Ndi munthu wotani yemwe akufunikira kudziwa za Near Field Communications
Kuyankhulana Kwadongosolo (NFC) ndi teknoloji yopanda waya yopangidwa ndi makina osagwiritsa ntchito makina okonzedwa kuti athe kuyankhulana pakati pa zipangizo ziwiri. Kuyankhulana Kwapafupi Kapena NFC yapangidwa kuti iyankhule pamtunda wapafupi kwambiri. NFC inali mu nyuzipepala mu 2014 chifukwa cha mphekesera kuti apulogalamuyi idzakhala ndikuphatikizapo luso lamakono mu kumasulidwa kwa iPhone. Google ikuphatikizapo zamakono mu Android ndi Samsung zakhala zikuphatikiziranso zina mwa mafakitale awo.
Tangoganizirani CEO kuchokera kwa kampani yanu imalowa mu elevator yanu pafupi ndi kutseka. Amati, "Hayi Jimmy, ndikuwerenga za NFC pa imodzi mwazomwe ndimazikonda kwambiri zaminyanga zamakono." Zinthu zoyamba poyamba. Musawope. Popeza ndinu wowerenga nthawi zonse za gawo lino, mwakonzekera "mawu okwera" pafupi ndi Field Communications. Mawu okwera kapena zowonjezera zowonjezera zowonekera pazomwe muli nazo mukakhala ndi mphindi zochepa kuti mufotokoze kapena kuyikapo kanthu kwa mkulu. Lingaliro ndiloti mawu okweza ndiwongophunzitsidwa. Nthawiyi ndi yofunika kwambiri chifukwa muli ndi kutalika kwa ulendo wokwera kuti mupange zonsezi. Tiyeni titenge mawu anu okweza okonzekera ku Near Field Communication kapena NFC.
Pafupi Kulumikizana Kwambiri (NFC) - A Primer
Kuyankhulana Kwadongosolo (NFC) ndi makina osagwira ntchito omwe amagwira ntchito pafupifupi masentimita 4. Ganizirani za kutsegula iPhone yanu pafupi ndi wowerenga kirediti kongoti ku chipani cha Chipotle.
NFC yakhazikitsidwa payeso yolumikizana yomwe imatanthawuza momwe zipangizo ziwiri zimakhazikitsira anzanu pa intaneti pofuna kusinthanitsa deta. NFC imagwiritsa ntchito magetsi opanga magetsi kuti alankhule. Izi ndi zosiyana ndi Bluetooth kapena Wi-Fi zomwe zimagwiritsa ntchito mauthenga a wailesi. Komabe, NFC ikugwirizana ndi matekinoloje onse.
Icho ndi chitetezo mwachibadwa pamene chofunikira cha mtunda chiri pafupi kwambiri. Konzekerani kukondweretsa Mtsogoleri Wanu ndi deta ina:
- UFC ikugwira ntchito pa 13.56 MHz ndipo ili ndi kuwerenga ndi kulemba njira ya 2013.
- UFC imasuntha pa mlingo mpaka 424 Kbits / wachiwiri.
- UFC imagwiritsa ntchito zikhalidwe kuchokera ku ISO, ECMA, ndi ETSI.
Kuyankhulana Kwapakati Pafupi (NFC) - Mbiri
Sony ndi Phillips akutsogolera akatswiri a NFC masiku ano, koma chiyambi cha waya opanda waya chimabwerera kumapeto kwa chaka cha 2003, pamene chinavomerezedwa ngati chiwerengero cha ISO / IEC. Mu 2004, Nokia, Sony, ndi Phillips anapanga NFC Forum, yomwe ili ndi mamembala oposa 200 kuphatikizapo opanga, opanga, komanso mabungwe a zamalonda lero.
Mu 2006, bungwe la NFC linalemba lusoli ndikupanga mapu oyambirira. Mayesero angapo a teknoloji anachitika mu 2007 ndi 2008, koma sizinachoke chifukwa cha kusowa thandizo kwa ogwira ntchito ndi mabanki. NFC yatsala pang'ono kutha, monga opanga mafakitale akuluakulu akuphatikizirapo zipangizo zamakono. Kuyambira mu 2011, chitukuko cha NFC chinali chofala ku Asia, Japan, ndi Europe. Komabe US akuyamba kugwira.
Kuyankhulana Kwapafupi (NFC) - Mapulogalamu
Mapulogalamu a NFC akuwonetseratu. Nazi zochitika zingapo:
- Mafoni awiri a NFC akhoza kusinthanitsa deta pokhapokha ndikuwatsata kapena kuwabweretsa pamodzi.
- Chipangizo cha kamera cha NFC chikhoza kutumiza zithunzi ku kompyutayi yokonzekera NFC kapena HDTV.
- NFC yokonza makompyuta ikhoza kusamutsa deta ku foni.
- Kugwiritsira ntchito chipangizo cha m'manja cha NFC kuti muwone ndikulipira pa zolembera za ndalama - chikwama chapafupi.
- Kugwiritsa ntchito zipangizo zamakono za NFC kuti zogula kuchokera ku makina osungira katundu.
- Chipangizo cha mobile NFC chikhoza kulipira mita yosungirako magalimoto.
- Chipangizo cha mobile NFC chingathe kupeza ndalama kuchokera ku ATM.
- Kugwiritsira ntchito chipangizo cha foni ya NFC ya mapulogalamu okhwima.
Near Field Communications (NFC) - The Technology
Sayansi ya Near Field Communication ikukondweretsa kwambiri.
NFC imagwira ntchito m'njira ziwiri.
- Machitidwe Ogwira Ntchito - Mwachikhalidwe ichi, zipangizo zonsezi zikupanga RF masamba awo. Izi zikhoza kukhala ngati zipangizo ziwiri zamagetsi zikugwiritsidwa ntchito kusinthanitsa deta.
- Zochita - Njira Yopanda Pakati : Mwa njira iyi, imodzi mwa zipangizozi zimapanga munda wa RF ndipo chipangizo china chimagwiritsa ntchito mundawo kuti ukhale wamphamvu ndi kulankhulana. Chipangizo chogwiritsira ntchito nthawi zambiri chimakhala "wowerenga" ndipo chipangizo choperekera ndi "tag".
Chipangizo chogwira ntchito kapena wowerenga nthawi zambiri amafufuzira pazipangizo zapafupi za NFC. Chida kapena chida choyambira chimayamba kumvetsera pakakhala masentimita angapo a chipangizo cha NFC chogwira ntchito. Owerenga amatha kulankhulana ndi chizindikiro kuti adziwe njira zamakono zomwe zingagwiritsidwe ntchito. Pakali pano, pali matekinoloje atatu owonetsera:
- NFC-A, yomwe ili RFID mtundu A
- NFC-B, yomwe ili RFID mtundu B
- NFC-F, yomwe ndi FeliCA
Mukamaliza kugwiritsira ntchito chipangizo chomwe chiyenera kugwiritsidwa ntchito, owerenga adzaika chiyanjano choyankhulana ndi magawo onse oyenera. Malemba ena amalembedwa kuti owerenga athe kusinthira deta. Ganizirani za khadi la ngongole lovomerezeka la NFC. Khadi la ngongole likhoza kudutsa pamtengowu monga nambala ya khadi la ngongole kapena tsiku lomaliza.
NFC yothandizira foni ikhoza kugwira ntchito mwachangu. Monga njira yolipira kuntchito yogulitsa malonda, NFC yokonzekera foni idzachitapo kanthu mwachitsulo ndi zipangizo zomwe zili pa siteshoni yowonongeka yomwe ikugwira ntchito. Mu ntchito ina, foni yamakono ya NFC ikhoza kugwiritsidwa ntchito polemba chizindikiro pa phukusi kuti mupeze tsatanetsatane wa deta za zomwe zili.
Pankhaniyi, foni ikugwira ntchito yogwira ntchito.
Chinthu chodziwikiratu kuti apange chipangizo chamakono cha NFC ndicho chilengedwe cha NFC chophatikizidwa. Chifukwa cha NFC kukhala mu nyuzipepala posachedwa ndi chiwerengero chowonjezeka cha opanga makampani kuphatikizapo chips ichi mu mafoni awo. Poyankha, msika uyenera kutulutsa mtengo wotsika mtengo, malonda odziimira okhazikitsa NFC kuti msika ukule. Mmodzi mwa akatswiri opanga malonda a sayansiyi ndi Innovision Research & Technology yochokera ku UK, yomwe inagulidwa ndi Broadcom Corporation. Onani zofalitsa za Broadcom pazokambirana za NFC.
Pafupi kulankhulana kwapakati (NFC) - Security
Chofunikira chachikulu cha chitetezo ndi chakuti zida ziwiri ziyenera kukhala pafupi kwambiri ndi ntchito. Deta pakati pa zida ziwiri za NFC zogwirizanitsa zikhoza kulembedwa pogwiritsa ntchito miyezo ya AES. Kuyimitsa mawu sikofunikira ndi muyezo, koma ndithudi kukhala njira yabwino kwambiri. Kulephera kutsekedwa kwachinsinsi kunali mwachangu kuti zitsimikizidwe kuti zipangizo zamakono zogwirizana ndi zomwe RFID zinayambitsa.
Kudya chakudya ndi chinthu chodetsa nkhaŵa mwa chitetezo. Zopeka, chipangizo chachitatu chingalowe mu chithunzi ndikuba deta. Ichi ndichifukwa chake kufotokozera kungakhale kofunikira pa zinthu monga kugulitsa ngongole.
Zikanakhala kuti chipangizo chokonzekera cha NFC chikubedwa, pali ngozi kuti khadi la ngongole lingagwiritsidwe ntchito kugula. Zochitika za chipangizo chogwiritsira ntchito chachinsinsi cha NFC chobedwa chingadzitetezedwe pogwiritsira ntchito passcode kapena password kuti mutsirizitse kuyankhulana.
Ofufuza akuyang'ana njira zothetsera chitetezo m'makhadi a ngongole ndi zipangizo zina zopanda pake. Ponena za kugwirizana kotetezeka pakati pa zipangizo ziwiri zothandizira NFC, kufotokozera ndi njira yabwino kwambiri yotetezera mtsinje wolumikizana.
NFC Elevator Statement
Tsono tsopano kuti mudziwe zambiri zokhudza Kuyankhulana Kwapafupi kuti mukakwera pa elevator ndi CEO wanu ndikumufotokozereni, apa tikupita.
CEO:
Hemani Jimmy. Ndinkangowerenga za NFC pa imodzi mwa mapepala omwe ndinkakonda kwambiri mapulogalamu a njovu. Kodi ntchito imeneyo, bwanji "?
Munthu WAKE:
Near Field Communications ndizochititsa chidwi kwambiri ndipo zidzapitiriza kukula. Mukudziwa kuti ma chips akuphatikizidwa mu ma iPhones atsopano omwe amalola NFC kugwira ntchito ndikuyendetsa galimoto. Ngakhale kuti luso lamakono likufala ku Japan ndi ku Ulaya mu 2011, a US anachedwa kulandira. Ngakhale, teknoloji imalola kulankhulana kophweka pakati pa zipangizo ziwiri zothandizira NFC. Chimodzi mwa zipangizochi chingakhale kachipangizo kokha monga chizindikiro chokhala ndi teknoloji ya NFC. IPhone yanu ikhoza kusunga deta kuchokera pa laputopu yanu, kugula chakudya chamasana, kapena ngakhale kuyang'ana zamalonda zathu zowonjezera mwa kuyimitsa pafupi ndi tags yokonzekera ya NFC kapena chipangizo. Tangoganizirani zomwe timagulitsa ndi NFC ndipo makasitomala athu akhoza kuyendetsa iPhone yawo pafupi ndi chizindikiro cha NFC ndikupeza zinthu zamtengo wapatali. Mukuganiza chiyani? Kodi tiyenera kuchita umboni?
