Yeka ukuthi umuntu we-IT udinga ukwazi kanjani mayelana ne-Near Field Communications
Ukuxhumana Okuseduze Kwendawo (NFC) ubuchwepheshe obungenawaya be-electromagnetic eklanyelwe ukuxhumana phakathi kwamadivayisi amabili. Ukuxhumana Okuseduze Kwendawo noma i-NFC yakhelwe ukuxhumana ngokuhamba okude kakhulu. I-NFC yayisezindaba ngo-2014 ngenxa yamahemuhemu ukuthi i-Apple izofaka ubuchwepheshe ekukhululweni okulandelayo kwe-iPhone. I-Google ifaka ubuchwepheshe ku- Android nakwa-Samsung bufake phakathi kwezinye izingcingo zabo.
Ake ucabange ukuthi i-CEO evela enkampanini yakho igxumela ku-elevator yakho njengoba sekuzovalwa. Uthi, "Sawubona uJimmy. Ngangifunda nge-NFC kwelinye lamabhulogu wami wezintandokazi zendlovukazi yami eyintandokazi. Izinto zokuqala kuqala. Ungesabi. Njengoba ungumfundi ovamile walesi sigaba, ulungiselele "isitatimende se-elevator" mayelana ne-Near Field Communications. Isitatimende se-elevator noma imiphumela yokukhuluma ye-elevator kusukela esimweni lapho unemizuzu embalwa ukuchaza noma ukufaka okuthile ku-executive. Umqondo wukuthi isitatimende se-elevator sichazwa ngokunye. Isikhathi sibucayi ngoba unalo kuphela ubude bokugibela i-elevator ukumboza konke. Ake sithole isitatimende sakho se-elevator silungele ukuxhumana kwe-Near Field noma i-NFC.
I-Field Communications Communications (I-NFC) - I-Primer
Ukuxhumana Okuseduze Kwendawo (i-NFC) ubuchwepheshe obungenakuxhumana obungasebenzisa ububanzi obungaba ngu-4 centimitha. Cabanga ngokusindisa i-iPhone yakho eduze nomfundi wekhadi lesikweletu kumaphikisi we-Chipotle.
I-NFC isekelwe esimisweni sokuxhumana esichaza indlela amadivaysi amabili akha ngayo inontanga kwinethiwekhi yontanga ukuze atshintshane idatha. I-NFC isebenzisa amasimu omsakazo we-electromagnetic ukuxhumana. Lokhu kuqhathaniswa ne- Bluetooth noma i- Wi-Fi esebenzisa ukuthunyelwa komsakazo. Noma kunjalo, i-NFC iyahambisana nobuchwepheshe bombili.
Iphephile ngokwemvelo njengoba isidingo esiseduze sesiseduze kakhulu. Lungele ukugcizelela i-CEO yakho ngenye idatha:
- I-UFC isebenza ku-13.56 MHz futhi inemodi yokufunda nokubhala kusukela ngo-2013.
- I-UFC idluliselwa ngesilinganiso kufika ku-424 Kbits / yesibili.
- I-UFC isebenzisa amazinga avela ku-ISO, i-ECMA, ne-ETSI.
Ukuxhumana Okuseduze Kwendawo (NFC) - Umlando
U-Sony no-Phillips bahola abashayeli be-NFC namuhla, kodwa umsuka wezinga elingenazintambo libuyela emuva ngasekupheleni kuka-2003, lapho livunyiwe njengezinga le-ISO / IEC. Ngo-2004, i-Nokia, i-Sony, ne-Phillips yakha iForamu ye-NFC, enamalungu angaphezu kuka-200 kubandakanya abakhiqizi, abathuthukisi, nezinhlangano zezinsizakalo zezimali namuhla.
Ngo-2006, iNkundla ye-NFC yabhala ubuchwepheshe futhi yakha ibalazwe layo lokuqala. Izilinganiso eziningana zobuchwepheshe zenzeke ngo-2007 no-2008, kodwa azizange zithathwe ngempela ngenxa yokungabi nesekelo ngabathwali namabhange. I-NFC ilungele ukuphuma, njengoba abakhiqizi abakhulu bezelula bafaka ubuchwepheshe kwimikhiqizo yabo. Kusukela ngo-2011, ubuchwepheshe be-NFC buvame kakhulu e-Asia, eJapane naseYurophu. Kodwa-ke i-US iqala ukubamba.
Ukuxhumana Okuseduze Kwendawo (NFC) - Izicelo
Izicelo ze-NFC zibonakaliswa. Nazi izimo ezimbalwa:
- Amafoni amabili e-NFC angashintshanisa idatha ngokubamba nje noma ukuwahlanganisa.
- Idivayisi yekhamera ye-NFC ingadlulisela izithombe kwi-NFC ikhompyutha ehlomele noma i-HDTV.
- I-NFC ikhompyutha ehlomekayo ingadlulisela idatha kudivayisi yeselula.
- Ukusebenzisa idivayisi ye-NFC yeselula ukuhlola bese ukhokhela irejista yemali - isikhwama esincane.
- Ukusebenzisa amadivayisi weselula we-NFC ukwenza ukuthenga kwimishini yokuthengisa.
- Idivayisi yeselula ye-NFC ingakhokha imitha yokupaka.
- Idivaysi yeselula ye-NFC ingafinyelela imali kusuka ku-ATM.
- Ukusebenzisa idivayisi yeselula ye-NFC yezinhlelo zokusebenza zekhakiti.
I-Field Communications Communications (I-NFC) - I-Technology
Ubuchwepheshe be-Communication Field Field buyathandeka ngempela.
I-NFC isebenza ngezindlela ezimbili.
- Isebenzayo - Imodi esebenzayo: Kule modeli, zombili amadivaysi akhiqiza amasimu abo e-RF. Lokhu kuzobe kwenzeka ukuthi amadivaysi amabili eselula asetshenziselwa ukushintshanisa idatha.
- Isebenzayo - Imodi Ye-Passive: Kule mode, enye yamadivayisi idala insimu ye-RF kanti enye idivayisi isebenzisa insimu ukuze ikwazi amandla futhi ixoxe. Idivayisi esebenzayo ivame ukuba "umfundi" futhi idivaysi ye-passive yiyona "tag".
Idivayisi esebenzayo noma umfundi ngokuvamile ukuvota kumadivayisi aseduze we-NFC. Idivaysi noma ithegi ehamba phambili iqala ukulalela uma ifika ngaphakathi kwamamitha ambalwa wedivayisi esebenzayo ye-NFC. Umfundi uzobe esexhumana nomaki ukuze anqume ukuthi yiziphi ubuchwepheshe bokubonisa ezingasetshenziswa. Njengamanje, kunezinhlobo ezintathu zobuchwepheshe bokubonisa:
- I-NFC-A, okuyi-RFID Uhlobo A
- I-NFC-B, okuyi-RFID Uhlobo B
- I-NFC-F, okuyi-FeliCA
Uma ithegi isabela lapho ubuchwepheshe bokubonisa kufanele busetshenziswe khona, umfundi uzosungula isixhumanisi sokuxhumana nayo yonke imingcele edingekayo. Amanye amathegi aphinde aqoshwe ngakho abafundi bangabuyekeza idatha. Cabanga ngekhadi lesikweletu elivunyelwe le-NFC. Ikhadi lesikweletu lingadlula idatha efana nenombolo yekhadi lesikweletu noma usuku lokuphela kwesikhathi.
Ifoni ehlomile ye-NFC ingenza ngendlela esebenzayo noma ehleliwe. Njengendlela yokukhokha ekusetshenzisweni okuthengisayo, i-NFC ifoni ehlonyelwe izokwenza ngendlela ye-passive ngemishini esiteshini sokuhlola esisebenza kwimodi esebenzayo. Kwesinye isicelo, i-NFC ifoni ehlomele ingase isetshenziswe ukuskena ithegi ephaketheni ukuze ithole idatha eningiliziwe mayelana nokuqukethwe.
Kulokhu, ifoni isebenza kwimodi esebenzayo.
Isihluthulelo esicacile sokwamukelwa kwetheknoloji ye-NFC yilapho kudalwa i-NFC ehlanganisiwe yokujikeleza noma i-chips. Isizathu sokuba i-NFC ibe ezindabeni zakamuva yile namba ekhulayo yabakhiqizi kuhlanganise nalezi zips kumadivayisi wabo weselula. Ekuphenduleni, imakethe kuyodingeka ukuthi ikhiqize izindleko eziphansi, amathegi e-NFC azimele asemakethe ukuze akhule. Omunye wabathuthukisi bezentengiselwano ezihamba phambili zale teknoloji i-Innovision Research & Technology evela e-UK, eyatholwa yi-Broadcom Corporation. Bheka ukukhululwa kwe-Broadcom kusisombululo se-NFC sokumaka.
Inxusa Yezokuxhumana (NFC) - Ukuphepha
Isidingo esiyisisekelo sokuphepha kungenxa yokuthi amadivaysi amabili kufanele abe ngaphakathi kusondelene kakhulu nomsebenzi. Idatha phakathi kwamadivayisi amabili e-NFC axhumanisa ingafakwa ngekhodi ngokusebenzisa ama-AES. Ukubethela akudingeki yizinga elijwayelekile, kodwa ngokuqinisekile kuyoba umkhuba omuhle kakhulu. Ukungabikho kokubethela kwakungenhloso ukuze kuqinisekiswe ukuthi ubuchwepheshe buhambisana nokuqaliswa kokuqala kwe- RFID .
Ukudliwa yizinto zokukhathazeka ngokuphathelene nokuphepha. Ngokweqile, idivaysi yesithathu ingangena esithombeni bese iba idatha. Yingakho ukubethela kungadingeka ezintweni ezifana nokuthengiswa kwekhadi lesikweletu.
Uma kwenzeka ukuthi idivayisi ye-NFC ekulungele ukwebiwe, kunengozi ukuthi ikhadi lesikweletu, isibonelo, lingasetshenziswa ukuthenga. Isimo sedivayisi eselula esele se-NFC eyebiwe singavinjelwa ngokusebenzisa iphasikhodi noma iphasiwedi ukuqedela ukuxhumana.
Abacwaningi babheka izindlela zokubhekana nokuvikeleka kwamakhadi esikweletu kanye namanye amadivaysi angenawo. Uma kuziwa ekuxhumaneni okuphephile phakathi kwamadivayisi amabili anikwe amandla we-NFC, ukubethela kuyindlela engcono kakhulu yokuvikela ukusakaza kokuxhumana.
Isitatimende se-NFC Elevator
Ngakho-ke manje ukuthi wazi ngokwanele mayelana Nokuxhumana Kwenkambu Eseduzane ukugibela i-elevator ne-CEO yakho bese uyichazela yona, lapha siya khona.
CEO:
Sawubona uJimmy. Bengifunda mayelana ne-NFC kwenye yezinguquko zamabhulogu wami wezintandokazi zendlovukazi eyintandokazi. Kwenzeka kanjani lokho, noma kunjalo "?
Umuntu we-IT:
Ukuxhumana Okuseduze Kwendawo kuyathandeka kakhulu futhi kuzoqhubeka nokuvuthwa. Uyazi ukuthi ama-chips afakwa kuwo wonke ama-iPhones amasha avumela i-NFC ukuthi isebenze futhi izoqhuba ukutholwa. Nakuba ubuchwepheshe buvame eJapane naseYurophu ngonyaka ka-2011, i-US yayiphuza ukuyamukela. Noma kunjalo, ubuchwepheshe buvumela ukuxhumana okulula phakathi kwamadivayisi amabili anikwe amandla we-NFC. Enye yamadivayisi ingase ibe yile divayisi efana nelebuli efakwe ubuchwepheshe be-NFC. I-iPhone yakho ingakwazi ukulanda idatha kusuka kwikhompyutha yakho, ukuthenga ukudla kwasemini, noma ngisho nokubuka ulwazi lomkhiqizo wethu ngokuyibeka eduze komthamo we-NFC ngomshini noma idivayisi. Cabanga ukuthi imikhiqizo yethu i-NFC imakiwe futhi amakhasimende ethu angasakaza i-iPhone yawo eduze komaki we-NFC futhi athole ulwazi lomkhiqizo noma asebenze. UCABANGANI? Ingabe kufanele senze ubufakazi bokucabanga?
