I-NFC kwifowuni - yintoni na nendlela yokuyisebenzisa?

I-NFC kwifowuni iteknoloji yokunxibelelana ne-wireless ephezulu enefuthe elifutshane elikuvumela ukuba uthengise ngaphandle kolwazi phakathi kwezixhobo ezimbini. I-NFC isekelwe kwi-RFID, oku kubonwa kwe-frequency frequency, yindlela yokulungisa umbane.

Yintoni "i-NFC"?

I-NFC iteknoloji ngaphandle koqhagamshelwano, iyakwazi ukufunda nokuthumela ulwazi kwiidivaysi kwimizuzu emide kakhulu. Isicatshulwa sithetha "Ulwaphulo olusondeleyo lweFild". Isekelwe kumgaqo wokutshintshiselwa kwempawu zomsakazo ezifana neBlutuz, kodwa kukho umehluko omkhulu. I-Bluetooth idlulisa idatha kwiimitha ezide, amamitha angamakhulu amitha, kwaye i-NFC ayithathi ngaphezu kwama-10 cm. Le teknoloji yaphuhliswa njengesandiso samakhadi angabandakanyekanga, kodwa ngokukhawuleza yafumana udumo, kwaye abaphuhlisi bafumene ityenziswe kwezinye iifowuni.

Kukho iindlela ezintathu zokusebenzisa le teknoloji kwiselula:

Indlela yokufunda;
ukulinganisa, xa ifowuni isebenza, njengekhadi lokubhadela okanye idlula;
Imodi yeP2P, xa ulwazi lutshintshana phakathi kweefowuni.

I-chip igcinwe kwiselfowuni, kwaye isetyenziswe njengendlela yokuhlawula, kunokwenzeka ukubhuka amathikithi, ukuhlawula imoto yokupaka okanye ukuhamba ukuya kwi-metro, kwaye uqinisekise ukulawulwa kokungena. Ngombulelo kwinkqubo yezobugcisa ngaphandle kokuthintana, iCardCard PayPass kunye neVisa PayWave amakhadi anee-antenna ezidibeneyo ziye zavela, eziqwalasela indima ye-NFC, izicelo eziphuhlisiwe ze-Android-smartphones.

Yintoni i-NFC kwi-smartphone? Ngoqhagamshelwano olusondeleyo, iifowuni ezimbalwa zidibaniswe nokufakelwa kwefomtic field, xa i-antennas edibeneyo yokudibanisa ifake umfundisi. Ngaphantsi kwezenzo ze-NFC, iifom kwi-spectrum ye-13.56 Megahertz yabelwe, kwaye izinga lokudluliswa kolwazi likwazi ukufikelela kwiikhilobithi ezingama-400 ngesibini. Isixhobo sisebenza ngeendlela ezimbini:

Esebenzayo . Zombini zixhobo zibonelelwa ngombane wamandla kwaye zithumele ulwazi ngolunye uhlangothi.
I-Passive . Amandla endle enye yezixhobo asetyenziswa.

Ziziphi iifowuni ezinayo i-NFC?

I-NFC kwifowuni inikeza ithuba lokuhlawula ukuthenga ngokuchukumisa ifowuni kwisigxina, lo luhlobo lwekhadi lebhanki kwiseli. Kwiminyaka emithandathu edlulileyo, kwakukho izixhobo ezimbalwa ezisekela i-NFC, kodwa ngoku iziputi zixhotywe ngamacwecwe, amawashi kunye nezinye izixhobo. Ziziphi iifowuni ezi zixhobo:

Apple - yonke imizekelo ye-iPhones;
U-Sony-umyalelo we-Xperia S, L, Z;
Samsung Galaxy S;
HTC #
LG;
Motorola;
Nokia-Lumia.

Ndiyazi njani ukuba ifowuni ixhasa iNFC?

Indlela yokujonga i-NFC, ngaba ifowuni? Kukho iindlela ezininzi:

Susa ikhava yangemuva ye-smartphone kwaye uhlole ibhetri yebhethri, kufuneka ibhalwe ngokuthi "NFC".
Kwisetingi, funda ithebhu ye "Wireless Networks", nqakraza "Ngaphezu", ukuba iteknoloji iyatholakala, umgca uvela negama lobuchwepheshe.
Gcina isandla sakho phezu kwesikrini, vula ikhefu lezaziso, apho olu khetho luya kubhaliswa khona.

Ukuba akukho NFC, kufuneka ndiyenze ntoni?

I-NFC kwifowuni - zeziphi iimodyuli? Kukho iintlobo ezisisiseko:

makhadi;
izixhobo zangaphandle;
microcircuits;
Iimodyuli ze-NFC;
izitifiketi.

Imodyuli ye-NFC ingathengwa kunye neefowuni, kodwa zithengiswa kwaye zodwa. Izikhonkwane zifakwe kwi-hull, ziza ezimbini iintlobo:

Esebenzayo. Ukunikezela ngolwazi nge-Wi-Fi / i-Bluetooth yesiteshi, kodwa udle amandla amaninzi, ngoko kufuneka uhlaziye rhoqo.
I-Passive. Musa ukuthetha kunye nefowuni kwaye ungayibhali kwidivaysi ngokusebenzisa iziteshi zokunxibelelana zeselula.

Indlela yokufaka i-NFC-chip kwifowuni?

Ukuba akuyiyo ekuqaleni kwisixhobo, imodyuli ye-NFC yefowuni inokuthengwa kwaye ifakwe. Kukho iindlela ezimbini ongakhetha kuzo:

I-NFC-simka, ngoku bathengiswa ngabasebenzisi abaninzi beefowuni.
I-antenna yeNFC. Ukuba akukho ndawo esondeleyo, le ndlela yindlela ephuma phambili. Kwiironons zokunxibelelana, ezi zixhobo zikhoyo, zihlanganiswe kwikhadi le-sim, phantsi kwekhava yefowuni. Kodwa kukho enye engezantsi: ukuba isicatshulwa sangasemva asisuswanga okanye umgodi wekhadi lek sim, ungenako ukufaka i-antenna

Unokukwenza njani i-NFC?

Isixhobo kunye ne-NFC asiyiyo kuphela isikhwama sekhredithi, ukuhamba kunye ne-Isaphulelo, iimpawu ezizodwa zikunceda ukufunda idatha malunga nempahla kwiivenkile, malunga nantoni na kwiimyuziyam kunye neembali. Uguquka njani?

Kwisetingi, khetha "amanethiwekhi angenazintambo", ngoko - "Ngaphezu".
Ubhaliso oluyimfuneko luya kubonakala, phawula "Qalisa".

Ukuba i-smartphone yakho inesixhobo se-NFC, kufuneka usebenze kwi-Android Beam:

Kwizicwangciso, nqakraza ithebhu ephezulu.

Cofa kwi-NFC-switch, umsebenzi we-android usebenza ngokuzenzekelayo. Ukuba oku kungenzeki, kufuneka ucofe kwi "Android Beam" ithebhu kwaye ukhethe "vumela".

Ukunxibelelana nakanjani, kufuneka uqiniseke ukuba zombini iifowuni zixhasa i-NFC ne-Android Beam, kufuneka ubenze kuqala. Iskimu sezenzo solu hlobo:
Khetha ifayile ukuthumela.
Cinezela iifowuni zangemva zeefowuni kunye.
Gcina ifowuni de i-beep eqinisekisa ukuba utshintsho luphelile.

Kungakhathaliseki uhlobo lwefayili, iteknoloji ye-NFC ithatha i-algorithm yolwazi olulandelayo:

Gcina ifowuni kuphela icala eliphambeneyo komnye nomnye.
Lindela ade bafumane.
Qinisekisa isicelo sokudlulisa.
Lindela umyalezo wokugqitywa kwenkqubo.

Iimpawu zeNFC

Umsebenzi we-NFC kwigajethi ikunika uncedo olukhulu:

Ukuthinta ifoni - kunye nedatha edluliselweyo;
uluhlu olubanzi lwezicelo;
iteknoloji ihlangabezana nemigangatho yecandelo
Ukusebenza kwe-transmitter ephantsi kunye nebala lokungcebeleka liqinisekisa ukutshintshwa okukhuselekileyo.

I-NFC kwifowuni okanye nakwezinye izixhobo - into efanelekileyo kakhulu ofuna ukuyifumana isicelo esifanelekileyo sale divayisi?

Izixhobo zeBluetooth nazo zixhasa i-NFC, umzekelo omnye ngumhlathi weNokia Play 360.
Ukuze wenze i-wallet ephathekayo yeselula, kufuneka ufake kunye nokuqwalasela isicelo se-Google Wallet.
I-tags ze-NFC zivumelekile ukuba zisetyenziswe kwinkqubo ngezicelo, ziyakwazi ukuvula umqhubi wendlela, idlulise iselula kwimodi yokuthula kwaye ize ifake iwashi ye-alamu.
Ngokusebenzisa i-NFC, kulula ukuthumela intlawulo kumhlobo, yenza ukuba ngumhlobo, kwaye kunye ngokuhlanganyela uthathe inxaxheba kumdlalo kubasebenzisi abaninzi.
