I-NFC efonini yikhokhnoloji yokuxhumana engenazintambo ezingenazintambo nge-radius encane yomthelela evumela ukuthi ukhulume ngaphandle kolwazi phakathi kwamagadget amabili. I-NFC isekelwe ku-RFID, lokhu kuqashelwa kwemvamisa yomsakazo, okuyinto indlela yokulungisa ngokuzenzakalelayo into.
Kuyini "i-NFC"?
I-NFC iyinhlangano yobuchwepheshe ngaphandle kokuxhumana, ekwazi ukufunda nokuthumela ulwazi kusuka kumadivayisi kumabanga akude kakhulu. Isifinyezo sisho "Ukuxhumana Okuseduze kweFild". Isekelwe esimisweni sokushintshaniswa kwempawu zomsakazo ezifanayo noBlutuz, kodwa kukhona umehluko omkhulu. I-Bluetooth idlulisa idatha kumabanga amade, amamitha angamakhulu ambalwa, futhi i-NFC ayithathi engaphezu kwamamentimitha angu-10. Lolu buchwepheshe lwakhiwe njengesandiso samakhadi angenalwazi, kodwa ngokushesha wathola udumo, futhi abathuthukisi bakutholile lisetshenziswe kwamanye amadivayisi.
Kunezindlela ezintathu zokusebenzisa lobu buchwepheshe kumakhalekhukhwini:
- Imodi yokufunda;
- ukulingisa, lapho idivayisi isebenza, njengekhadi lokukhokha noma idlule;
- Imodi ye-P2P, uma ulwazi lushintshaniswa phakathi kwamafoni.
I-chip igcinwe efonini, futhi isetshenziswa njengendlela yokukhokha, kungenzeka ukubhuka amathikithi, ukukhokhela imoto yokupaka noma ukuhamba ukuya emgwaqweni, futhi uqinisekise ukulawulwa kokungena. Ngenxa yezinqubo zezobuchwepheshe zokukhokha ngaphandle kokuxhumana, amakhadi we-MasterCard PayPass neVisa PayWave ane-antenna ahlanganisiwe avele, acabangela indima ye-NFC, izinhlelo zokusebenza ezithuthukisiwe ze-smartphone-smartphones.
Kuyini i-NFC ku-smartphone? Ngokuxhumana okusheshayo, amadivaysi ambalwa axhumeke ngokufakelwa kwe-magnetic field, lapho ama-antenna e-close axhumana naye eseduze enza ifisha. Ngaphansi kwesenzo se-NFC, ama-frequencies avela ku-13.56 Megahertz abelwe, futhi izinga lokudluliswa kolwazi likwazi ukufinyelela ezingamakhilomitha angu-400 ngomzuzwana. Idivayisi isebenza ngezindlela ezimbili:
- Isebenza . Zombili izigaja zinikwe umthombo wamandla futhi zithumelele ulwazi.
- I-Passive . Amandla endle womunye wamadivayisi asetshenzisiwe.
Yiziphi amafoni anayo i-NFC?
I-NFC efonini inikeza ithuba lokukhokha ukuthenga ngokuthinta umakhalekhukhwini ku-terminal, lena uhlobo lwekhadi lebhange esitokisini. Eminyakeni eyisithupha edlule, kwakukhona amadivayisi ambalwa asekela i-NFC, kodwa manje ama-chips afakwe amaphilisi, amawashi namanye amadivayisi. Yiziphi amafoni anale divayisi:
- Apple - zonke izinhlobo ze-iPhones;
- U-Sony-umyalelo we-Xperia S, L, Z;
- I-Samsung Galaxy S;
- I-HTC #
- I-LG;
- I-Motorola;
- I-Nokia-Lumia.
Ngingazi kanjani ukuthi ifoni isekela i-NFC?
Indlela yokuhlola i-NFC, ingabe ifoni? Kunezindlela eziningana:
- Susa ikhava yangemuva ye-smartphone bese uhlola ibhethri yebhethri, kufanele ibhalwe "i-NFC".
- Kulezi zilungiselelo, thola ithebhu ye- "Wireless Networks", chofoza ku- "Ngaphezu", uma ubuchwepheshe bukhona, umugqa uvela negama lobuchwepheshe.
- Bamba isandla sakho phezu kwesikrini, vula ikhethini lezaziso, lapho le nketho izobhaliswe khona.
Uma kungekho NFC, yini okufanele ngiyenze?
I-NFC efonini - yiziphi lezi modules? Kunezinhlobo ezinjalo eziyisisekelo:
- ama-sim amakhadi;
- Amadivayisi angaphandle;
- microcircuits;
- Amamodeli we-NFC;
- izitika.
Umthamo we-NFC ungathengwa kanye namafoni, kodwa athengiswa futhi ngokwehlukana. Izitika zinamathele egodini, ziza izinhlobo ezimbili:
- Isebenza. Nikeza ukuxhumana nge-Wi-Fi / Bluetooth isiteshi, kodwa udle amandla amaningi, ukuvuselelwa njalo njalo kuyadingeka.
- I-Passive. Ungathintani nefoni futhi ungayibhali kudivayisi ngokusebenzisa iziteshi zokuxhumana zamaselula.
Indlela yokufaka i-NFC-chip efonini?
Uma kungenjalo ekuqaleni kwedivayisi, umthamo we-NFC wefoni ungathengwa futhi ufakwe. Kunezinketho ezimbili ongakhetha kuzo:
- I-NFC-simka, manje ithengiswa yizinkampani eziningi zeselula.
- I-antenna ye-NFC. Uma kungekho nsimu eduzane, lena yindlela engcono kakhulu yokuphuma. Emasilons of communication, amadivaysi anjalo akhona, ahlanganiswe ekhadini le-SIM, ngaphansi kwendwangu yeselula. Kodwa kunesici esisodwa: uma ikhava yangemuva ingasusiwe noma umgodi we-sim khadi uhlangothi, awukwazi ukufaka i-antenna enjalo
Ungamnika amandla kanjani i-NFC?
Idivaysi ene-NFC ayikwazi nje kuphela isikhwama semali esikhwameni, ukuhamba kanye nesaphulelo, amathegi akhethekile futhi asiza ukufunda idatha mayelana nezimpahla ezitolo, mayelana nanoma yiziphi izinto kumamyuziyamu namakamelo. Ivuleka kanjani?
- Kulezi zilungiselelo, khetha "Amanethiwekhi angenantambo", bese - "Ngaphezu".
- Ukubhaliswa okudingekayo kuzovela, makabe "Yenza kusebenze".
Uma i-smartphone yakho inesiphakamiso se-NFC, kuzomele usebenze i-Android Beam:
- Kuzilungiselelo, chofoza ithebhu Okuthuthukisiwe.
Chofoza ku-NFC-switch, umsebenzi we-Android usebenza ngokuzenzakalelayo. Uma lokhu kungenzeki, udinga ukuchofoza ithebhu ye- "Android Beam" bese ukhetha "vumela".
- Ukuze ukhulume nakanjani, udinga ukuqinisekisa ukuthi womabili amafoni asekela i-NFC ne-Android Beam, udinga ukuwaqalisa kuqala. Uhlelo lwezenzo lulandelayo:
- Khetha ifayela lokudlulisa.
- Cindezela izingqwembe zangemva kwamafoni ndawonye.
- Bamba idivayisi kuze kube yi-beep eqinisekisa ukuthi ukushintshaniswa sekuphelile.
Kungakhathaliseki uhlobo lwefayela, ubuchwepheshe be-NFC buyathatha i-algorithm yokudlulisa imininingwane elandelayo:
- Gcina idivaysi kuphela uhlangothi oluphikisanayo komunye nomunye.
- Linda aze athole omunye nomunye.
- Qinisekisa isicelo sokudlulisa.
- Lindela umyalezo wokuthi inqubo iphelile.
Izici ze-NFC
Umsebenzi we-NFC kugajethi ikunika izinzuzo ezinkulu:
- ukuthinta kweselula - nedatha edluliselwe;
- Uhlu olubanzi lwezicelo;
- ubuchwepheshe buhlangana namazinga omkhakha;
- Ukusebenza kwe-transmitter ephansi kanye nengqikithi yokuchayeka kudinga ukuthunyelwa okuphephile.
I-NFC efonini noma kwamanye amadivaysi - into elula kakhulu okudingeka ukwazi ngayo isicelo esifanele sale divayisi?
- Izesekeli ze-Bluetooth nazo zisekela i-NFC, isibonelo esisodwa ikholomu ye-Nokia Play 360.
- Ukwenza isikhwama semoto eselula, kufanele ufake futhi ulungise uhlelo lokusebenza lwe-Google Wallet.
- Ama-NFC-tags avunyelwe ukuthi asetshenziselwe ukuhlela ngokusebenzisa izinhlelo zokusebenza, angenza kusebenze isistimu ye-navigator, ukudlulisela iselula kwimodi ethule futhi ngisho newashi iwashi.
- Ngokusebenzisa i-NFC, kulula ukudlulisela inkokhelo kumngani, yenza umngane, futhi ngisho ngokuhlanganyela uhlanganyele emdlalweni ngenani elikhulu labasebenzisi.
