Xov xwm

NFC yog luv-nqi wireless kev sib txuas lus thev naus laus zis.Cov thev naus laus zis no tau hloov zuj zus los ntawm kev txheeb xyuas lub xov tooj cua tsis sib cuag (RFID) thiab tau koom ua ke tsim los ntawm Philips Semiconductors (tam sim no NXP Semiconductors), Nokia thiab Sony, raws li RFID thiab kev sib txuas thev naus laus zis.

Ze ntawm Kev Sib Txuas Lus yog qhov luv luv, lub tshuab hluav taws xob ntau zaus uas ua haujlwm ntawm qhov deb ntawm 10 centimeters ntawm 13.56MHz.Kev sib kis ceev yog 106Kbit / sec, 212Kbit / sec lossis 424Kbit / sec.

NFC ua ke cov haujlwm ntawm tus nyeem ntawv tsis sib cuag, daim npav tsis sib cuag thiab cov phooj ywg-rau-tus phooj ywg ntawm ib lub nti, ua kom muaj kev txheeb xyuas thiab cov ntaub ntawv sib pauv nrog cov khoom siv sib xws hauv qhov luv luv.NFC muaj peb hom kev ua haujlwm: hom nquag, hom passive thiab hom bidirectional.
1. Active hom: Nyob rau hauv active hom, thaum txhua lub cuab yeej xav xa cov ntaub ntawv mus rau lwm lub cuab yeej, nws yuav tsum tsim nws tus kheej lub xov tooj cua zaus teb, thiab ob qho tib si pib ntaus ntawv thiab lub hom phiaj ntaus ntawv yuav tsum tsim lawv tus kheej lub xov tooj cua zaus teb rau kev sib txuas lus.Qhov no yog hom qauv ntawm kev sib txuas lus ntawm cov phooj ywg-rau-peer thiab tso cai rau kev sib txuas ceev heev.
2. Passive kev sib txuas lus hom: hom kev sib txuas lus passive tsuas yog qhov txawv ntawm hom nquag.Lub sijhawm no, NFC lub davhlau ya nyob twg yog simulated raws li daim npav, uas tsuas yog passively teb rau lub xov tooj cua zaus xa los ntawm lwm yam khoom siv thiab nyeem / sau cov ntaub ntawv.
3. Ob txoj kev: Hauv hom no, ob sab ntawm NFC lub davhlau ya nyob twg nquag xa tawm lub xov tooj cua zaus los tsim kev sib txuas lus taw tes-rau-taw tes.Sib npaug rau ob qho khoom siv NFC hauv hom nquag.

NFC, raws li qhov nrov nyob ze ntawm kev sib txuas lus thev naus laus zis hauv xyoo tas los no, tau siv dav.NFC daim ntawv thov tuaj yeem muab faib ua peb hom hauv qab no

1. Kev them nyiaj
NFC kev them nyiaj daim ntawv thov feem ntau yog hais txog daim ntawv thov ntawm lub xov tooj ntawm tes nrog NFC muaj nuj nqi los simulate bank card, daim npav thiab lwm yam.Daim ntawv thov kev them nyiaj NFC tuaj yeem muab faib ua ob ntu: daim ntawv thov qhib lub voj thiab daim ntawv thov kaw.Daim ntawv thov ntawm NFC virtualized rau hauv daim npav rho nyiaj yog hu ua daim ntawv thov qhib.Qhov zoo tshaj plaws, lub xov tooj ntawm tes nrog NFC muaj nuj nqi thiab ntxiv ib daim npav nyiaj hauv tuam txhab analog tuaj yeem siv los ua daim npav rho nyiaj los so lub xov tooj ntawm tes ntawm POS tshuab hauv khw muag khoom thiab khw muag khoom.Txawm li cas los xij, vim qhov muaj koob meej ntawm Alipay thiab WeChat hauv Suav teb, qhov feem pua ​​​​ntawm NFC hauv cov ntawv thov kev them nyiaj hauv tsev yog me me, thiab nws muaj kev sib txuas ntau dua thiab suav nrog Alipay thiab WeChat Them raws li kev pab Alipay thiab WeChat Them rau kev lees paub tus kheej. .

Daim ntawv thov ntawm NFC simulating ib daim npav yog hu ua daim ntawv thov kaw.Tam sim no, kev txhim kho ntawm NFC kaw-voj daim ntawv thov hauv Suav teb tsis yog qhov zoo tagnrho.Txawm hais tias kev thauj mus los rau pej xeem hauv qee lub nroog tau qhib NFC kev ua haujlwm ntawm cov xov tooj ntawm tes, nws tsis tau nrov.Txawm hais tias qee lub tuam txhab xov tooj ntawm tes tau sim NFC daim npav npav ua haujlwm ntawm cov xov tooj ntawm tes hauv qee lub nroog, lawv feem ntau yuav tsum tau qhib cov nqi pabcuam.Txawm li cas los xij, nws ntseeg tau tias nrog kev nrov ntawm NFC cov xov tooj ntawm tes thiab kev ua tiav tas li ntawm NFC thev naus laus zis, ib daim npav yuav maj mam txhawb nqa daim ntawv thov ntawm NFC xov tooj ntawm tes, thiab daim ntawv thov kaw yuav muaj lub neej yav tom ntej.

2. Daim ntawv thov kev ruaj ntseg
Daim ntawv thov ntawm NFC kev ruaj ntseg yog tsuas yog los virtualize lub xov tooj ntawm tes mus rau hauv cov ntawv tswj kev nkag, daim pib hluav taws xob, thiab lwm yam. NFC virtual access control card yog sau cov ntaub ntawv tswj kev nkag mus rau hauv NFC ntawm lub xov tooj ntawm tes, kom nkag mus rau kev tswj hwm kev ua haujlwm. tuaj yeem pom tau los ntawm kev siv lub xov tooj ntawm tes nrog NFC muaj nuj nqi thaiv yam tsis siv daim npav ntse.Daim ntawv thov ntawm NFC daim pib hluav taws xob hluav taws xob yog tias tom qab tus neeg siv yuav daim pib, daim pib xa cov ntaub ntawv daim pib mus rau lub xov tooj ntawm tes.Lub xov tooj ntawm tes nrog NFC muaj nuj nqi tuaj yeem virtualize cov ntaub ntawv daim pib mus rau hauv daim pib hluav taws xob, thiab lub xov tooj ntawm tes tuaj yeem rub ncaj qha ntawm daim pib kos.Daim ntawv thov NFC hauv kev ruaj ntseg yog qhov tseem ceeb ntawm NFC daim ntawv thov yav tom ntej, thiab qhov kev cia siab yog dav heev.Daim ntawv thov ntawm NFC hauv daim teb no tuaj yeem tsis tsuas yog txuag tus nqi ntawm cov neeg ua haujlwm, tab sis kuj coj tau yooj yim rau cov neeg siv.Siv cov xov tooj ntawm tes los hloov pauv cov ntawv tswj lub cev lossis daim npav daim npav sib nqus tuaj yeem txo cov nqi tsim khoom ntawm ob qho tib si rau qee qhov, thiab tib lub sijhawm pab txhawb cov neeg siv qhib thiab swipe cards, txhim kho qib ntawm automation rau qee qhov, txo. tus nqi ntiav cov neeg ua haujlwm muab daim npav thiab txhim kho kev pabcuam.

3. NFC daim ntawv thov
Daim ntawv thov ntawm NFC tag yog sau qee cov ntaub ntawv rau hauv NFC lossis, thiab tus neeg siv tuaj yeem tau txais cov ntaub ntawv cuam tshuam tam sim ntawd los ntawm tsuas yog swiping NFC lossis nrog NFC lub xov tooj ntawm tes.Piv txwv li, cov tub lag luam tuaj yeem tso NFC cim npe uas muaj cov ntawv tshaj tawm, cov ntaub ntawv tshaj tawm, thiab kev tshaj tawm ntawm lub qhov rooj ntawm lub khw.Cov neeg siv tuaj yeem siv NFC lub xov tooj ntawm tes kom tau txais cov ntaub ntawv cuam tshuam raws li lawv cov kev xav tau, thiab tuaj yeem nkag mus rau hauv kev tes hauj lwm sib tham los qhia cov ntsiab lus lossis yam zoo rau cov phooj ywg.Tam sim no, NFC cim npe tau siv dav hauv daim npav tuaj koom sijhawm, nkag mus rau cov npav tswj hwm thiab npav npav, thiab lwm yam, thiab cov ntaub ntawv NFC tag raug txheeb xyuas thiab nyeem los ntawm NFC nyeem ntawv tshwj xeeb.

Handheld-wirelesstau tsom mus rau kev txhim kho thiab tsim cov khoom siv IoT raws li RFID thev naus laus zis tau ntau xyoo, muab cov neeg siv khoom nrog cov khoom lag luam customized thiab cov kev pabcuam suav nrogRFID nyeem thiab sau cov khoom siv, NFC handsets,barcode scanners, biometric handhelds, electronic tags and related application software.
