Yintoni umntu omele u-IT adinga ukwazi malunga noNxibelelwano lweeNdawo ezisondeleyo
UNxibelelwano lweeNdawo ezisondeleyo (NFC) iteknoloji ye-wireless ye-electromagnetic eyenzelwe ukunxibelelana phakathi kwezixhobo zombini. UNxibelelwano lweeNdawo ezisondeleyo okanye i-NFC yenzelwe ukunxibelelana phakathi kweendlela ezikude kakhulu. I-NFC yayiseendaba kwi-2014 ngenxa yeendlebe zokuthi i-Apple iya kubandakanya iteknoloji ekukhululeni okulandelayo kwe-iPhone. I-Google ibandakanya iteknoloji kwi- Android kunye ne-Samsung sele ifakwe kwezinye iifowuni zabo.
Cinga ukuba i-CEO evela kwinkampani yakho iyanqabela kwi-elevator njengoko ifuna ukuvala. Uthi, "Sawubona uJimmy, ndafunda nge-NFC kwenye yeeblogi zamathambo ezithandayo zendlovukazi yam intandokazi. Izinto zokuqala kuqala. Sungcangcazela. Ekubeni ungumfundi oqhelekileyo kweli candelo, ulungiselele "isitatimende se-elevator" malunga neNxibelelwano yeeNdawo eziPhezulu. Isitatimende se-elevator okanye iziphumo zentetho ye-elevator ukusuka kwimeko xa unemizuzu embalwa ukuchaza okanye ukubeka into kwisigqeba. Ingcamango kukuba isitatimende se-elevator sisetyenziswe. Ixesha elibalulekileyo kuba unalo ubude bendlela yokukhwela ukukhupha konke. Masifumane isitatimende sakho sokuphakamisa silungele ukuNxibelelana kweNgcaciso yoMmandla okanye iNFC.
UkuNxibelelana kweeNdawo ezisondeleyo (NFC) - I-Primer
UluNxibelelwano lweeNdawo ezisondeleyo (NFC) iteknoloji engabandakanyeki esebenza kwimiba engama-4 centimeters. Cinga ngokusindisa i-iPhone yakho kufuphi nomfundi wekhadi lokuthenga ngetyala kwi-counter of Chipotle.
I-NFC isekelwe kumgangatho wokunxibelelana ocacisa indlela ezimbini izixhobo ezisungula intsapho kwintanethi yontanga ukuze utshintshe idatha. I-NFC isebenzisa imithombo yomsakazo ye-electromagnetic ukuthetha. Oku kuhambelani neBluetooth okanye i- Wi-Fi esebenzisa ukuthunyelwa kwerediyo. Nangona kunjalo, i-NFC iyahambelana nezobuchwepheshe.
Kukhuselekile ngokwemvelo njengoko umda wemimandla usondele kakhulu. Yilungele ukukhupha i-CEO yakho ngedatha ethile:
- I-UFC isebenza kwi-13.56 MHz kwaye inemodi yokufunda nokubhala ngo-2013.
- UFC idluliselwa kwisilinganiso ukuya kwi-424 Kbits / yesibini.
- I-UFC isebenzisa imilinganiselo evela kwi-ISO, i-ECMA, ne-ETSI.
UkuNxibelelana kweeNdawo ezisondeleyo (NFC) - Imbali
I-Sony kunye ne-Phillips zikhokela abantu abanokuqala be-NFC namhlanje, kodwa imvelaphi yezinga elingenazintambo libuyela emuva ngasekupheleni kuka-2003, xa ivunyiwe njenge-ISO / IEC. Ngo-2004, i-Nokia, i-Sony kunye ne-Phillips yakha iForam ye-NFC, enamalungu angaphezu kwama-200 kuquka nabakhiqizi, abaphuhlisi, namaziko eenkonzo zezemali namhlanje.
Ngo-2006, iNkundla ye-NFC yabonisa iteknoloji kwaye yakha imephu yayo yokuqala. Izilingo ezininzi zeteknoloji zenzeke ngo-2007 no-2008, kodwa ayizange ichithe ngenxa yokungabikho kwenkxaso yabathwali kunye neebhanki. I-NFC ilungele ukukhutshwa, njengoko abenzi bezilwanyana eziphambili baquka iteknoloji kwimveliso yabo. Ukususela ngo-2011, i-NFC iteknoloji yayivame kakhulu e-Asia, eJapan naseYurophu. Nangona kunjalo i-US iqalisa ukubamba.
UkuNxibelelana kweeNdawo ezisondeleyo (NFC) - Izicelo
Izicelo ze-NFC zibonakaliswa. Nazi izimbalwa ezimbalwa:
- Iifowuni ezimbini ze-NFC zinokutshintshisiswa kwedatha ngokuzibetha okanye ukuzisondeza kunye.
- Isixhobo sekhamera se-NFC singadlulisela iifoto kwi-NFC ikhompyutha eneekhompyutheni okanye i-HDTV.
- I-NFC eneekhompyuter ikhompyutha ingadlulisela idatha kwisixhobo eselula.
- Ukusetyenziswa kwefowuni yeselula ye-NFC ukujonga kwaye uhlawule kwiirejista yemali-i-wallet eyiyo.
- Ukusetyenziswa kwezixhobo zeselula ze-NFC ukuthenga ukuthengiswa koomatshini.
- Ifowuni yeselula ye-NFC inokuhlawula imitha yokupaka.
- Ifowuni yeselula ye-NFC inokufikelela kwimali evela kwi-ATM.
- Ukusetyenziswa kwefowuni yeselula ye-NFC yee-ticketing applications.
UkuNxibelelana kweeNdawo ezisondeleyo (NFC) - IThekhnoloji
Itheknoloji yoNxibelelwano oluSondelene noNxibelelwano oluSondezayo inomdla kakhulu
I-NFC isebenza ngeendlela ezimbini.
- I-Active - Imoya esebenzayo: Kule ndlela, zombini iifowuni zenza iiRF zazo. Oku kuya kuba imeko yokuba izixhobo ezimbini ezisetyenziselwa ukutshintshisisa idatha.
- I-Active - I-Passive Mode: Kule ndlela, enye yeefowuni ivelisa insimu ye-RF kwaye enye ifowuni isebenzisa insima ukuba ikwazi amandla kunye nokuthetha. Isixhobo esisebenzayo sisoloko sifana "umfundi" kwaye isixhobo esicwangcisiweyo si "tag".
Ifowuni esebenzayo okanye umfundi ngokubanzi ukupota kwiiNFC ezikufutshane. Isixhobo esicatshulwayo okanye itekisi iqalisa ukuphulaphula xa kufike kwiiyunithi ezimbalwa zecandelo elisebenzayo le-NFC. Umfundi uya kuthi ke athethe itekisi ukwenzela ukuba abone ukuba yiyiphi i-teknoloji yokubonisa engasetyenziswa. Okwangoku, kukho ubuchwepheshe abathathu bokubonisa:
- I-NFC-A, eyi-RFID Uhlobo A
- I-NFC-B, eyi-RFID Uhlobo B
- I-NFC-F, eyiFeliCA
Xa ithe ithempendulo isabela apho iteknoloji yokutshintshwa kufuneka isetyenziswe, umfundi uya kuseka umnxibelelwano woqhagamshelwano nazo zonke iiparameter eziyimfuneko. Amanye amathegi aphinde ahlaziywe ukuze abafundi bakwazi ukuhlaziya idatha. Cinga ngekhadi lekhredithi enikwe amandla yeNFC. Ikhadi lesikweletu lingadlulela kwidatha efana nenombolo yekhadi lesikweletu okanye umhla wokuphelelwa yisikhathi.
I-NFC ifowuni exhotywe inokusebenza ngendlela ekhutheleyo okanye ehambelanayo. Njengendlela yokuhlawula kwisicelo sokuthengisa, i-NFC ifakwe ifowuni ifake imodeli ye-passive kunye nezixhobo kwisitishi esibhekisele kwisimo esisebenzayo. Kwesinye isicelo, i-NFC ifowuni enefowuni ingasetyenziselwa ukuskena itekisi kwiphakheji ukufumana idatha echanekileyo malunga nokuqukethwe.
Kule meko, ifowuni isebenza kwimodi esebenzayo.
Isicaciso esicacileyo sokwamkelwa kwetheknoloji ye-NFC kukudalwa i-NFC isiphaluka ezidibeneyo okanye ii-chips. Isizathu sokuba i-NFC ibe kwiindaba eziza kutshanje yinyuka ekhulayo yabakhiqizi kuquka ezi ziphulo kwiisistim zabo eziphathekayo. Ekuphenduleni, imarike iya kufuneka ivelise iindleko eziphantsi, iiplani ezizimeleyo ze-NFC zithengisa iimarike. Omnye wabathuthukisi bezobugcisa bezobugcisa be-Innovision Research & Technology kusukela e-UK, eyafunyanwa yi-Broadcom Corporation. Jonga ukukhutshwa kwe-Broadcom kwikhompyutheni ye-tagging ye-NFC.
UkuNxibelelana kweeNdawo ezisondeleyo (NFC) - Ukhuseleko
Isidingo esisisiseko sokhuseleko kukuba kuba zixhobo zombini kufuneka zibe ngaphakathi kusondele kakhulu kumsebenzi. Idatha phakathi kwezixhobo zombini ze-NFC zokudibanisa zingabhalwa nge-AES imigangatho. Ukubhaliweyo akufunwa ngumgangatho, kodwa ngokuqinisekileyo kuya kuba yinto engcono kakhulu. Ukungaphumeleli kwe-encryption kwakungenjongo yokuqinisekisa ukuba iteknoloji iyahambelana nokuphunyezwa kwangaphambili kwe- RFID .
I-Eavesdropping yinto enokukhathazeka ngokuphathelele ukhuseleko. Ngokweqhinga, ifowuni yesithathu ingangena emfanekisweni ize ibambe idatha. Kungenxa yoko ukubethelwa kubakho kuyimfuneko kwizinto ezifana nokuthengiswa kwekhadi lesikweletu.
Xa kwenzeka ukuba i-NFC isilungele isitshixo esele sibiwe, kukho umngcipheko ukuba ikhadi lokuthenga ngetyala, umzekelo, lingasetyenziselwa ukuthenga. Isimo se-NFC esele esele sefowuni esilungile sinokuthintelwa kunye nokusetyenziswa kwekhowudi yephasiwedi okanye iphasiwedi ukugqiba unxibelelwano.
Abaphandi bajonga iindlela zokujongana nokhuseleko kumakhadi-mboleko nakwezinye izixhobo ezingabonakaliyo. Xa kuziwa ekunxibelelaneni olukhuselekileyo phakathi kwamadivayisi anikwe amandla e-NFC, ukubhalwa kwemfihlo kuyindlela efanelekileyo yokukhusela umyalezo wokunxibelelana.
I-NFC Elevator Statement
Ngoko ngoku ukuba uyazi ngokwaneleyo malunga noNxibelelwano lweeNdawo ezisondeleyo ukukhwela i-elevator kunye ne-CEO yakho kwaye uyichazele kuye, silapha.
CEO:
Hi Jimmy. Ndandifunda malunga neNFC kwenye yeeblogi zamathambo ezithandwayo zendlovu. Ngaloo msebenzi, kunjalo "?
Umntu we-IT:
UkuNxibelelana kweeNdawo kusondelelene kwaye kuya kuqhubeka kukhula. Uyazi ukuba ii-chips zifakiwe kuzo zonke ii-iPhones ezintsha ezenza i-NFC isebenze kwaye iya kuqhuba ukuthotyelwa. Ngoxa i-teknoloji ixhaphakile eJapan naseYurophu ngo-2011, i-US yayicotha ukuyifumana. Nangona kunjalo, iteknoloji ivumela uxhulumaniso olulula phakathi kweefowuni ezimbini ezincedisayo zeNFC. Esinye sezixhobo sinokuba isixhobo esingenanto njengaleyibhile efakwe kwi-NFC. I-iPhone yakho inokukwazi ukukhuphela idatha kwi-laptop yakho, ithenge isidlo sasemini, okanye ukhangele ulwazi lwentengo yethu ngokuyifaka kwi-tag ye-NFC ilungile okanye ifowuni. Cinga imveliso yethu yi-NFC ethengiwe kwaye abathengi bethu banokushukumisa i-iPhone yabo kufuphi ne-NFC tag kunye nokufumana ulwazi lomkhiqizo okanye lijongane. Ingaba ucinga ntoni? Ngaba kufuneka senze ubungqina bombono?
