I-teknoloji ye-NFC ingenza olunye usuku lube ngumgangatho wokuthenga izinto kwiivenkile usebenzisa amadivayisi eselula. Ingasetyenziselwa ukwabelana ngeentlobo ezithile zeenkcukacha zedijithali ngala macebo malunga nenjongo yolwazi okanye yentlalo.
Uninzi lweefowuni luncedisa i-NFC kuquka i-Apple iPhone (ngokuqala nge-iPhone 6) ne-Android. Bona iifowuni ze-NFC: Uluhlu oluchanekileyo lokuphulwa kwamanqaku athile. Le nkxaso ingafumaneka nakwezinye iipilisi kunye neengubo zokugqoka (kuquka i-Apple Watch). Iinkqubo ezibandakanya i- Apple Pay , i- Google Wallet kunye ne- PayPal inkxaso yindlela eqhelekileyo yokusetyenziswa kwentlawulo yeeteknoloji.
I-NFC ivela kwiqela elibizwa ngokuba yiForam ye-NFC ephuhlise imilinganiselo ebalulekileyo yale teknoloji phakathi no-2000. Iforam ye-NFC iyaqhubeka nokuqhubela phambili uphuhliso lwetheknoloji kunye nokuthotyelwa kwamashishini (kubandakanywa nenkqubo yokuqinisekisa isistim yezixhobo).
Indlela iNFC isebenza ngayo
I-NFC ifom yeTeknoloji yeRadio Frequency Identification (RFID) esekelwe kwi-ISO / IEC 14443 kunye ne-18000-3. Esikhundleni sokusebenzisa i- Wi-Fi okanye i- Bluetooth , i-NFC isebenzisa le miqathango yokunxibelelana engenazintambo. Eyakhelwe indawo yokuhlala ephantsi kakhulu (ixabiso elingaphansi kweBluetooth), i-NFC isebenza kwibanga le-frequency (13,56 MHz ) kwaye lixhasa kuphela uxhaphalo lwe-networkwidth oluphantsi (ngaphantsi kwe-0.5 Mbps ). Ezi zibonakaliso zeziganeko zikhokelela ekufikeleleni komzimba we-NFC ngokukhawulelana nje ngamasentimitha ambalwa (ngokobuchwepheshe, ngaphakathi kweesentimitha ezine).
Amadivaysi axhasayo i-NFC aqulethe iqhosha lokunxibelelana elifakwe kwi-radio transmitter. Ukusungula uxhumano lwe-NFC kufuna ukuzisa ifowuni ukuba ibe kufuphi kufuphi nenye inkontileka ene-NFC. Kuyinto eqhelekileyo ukuchukumisa ngokomzimba okanye ukudibanisa ezimbini izixhobo zeNFC kunye ukuqinisekisa ukuxhamla. Ukuqinisekiswa kwenethiwekhi kunye nokusetyenzwa kokuxhunywa kwenzeka kwenzeka ngokuzenzekelayo.
Ukusebenza ngeTesha zeNFC
"Iifayile" kwi-NFC ziyi-chips ezincinci, ezifakwe ngaphakathi kwiimpawu okanye izinto ezingundoqo) eziqulethe ezinye iinkcukacha ze-NFC ezingayifunda. Ezi tags zisebenza njengamakhodi e- QR aqaliswe ngokutsha ngokuzenzekelayo (kunokuba afune ukuskena kwi-app).
Ukuqhathaniswa nokuthengiswa kwentlawulo ebandakanya uxhulumaniso lweendlela ezimbini phakathi kweefayile ze-NFC, ukusebenzisana neethegi ze-NFC kubandakanya kuphela indlela (ekuthiwa ngezinye izikhathi ngokuthi "ukufunda kuphela") ukudluliswa kwedatha. AmaTayiti azinayo iibhetri zawo kodwa kunoko isebenze ngokusekelwe kumandla avela kwisignali yomsakazo kwisixhobo sokuqalisa.
Ukufunda itekisi ye-NFC ibangela ukuba kukho nawaphi na amanyathelo athile kwisixhobo esifana ne:
- ukuguqula ivolumu yesandi, i-Bluetooth, kunye / okanye ukuxhumeka kwe-Wi-Fi kunye nokucima
- ngokuzenzekelayo uvula insiza kwaye uqalise umsebenzi (njengokudlala umculo okanye ukuqala i-timer)
- ukufunda idatha esuka kwithegi nokuyibonisa kwisixhobo (kwimephu, uluhlu loqhagamshelwano, okanye i-imeyile)
Iinkampani ezininzi kunye nezithengiso zithengisa i-NFC tags kumthengi. Iifayile zingalawulwa zingenanto okanye ngeenkcukacha zangaphambi kwekhowudi. Iinkampani ezinjengeGoToTags zokubonelela ngeekhompyutheni zeekhompyutheni eziyimfuneko zokubhala ezi tag.
NFC Security
Ukunika idivaysi kunye ne-NFC engabonakaliyo inxibelelwano engenazintlu ngokwemvelo iphakamisa ezinye iinkxalabo zokhuseleko, ngakumbi xa zisetyenziselwa ukuthengiswa kwemali. Ukufikelela kwefutshane kwee-NFC isisinceda kunciphisa ingozi ekhuselekileyo, kodwa ukuhlaselwa okubi kunokwenzeka ngokunyanzelisa i-radio idibanisa ifowuni idibanisa (okanye ukuba idivayisi ngokwayo). Xa kuthelekiswa nokunciphisa ukukhuselwa kwamakhadi esikwereti esikhatywayo e-US kwiminyaka yamuva, iteknoloji ye-NFC ingaba yindlela efanelekileyo.
Ukunciphisa idatha kwiimpawu ze-NFC zangasese kungakhokelela kwimicimbi enzulu. Iifayile ezisetyenzisiweyo kumakhadi okuchonga umntu okanye iipassports, umzekelo, zinokuguqulwa ukuba zikhohlise ulwazi malunga nomntu ngenjongo yobuqhetseba.
