Ib qho kev qhia luv luv ntawm kev siv thev naus laus zis uas tsis yog siv rau kev them nyiaj tsis sib cuag nkaus xwb.

NFC yog dab tsi

NFC sawv cev rau Kev Sib Txuas Lus Zej Zog lossis lus "ze kev sib txuas lus". Cov cuab yeej siv no yog siv los hloov cov ntaub ntawv ntawm cov khoom siv ntawm qhov deb txog li 10 cm. Kev sib txuas lus yog tswj los ntawm kev sib nqus induction.

NFC tuaj yeem ua haujlwm hauv hom nquag thiab tsis ua haujlwm. Rau thawj, nws yog ib qho tsim nyog uas ob lub cuab yeej muaj lawv tus kheej lub zog, thiab rau qhov thib ob, ib qho txaus. Nyob rau hauv rooj plaub tom kawg, ib qho ntawm cov khoom siv tau txais nws lub zog ua haujlwm los ntawm electromagnetic teb ntawm lwm tus.

NFC nti nws tus kheej muaj qhov loj me me, uas tso cai rau nws los nruab rau hauv smartphones, hais lus, ntsiav tshuaj thiab lwm yam khoom siv txawb.

Dab tsi NFC tuaj yeem siv rau

Kev sib txuas lus nrog lwm yam khoom siv

Piv rau Bluetooth thev naus laus zis, NFC muaj kev sib txuas ceev nrawm ntawm cov khoom siv. Nyob rau tib lub sijhawm, qhov ceev ntawm cov ntaub ntawv hloov mus rau nws tus kheej hauv hom kev sib txuas lus nquag yog qhov tsawg. Tias yog vim li cas, hauv smartphones, NFC feem ntau tsuas yog siv los hloov kev sib cuag, txuas, sau ntawv, nrog rau kev tswj hwm ntawm daim ntawv qhia.

Thaum hloov cov ntaub ntawv loj, thev naus laus zis tsuas yog siv los txuas cov khoom siv, thiab cov ntsiab lus raug xa los ntawm Bluetooth lossis Wi-Fi. Qhov no txawm siv rau kev hloov cov yeeb yaj duab yooj yim lossis cov ntaub ntawv los ntawm "Xa" muaj nuj nqi.

Koj tuaj yeem paub qhov tseeb qhov chaw ntawm lub kav hlau txais xov nti hauv cov lus qhia rau lub cuab yeej. Txawm li cas los xij, feem ntau, lawv raug coj tawm mus rau tom qab ntawm rooj plaub. Yog li ntawd, cov xov tooj smartphones thaum txuas ntawm NFC yuav tsum ntsoos tawm tsam ib leeg nrog lawv lub nraub qaum.

Scanning thiab programming cim

Passive kev sib txuas lus hom tuaj yeem siv los nyeem cov ntaub ntawv los ntawm programmable NFC chips lossis hu ua cim npe. Lawv tsis muaj lawv tus kheej lub zog, thiab kev ua kom muaj zog tshwm sim los ntawm electromagnetic teb ntawm tus nyeem ntawv ntaus ntawv.

Lub hom phiaj tseem ceeb ntawm cov cim npe yog kom tau txais cov ntaub ntawv ntxiv txog ib yam khoom lossis ib qho kev tshwm sim. Hauv qee cov khw muag khoom, NFC cov cim twb tau hloov pauv barcodes. Los ntawm leaning tiv thaiv lub xov tooj smartphone, tus neeg yuav khoom tuaj yeem tau txais cov ncauj lus kom ntxaws txog cov khoom muaj pes tsawg leeg, txee lub neej thiab kev cia khoom.

Tsis tas li ntawd, cov cim npe yog siv los ua kom muaj ntau yam kev ua ntawm lub xov tooj smartphone - tig rau daim ntawv thov, hloov lub suab profile, xa lus, thiab lwm yam. Piv txwv li, koj tuaj yeem tsim ib lub cim los pib lub navigator thiab txuas rau lub tsheb. Thaum koj tso koj lub smartphone rau nws, lub gadget yuav pib txiav.

Cov cim npe yog programmed los ntawm cov ntawv thov tshwj xeeb ntawm lub smartphone, xws li NFC Cov Cuab Yeej.

Emulation cards

NFC gadgets tuaj yeem siv los ua raws li daim npav ntse siv raws li daim ntawv hla tebchaws, qhov tseem ceeb, lossis daim npav mus ncig. Txawm li cas los xij, nrog kev tuaj txog hauv tebchaws Russia ntawm cov nyiaj them poob haujlwm hauv Android Them, Apple Them thiab Samsung Them, lub hom phiaj tseem ceeb ntawm NFC nti hauv lub xov tooj smartphone yog emulation ntawm bank cards rau contactless them.

Txhawm rau them cov khoom siv NFC, koj tsuas yog yuav tsum nqa koj lub xov tooj smartphone mus rau lub davhlau ya nyob twg ntawm lub tshev tawm. Qhov tseem ceeb yog ua ntej txuas koj daim npav hauv txhab nyiaj mus rau qhov kev them nyiaj muaj rau koj lub smartphone.

Android Them muaj qhov kev pab cuam loj tshaj plaws los ntawm cov khoom siv, txij li, tsis zoo li cov kev pabcuam zoo sib xws los ntawm Apple thiab Samsung, nws tsis yog tsim rau cov khoom siv ntawm ib lub chaw tsim khoom. Txawm li cas los xij, ib qho ntawm cov kev them nyiaj no tuaj yeem siv yam tsis muaj kev ntshai thiab pheej hmoo.

Tsis muaj leej twg ntawm lub sijhawm them nyiaj xa daim npav rau lub davhlau ya nyob twg nws tus kheej. Hloov chaw, lub npe hu ua token yog siv - tus cim digital encrypted uas tau tsim tawm thaum daim npav qhib. Nws yog nws leej twg yuav tau nyeem raws li qhov tseem ceeb.

NFC ruaj ntseg npaum li cas

Cov cuab yeej siv nrog NFC tuaj yeem tau txais thiab xa cov ntaub ntawv ib txhij, uas tso cai rau lawv txhawm rau txheeb xyuas qhov tsis sib xws yog tias lub teeb liab tau txais tsis phim qhov kis tau tus mob.

Qhov kev pheej hmoo ntawm kev cuam tshuam ntawm koj cov ntaub ntawv yog qhov tsawg heev, tshwj xeeb tshaj yog muab cov cuab yeej siv tsawg kawg nkaus. Tib Bluetooth kev khiav hauj lwm nyob rau hauv kaum ntawm meters yog ntau yooj yim rau sab nraud cuam tshuam.

Qhov no kuj tseem siv tau rau cov ntsiab lus them nyiaj: lub token tsim rau kev them nyiaj tsis sib cuag yuav tsis tso cai rau cov neeg nkag mus nkag rau koj daim npav. Thiab qhov tseeb ntawm kev cuam tshuam tus cim encrypted zoo li tsis muaj tseeb.

Tsis tas li ntawd, kev them nyiaj tsis tiv tauj yuav tsum tau lees paub los ntawm tus ntiv tes, lo lus zais, lossis lub ntsej muag scan. Yog tsis muaj tag nrho cov no, kev yuav khoom tsis tuaj yeem ua. Qhov no txhais tau hais tias txawm tias lub xov tooj smartphone raug nyiag lawm, tsis muaj leej twg yuav siv tau los ua cov cuab yeej them nyiaj.

Cov smartphones twg txhawb NFC

Ib zaug xwb kim flagships muaj kev txhawb nqa rau cov thev naus laus zis no, tab sis tam sim no koj tuaj yeem yuav lub smartphone nrog NFC rau tsawg dua 10,000 rubles. Txawm li cas los xij, qhov no siv rau cov khoom siv Android. Ntawm cov nqi pheej yig tshaj yog Nokia 3, Samsung Galaxy J5, Motorola Moto G5s.

Hauv Apple ecosystem, lub xov tooj pheej yig tshaj plaws uas txhawb nqa Apple Pay yog iPhone SE, uas niaj hnub no raug nqi qis dua 20,000 rubles. Txhua tus qauv kim dua, pib nrog iPhone 6, kuj muaj NFC nti.

Yog tias koj tsis paub yog tias koj lub xov tooj Android muaj NFC, koj tuaj yeem tshawb xyuas nws los ntawm kev tshawb nrhiav los ntawm cov chaw. Feem ntau, cov yam ntxwv ntsig txog thev naus laus zis muaj nyob rau hauv Cov Kev Sib Txuas lossis Cov ntu Wireless. Tsis tas li ntawd, lub NFC icon yuav tsum muaj nyob rau hauv cov npe ntawm cov cim tso tawm sai hauv cov ntaub thaiv sab saum toj.
