Peb txhua tus tau siv rau qhov zoo li no hauv lub xov tooj smartphone li NFC. Thiab txhua yam zoo li pom tseeb nrog qhov no.
Ntau tus neeg tsis yuav smartphones yam tsis muaj NFC, xav tias nws tsuas yog kev yuav khoom xwb. Tab sis muaj ntau cov lus nug.
Tab sis koj puas paub dab tsi ntxiv qhov tshuab no tuaj yeem ua tau? Yuav ua li cas yog tias koj lub smartphone tsis muaj NFC? Yuav siv cov nti hauv iPhone li cas tsis yog rau Apple Pay? Vim li cas ho tsis ua haujlwm, tshwj xeeb nrog World cards?
Koj tseem tuaj yeem them cov khoom siv los ntawm nws ...
Hnub no peb yuav qhia koj seb nws ua haujlwm li cas thiab saib tag nrho cov ntsiab lus. Thiab qhov tseem ceeb tshaj plaws, vim li cas nws thiaj li yog qhov tsis txaus ntseeg tshaj plaws hauv koj lub smartphone!
NFC ua haujlwm li cas?
Tej zaum koj yuav paub tias NFC sawv cev rau Zej Zog Kev Sib Txuas Lus lossis hauv Lavxias - kev sib txuas lus luv luv.
Tab sis qhov no tsis yog cov ntaub ntawv zoo tib yam kis tau tus mob hauv xov tooj cua yoj. Tsis zoo li Wi-Fi thiab Bluetooth, NFC yog qhov ntse dua. Nws yog tsim los ntawm electromagnetic induction. Qhov no yog ib qho zoo heev los ntawm lub tsev kawm ntawv cov ntaub ntawv, cia kuv nco koj.
Lub tswv yim yog tias koj coj ib tus neeg xyuas pib uas tsis muaj hluav taws xob. Thiab koj tso tus neeg xyuas pib thib ob ntawm nws, uas muaj hluav taws xob. Thiab twv dab tsi? Hauv thawj tus neeg xyuas pib, qhov twg tsis muaj hluav taws xob, tam sim no pib ntws!
Txias, yog?
Thaum peb xub kawm txog nws, peb xav tias nws ua tsis tau! Tiag tiag? Koj tsav tsheb! Wb mus ua si Counter Strike, cov tub.
Zoo, thaum koj nqa koj lub xov tooj mus rau qee qhov NFC lossis tsis muaj lub zog, qhov me me hluav taws xob hluav taws xob ntawm lub xov tooj smartphone yog txaus rau cov hluav taws xob ntws mus rau hauv cov cim npe thiab cov microcircuits hauv nws ua haujlwm.
Oh yog. Txhua daim ntawv muaj ib daim ntawv me me. Piv txwv li, nyob rau hauv bank cards lub microchip sau txawm ib tug yooj yim version ntawm Java. Nws zoo li cas?
Tej zaum koj yuav tau hnov ββββcov ntawv luv RFID. Nws tau tsim 30 xyoo dhau los. Nws sawv cev rau Xov Tooj Cua Zaus ID. Thiab qhov tseeb nws tsuas yog tsim nyog rau kev txheeb xyuas. Ntau lub chaw ua haujlwm tseem muaj cov cim RFID.
Yog li NFC yog ib ceg siab heev ntawm RFID tus qauv thiab nyeem qee cov cim npe no. Tab sis qhov sib txawv tseem ceeb yog tias NFC tuaj yeem hloov cov ntaub ntawv, suav nrog cov encrypted.
NFC ua haujlwm ntawm qhov zaus ntawm 13,56 MHz, uas tso cai rau koj kom ua tiav qhov nrawm ntawm 106 txog 424 Kbps. Yog li cov ntaub ntawv mp3 yuav rub tawm hauv ob peb feeb, tab sis tsuas yog nyob deb li ntawm 10 cm.
Lub cev, NFC yog lub kauj me me. Piv txwv li, hauv Pixel 4 nws txuas nrog lub hau thiab zoo li qhov no.
Thiab yog li hauv Xiaomi Mi 10 Pro:
Thiab tam sim no nws yog lub sijhawm los tham txog dab tsi NFC tuaj yeem ua tau?
Kev ua haujlwm ntawm cov thev naus laus zis no thiab lwm yam, xws li RFID, tau piav qhia hauv tus qauv ISO 14443. Tseem muaj ntau yam khoom lumped ua ke: piv txwv li, Italian Mifare raws tu qauv thiab VME nyob rau hauv bank cards.
NFC yog hom USB hom-C ntawm lub ntiaj teb wireless, yog tias koj paub kuv txhais li cas.
Tab sis qhov tseem ceeb yog qhov no. NFC tuaj yeem ua haujlwm hauv peb hom:
- Active. Thaum ib lub cuab yeej nyeem lossis sau cov ntaub ntawv los ntawm lub cim lossis daim npav. Los ntawm txoj kev, yog, cov ntaub ntawv tuaj yeem sau rau NFC cim npe.
- Hloov ntawm cov cuab yeej sib koom ua ke. Qhov no yog thaum koj txuas wireless headphones rau koj lub smartphone lossis siv Android Beam - nco ntsoov qhov no. Nyob ntawd, kev sib txuas tau tshwm sim ntawm NFC, thiab cov ntaub ntawv hloov mus rau nws tus kheej tau tshwm sim ntawm Bluetooth.
- Passive Thaum peb lub cuab yeej ua piv txwv ua ib yam dab tsi passive: daim npav them nyiaj lossis daim npav mus ncig.
Vim li cas NFC yog tias muaj Bluetooth thiab Wi-Fi, vim lawv muaj ob qho tib si ceev thiab ntau yam.
NFC nyiaj tshwj xeeb yog raws li nram no:
- Kev sib txuas tam sim - ib feem kaum ntawm ib thib ob.
- Kev siv hluav taws xob tsawg - 15 mA. Bluetooth muaj txog li 40 mA.
- Cim npe tsis xav tau lawv tus kheej lub hwj chim.
- Thiab tsis yog li ntawd pom tseeb - ib qho luv luv, uas yog tsim nyog rau kev ruaj ntseg thiab kev them nyiaj.
Kuj tseem muaj Bluetooth Tsawg Zog, tab sis qhov ntawd yog ib zaj dab neeg sib txawv.
Rau dab tsi? Qhov no muab dab tsi rau peb?
Ntxiv rau cov xwm txheej uas twb muaj lawm: hla, them nyiaj thiab daim npav mus ncig, muaj cov ntawv thov uas tuaj yeem tso nyiaj rau daim npav Troika thiab lwm daim npav thauj.
Muaj ib daim ntawv thov - Bank card nyeem ntawv. Piv txwv li, nws tuaj yeem qhia qhov tseeb ntawm daim npav rho nyiaj. Kuv tsis paub tseeb tias qhov no yog kev coj ncaj ncees, tab sis daim ntawv thov nyob rau ntawm Play Market.
Los ntawm txoj kev, ntau tus neeg xav paub vim li cas Google thiab Apple Pay tsis ua haujlwm nrog Mir phaib? Nws tsis yog ib qho teeb meem ntawm technical nta. Qhov kev them nyiaj tsuas yog tsis pom zoo nrog cov kev pabcuam. Koj tuaj yeem them nyiaj los ntawm koj daim ntawv thov Android - Ntiaj Teb Them. Nws yog qhov tseeb tias nws yog buggy, tab sis nws tsis ua haujlwm nrog iPhone txhua!
Los ntawm txoj kev, lub neej hack. Yog tias koj lub Android tsis muaj NFC, tab sis koj xav them nyiaj tiag, koj yuav ua li cas? Koj tuaj yeem muab daim npav tso rau hauv qab lub hau. Tiv tauj peb. Muaj tseeb tiag, cov ntaub ntawv tuab yuav tsis kis tau txawm tias muaj cov nFC ua hauv - yog li kos.
Peb twb tau tham txog cov khoom siv, tab sis muaj qhov tseem ceeb thib ob - NFC cim npe. Lawv tuaj nyob rau hauv ob hom.
- Cov uas koj tuaj yeem sau cov ntaub ntawv. Lawv zoo li cov ntawv nplaum me me. Feem ntau lub cim xeeb muaj txog 700 bytes. Cov zoo sib xws tau tsim los ntawm Sony.

- Teem koj lub smartphone mus rau hauv kev pw tsaug zog hmo ntuj ntawm koj lub nightstand
- Koj tuaj yeem khaws qee cov ntaub ntawv rau hauv nws, piv txwv li tus password lossis BitCoin token. Tsuas yog zoo dua nyob rau hauv daim ntawv encrypted.
Daim ntawv no tuaj yeem nyeem los ntawm txhua lub xov tooj nrog NFC.
Yuav ua li cas yog tias koj tsis muaj NFC cim npe? Koj tuaj yeem xaj lawv, lawv raug nqi pennies.
Tab sis koj tuaj yeem nqa daim npav rho nyiaj tsis tu ncua lossis daim npav thauj, zoo li Troika. Cov no yog cov cim ntiag tug. Ib qho piv txwv yog koj daim npav rho nyiaj. Koj sau tsis tau dab tsi rau lawv.
Tab sis koj lub xov tooj smartphone tuaj yeem raug programmed ua txhua yam thaum zoo li no siv rau nws.
Yog tias koj muaj Android, koj tuaj yeem nruab daim ntawv thov piv txwv los yog . Hauv lawv koj tuaj yeem muab kwv yees li tib yam ua rau NFC cim npe. Tig Wi-Fi thiab hu rau / tawm, tso daim ntawv thov, tig rau hmo ntuj. Piv txwv li, koj tuaj yeem ua kom nws thiaj li thaum koj tso koj lub xov tooj rau ntawm daim npav Troika, koj li . kuv pom zoo!
Los ntawm txoj kev, qhov no yog dab tsi cov ntsiab lus ntawm Troika zoo li.
Koj tseem tuaj yeem nyeem ntawm hais txog ib tug txiv leej tub uas cog ib daim ntawv NFC ntawm nws txhais tes.
Dab tsi ntxiv tuaj yeem siv NFC rau?
Ib qho kev cog lus yog daim pib hluav taws xob. Mus rau xinesmas lossis concerts. Tam sim no lawv ua nws los ntawm QR code thiab nws tsis yog qhov txias, hauv kuv lub tswv yim. Txawm tias ntau lab tus Suav yuav tsis pom zoo nrog kuv.
Txog Apple
Yuav ua li cas yog tias koj muaj iPhone? Txhua tus xav tias NFC yog neeg xiam oob khab ntawm iPhone, tab sis qhov ntawd tsis muaj tseeb. Pib nrog iOS 11, uas yog, txij li xyoo 2017, Apple tau qhib kev nkag mus rau cov neeg tsim khoom. Thiab twb muaj ntau daim ntawv thov tib yam li hauv Android. Piv txwv li, NFC Cov Cuab Yeej.
Muaj tseeb, tseem muaj kev txwv: kev thauj mus los thiab daim npav hauv txhab nyiaj, piv txwv li, tsis tuaj yeem luam tawm. Peb xav tau cov cim tshwj xeeb, uas peb twb tau tham lawm.
Yuav ua li cas? iOS 13 qhia txog Commands feature (Siri). Thiab tam sim no nws tsuas yog nkag mus rau ib qho NFC cim npe. Yog li ntawm no koj tuaj yeem teeb tsa lub suab paj nruag siv Troika card. Los yog tig lub teeb ntse. Los yog ib pawg ntawm lwm yam. Cov pab pawg yog cov foob pob tiag tiag. Kuv tsis nkag siab tias vim li cas Android tsis muaj qhov no.
Kev them nqi
Yog tias los ntawm qhov no koj tau txiav txim siab tias koj paub txhua yam txog NFC thiab nkees ntawm cov ntawv thov tsis zoo no. Yog li ntawm no yog ib yam dab tsi tawg rau koj.
Muaj ib lub koom haum hu ua NFC Forum uas tau lees paub NFC. Feem ntau, txhua lub tshuab muaj lub koom haum zoo li no, thiab nws zoo yog tias tsuas muaj ib qho xwb.
Thiab tsuas yog lwm hnub lawv tso tawm lwm qhov hloov tshiab rau tus qauv. Thiab twv dab tsi? NFC tam sim no txhawb kev them nyiaj wireless. Yog, qhov tseeb, qhov no yog hom plaub ntawm kev ua haujlwm.
Koj nug dab tsi? Electromagnetic induction, nco ntsoov? Nrog nws pab.
Los ntawm txoj kev, Qi them nyiaj ua haujlwm raws nraim ntawm tib txoj cai. Tsuas muaj ib lub kauj loj dua.
Tab sis muaj ib qho teeb meem. NFC kauj yog me me, uas txhais tau hais tias lub zog them qis - tsuas yog 1 Watt.
Puas muaj peev xwm them lub smartphone ntawm qhov ceev no? Tsis txhob sim. Txawm li cas los xij, ib qho haujlwm rau qhov no tsis tau tsim.
Lub hom phiaj tseem ceeb yog qhov sib txawv - them lwm yam khoom siv nrog lub smartphone. Qhov no zoo li thim rov qab them nyiaj hauv Galaxy thiab lwm lub smartphones. Piv txwv li, koj tuaj yeem siv lub wireless headphones lawv tus kheej, thiab tsis yog los ntawm lawv. Qhov tseem ceeb, peb muaj lub wireless charger pheej yig heev uas muaj nyob rau hauv txhua lub xov tooj smartphone thiab tuaj yeem yooj yim tso rau hauv txhua lub cuab yeej ntse.
Los ntawm txoj kev, 1 Watt tsis yog tsawg dhau. Rau kev sib piv, txhua lub iPhones tshwj tsis yog 11 Pro siv lub charger 5-watt. Thiab lub zog ntawm kev them nyiaj rov qab wireless hauv cov flagships niaj hnub hloov pauv ntawm 5 lossis 7 W.
Tab sis muaj ib yam - qhov no feature yuav tsis ua hauj lwm rau cov qauv tam sim no. Smartphones nrog xws li ib tug feature yuav feem ntau yuav pib tshwm nyob rau hauv ib lub xyoo thiab ib nrab. Yog li khaws lub qhov muag tawm rau Samsung tshaj tawm qhov khoom no.
