzisi.Ukusebenzisa omakhalekhukhwini ukufaka esikhundleni samakhadi okulawula ukufinyelela ngokomzimba noma amathikithi ekhadi kazibuthe kunganciphisa izindleko zokukhiqiza kokubili ngokwezinga elithile, futhi ngesikhathi esifanayo kusize abasebenzisi ukuvula nokuswayipha amakhadi, kuthuthukise izinga lokuzenzakalela ngokwezinga elithile, kunciphise izindleko zokuqasha izisebenzi ezikhipha amakhadi kanye nokuthuthukisa ukusebenza kahle kwesevisi.
3. Uhlelo lokusebenza lomaka we-NFC
Ukusetshenziswa kwethegi ye-NFC ukubhala ulwazi oluthile kumaki we-NFC, futhi umsebenzisi angathola ngokushesha ulwazi olufanele ngokuswayipha nje umaka we-NFC ngomakhalekhukhwini we-NFC.Isibonelo, abathengisi bangabeka omaka be-NFC abaqukethe amaphosta, ulwazi lokuphromotha, nezikhangiso emnyango wesitolo.Abasebenzisi bangasebenzisa omakhalekhukhwini be-NFC ukuze bathole ulwazi olufanele ngokwezidingo zabo, futhi bangangena ezinkundleni zokuxhumana ukuze babelane ngemininingwane noma izinto ezinhle nabangane.Njengamanje, amathegi e-NFC asetshenziswa kakhulu emakhadini okuhambela isikhathi, amakhadi okulawula ukufinyelela namakhadi ebhasi, njll., futhi ulwazi lwethegi ye-NFC luyahlonzwa futhi lufundwe ngedivayisi yokufunda ye-NFC ekhethekile.
I-handheld-wirelessibigxile ekuthuthukisweni nasekukhiqizweni kwamadivayisi e-IoT asuselwa kubuchwepheshe be-RFID iminyaka eminingi, ihlinzeka amakhasimende ngemikhiqizo nezinsizakalo ezenziwe ngokwezifiso kubandakanyaImishini yokufunda nokubhala ye-RFID, NFC handsets,izikena zebhakhodi, izinto eziphathwayo zebhayomethrikhi, omaka be-elekthronikhi nesofthiwe yohlelo lokusebenza ehlobene.
