Cov ntsiab lus tseem ceeb ntawm daim npav tswj kev nkag Tus thawj tswj kev nkag tau ntse muaj xws li tus tswv tsev, tus nyeem ntawv daim npav thiab lub xauv hluav taws xob (ntxiv lub khoos phis tawj thiab kev sib txuas lus thaum txuas nrog lub network).Daim npav nyeem ntawv yog ib txoj kev nyeem daim npav tsis sib cuag, thiab tus neeg tuav daim npav tsuas yog muab daim npav tso rau hauv tus nyeem ntawv Lub Mifare daim npav nyeem ntawv tuaj yeem nkag siab tias muaj daim npav thiab coj cov ntaub ntawv (daim npav) hauv daim npav mus rau tus tswv tsev.Tus tswv tsev thawj zaug kuaj xyuas qhov tsis raug cai ntawm daim npav, thiab tom qab ntawd txiav txim siab seb puas yuav kaw qhov rooj.Tag nrho cov txheej txheem tuaj yeem ua tiav kev tswj hwm kev tswj hwm kev ua haujlwm ntev npaum li lawv nyob hauv qhov kev siv tau ntawm daim npav swiping.Daim npav nyeem ntawv tau nruab rau hauv phab ntsa ntawm ib sab ntawm lub qhov rooj, uas tsis cuam tshuam rau lwm yam haujlwm.Thiab los ntawm kev sib txuas lus adapter (RS485) thiab lub khoos phis tawj rau kev saib xyuas lub sijhawm tiag tiag (txhua lub qhov rooj tuaj yeem qhib / kaw los ntawm lub khoos phis tawj cov lus txib, thiab cov xwm txheej ntawm txhua lub qhov rooj tuaj yeem pom hauv lub sijhawm), cov ntaub ntawv daws teeb meem, nug, qhia tawm tswv yim, lwm.

Covdaim npav nkagyog daim npav siv hauv kev tswj kev nkag mus, xws li pass, nkag mus, daim npav nres tsheb, daim npav ua tswv cuab, thiab lwm yam;ua ntej daim npav nkag mus rau tus neeg siv kawg, nws tau teeb tsa los ntawm tus thawj tswj hwm los txiav txim siab thaj chaw siv tau thiab cov neeg siv txoj cai, thiab tus neeg siv tuaj yeem siv tau.nkag mus tswj daim npavyog swiped kom nkag mus rau hauv cheeb tsam tswj, thiab cov neeg siv uas tsis muaj daim npav tswj xyuas lossis tsis tau tso cai tsis tuaj yeem nkag mus rau thaj chaw tswj hwm.

Nrog rau kev ntxiv dag zog rau kev tswj hwm kev lag luam, kev tswj cov qauv raws li kev siv daim npav tau dhau los ua ntau dua.Daim npav barcode, daim npav hlau nplaum sib nqus, thiab daim npav tiv tauj ID, raws li cov ntaub ntawv ntawm kev saib xyuas, kev tswj xyuas, kev siv nyiaj, chaw nres tsheb, kev tswj lub club, thiab lwm yam, ua lawv lub luag haujlwm tshwj xeeb sab nraum kev tswj hwm cov zej zog ntse.Txawm li cas los xij, raws li kev ua haujlwm ntawm kev tswj hwm daim npav tau nyob ruaj khov, vim tias cov kev txwv ntawm kev ua haujlwm ntawm daim npav tsis tuaj yeem ua tau raws li qhov xav tau ntawm daim npav tag nrho, nws yog qhov yuav tsum tau ntxiv daim npav rau tus tswv ib ntus kom tau raws li qhov xav tau ntawm daim npav. kev tswj cov khoom ntiag tug, xws li nkag mus rau daim npav, daim npav ntau lawm, daim npav tswj kev nkag, daim npav nres tsheb, daim npav ua tswv cuab, thiab lwm yam, tsis yog tsuas yog nce nqi tswj hwm, tab sis kuj ua rau muaj kev nyuaj rau txhua tus tswv los tswj txhua tus phaib, qee zaum txawm tias "ntau daim npav" ntau dhau. .Yog li ntawd, nyob rau theem-tawm, tom qab 2010, mainstream card hom yuav tsum Nws belongs rauMifaredaim npav, tab sis txoj kev loj hlob ntawm daim npav CPU kuj ceev heev, uas yog ib qho qauv.Mifare card thiab nkag mus Tswj RFID Key chains muaj ntau yam kev siv.Ntawm ib sab, nws txoj kev ruaj ntseg yog siab;ntawm qhov tod tes, nws coj kev yooj yim rau tag nrho-hauv-ib daim npav.Teb, noj, tuaj koom, saib xyuas, ntse channel, thiab lwm yam yog kev koom ua ke rau hauv ib qho system, thiab kev ua haujlwm ntawm daim npav tag nrho tuaj yeem ua tiav yam tsis muaj kev sib tham.

Lub hauv paus ntsiab lus yog vim muaj ib nti hu ua RFID sab hauv.Thaum peb hla daim npav nyeem ntawv nrog daim npav uas muaj RFID nti, cov hluav taws xob hluav taws xob tawm los ntawm daim npav nyeem ntawv yuav pib nyeem cov ntaub ntawv hauv daim npav.Cov ntaub ntawv sab hauv tsis yog tsuas yog nyeem tau, thiab nws tuaj yeem sau thiab hloov kho.Yog li ntawd, daim npav chip tsis yog ib qho tseem ceeb xwb, tab sis kuj yog daim npav ID hauv hluav taws xob lossis nkag mus TswjRFID Key Chains.

Vim tias ntev npaum li koj sau koj tus kheej cov ntaub ntawv hauv lub nti, koj tuaj yeem paub leej twg nkag mus thiab tawm ntawm daim npav nyeem ntawv.
Tib thev naus laus zis kuj tseem siv los tiv thaiv tub sab hauv cov khw muag khoom thiab lwm yam.

Muaj ntau ntau hom ntawv tswj kev nkag, uas tuaj yeem muab faib ua ob peb pawg raws li cov ntaub ntawv xaiv.Piv txwv ntawm kev faib tawm ntawm cov ntawv tswj kev nkag tiav tiav:
Raws li cov duab
Raws li cov duab, nws tau muab faib ua cov ntawv teev lus thiab cov ntawv tshwj xeeb-puab.Daim npav tus qauv yog cov khoom lag luam loj loj thoob ntiaj teb, thiab nws qhov loj yog 85.5mm × 54mm × 0.76mm.Niaj hnub no, kev luam ntawv tsis txwv los ntawm qhov loj me vim yog kev xav tau ntawm tus kheej, uas tau ua rau pom ntau daim npav "weird" ntawm txhua yam hauv lub tebchaws thoob plaws ntiaj teb.Peb hu rau hom ntawv tshwj xeeb-zoo li daim npav no.
Los ntawm daim npav
a) Magnetic card (ID card): Qhov zoo dua yog tus nqi qis;ib daim npav rau ib tus neeg, kev ruaj ntseg dav dav, tuaj yeem txuas nrog lub computer, thiab muaj cov ntaub ntawv qhib qhov rooj.Qhov tsis zoo yog daim npav, cov khoom siv hnav, thiab lub neej luv luv;daim npav yog yooj yim luam;nws tsis yooj yim los tswj ob txoj kev.Cov ntaub ntawv daim npav tau yooj yim ploj vim yog sab nraud sib nqus, ua rau daim npav tsis raug.
b) Xov tooj cua zaus daim npav (IC daim npav): Qhov zoo dua yog tias daim npav tsis muaj kev sib cuag nrog lub cuab yeej, qhib lub qhov rooj yooj yim thiab nyab xeeb;lub neej ntev, cov ntaub ntawv theoretical tsawg kawg yog kaum xyoo;kev ruaj ntseg siab, tuaj yeem txuas nrog lub computer, nrog cov ntaub ntawv qhib qhov rooj;tuaj yeem ua tiav ob txoj kev tswj;daim card nyuaj yog theej.Qhov tsis zoo yog tias tus nqi siab dua.
Raws li kev nyeem ntawv nyob deb
1. Tiv tauj-hom nkag mus tswj daim npav, daim npav tswj kev nkag yuav tsum nyob rau hauv kev sib cuag nrog tus neeg saib xyuas daim npav nkag mus kom tiav cov haujlwm.
2, Inductive nkag mus tswj daim npav, daim npav tswj kev nkag tuaj yeem ua tiav txoj haujlwm ntawm swiping daim npav nyob rau hauv qhov kev nkag siab ntawm kev nkag mus tswj.

Daim npav tswj kev nkag mus yog feem ntau ntawm cov ntawv teev lus hauv qab no: EM4200 daim npav, Kev Tswj Xyuas RFID

Keyfobs, Mifare card, TM card, CPU card thiab lwm yam.Tam sim no, EM 4200 phaib thiab Mifare phaib tuav yuav luag tag nrho cov kev tswj xyuas daim ntawv thov kev lag luam.Yog li ntawd, thaum peb xaiv daim ntawv thov, nws yog qhov zoo tshaj plaws xaiv EM daim npav lossis Mifare daim npav ua peb daim npav tseem ceeb.Vim hais tias rau lwm daim npav uas tsis yog siv ntau, txawm tias nws yog kev loj hlob ntawm cov cuab yeej siv los yog kev sib txuam ntawm cov khoom siv, nws yuav ua rau peb muaj teeb meem ntau.Thiab nrog kev sib koom ua lag luam poob qis, cov ntawv teev lus no yuav tsis yooj yim thim tawm ntawm peb cov ntawv thov kev lag luam tom qab lub sijhawm.Hauv qhov no, kev kho, kev nthuav dav, thiab kev hloov pauv ntawm kev tswj xyuas kev nkag mus yuav ua rau muaj teeb meem tsis txaus ntseeg.
Qhov tseeb, rau daim ntawv thov kev tswj xyuas kev nkag mus zoo tib yam, daim npav EM yog qhov ua tau zoo tshaj plaws ntawm daim npav tswj kev nkag.Nws yog tus cwj pwm los ntawm daim npav nyeem ntawv ntev, kev sib koom ua lag luam siab, thiab kev xyaum ua haujlwm zoo.Tab sis qhov tsis zoo tshaj plaws ntawm hom ntawv no yog tias nws tsuas yog daim npav nyeem nkaus xwb.Yog tias peb nyob ntawm lub rooj vag thiab xav tau qee qhov kev them nyiaj lossis kev ua haujlwm, ces daim npav zoo li no yeej tsis muaj zog me ntsis.
Rau cov neeg siv uas xav tau kev tswj hwm kev noj haus, yog tias xav tau qee cov ntaub ntawv yooj yim lossis hloov pauv, ces daim npav Mifare txaus.Tau kawg, yog tias peb tseem xav tau qee cov ntsiab lus ntxaws ntxiv lossis kev ua lag luam hauv daim ntawv thov kev nkag mus rau kev tswj hwm, ces CPU daim npav txhawb nqa los ntawm cov thev naus laus zis tshiab muaj kev ruaj ntseg dua li daim npav Mifare ib txwm.Nyob rau lub sijhawm ntev, CPU phaib tau nce zuj zus ntawm Mifare daim npav lag luam.
