Cov neeg yuav khoom tau nug tiag tiag thaum lawv tshawb nrhiav qhov no
Yuav luag tsis muaj leej twg tshawb nrhiav daim npav RFID thiab nyeem ntawv ua ke yog sim kawm seb RFID yog dab tsi. Lawv twb muaj qhov rooj, lawv twb muaj cov xauv, thiab feem ntau lawv twb muaj cov ntaub ntawv pov thawj hauv kev ncig. Qhov lawv xav paub yog qhov nqaim thiab kim dua kom tsis raug: puas yuav daim npav uas kuv tab tom xaj yuav qhib qhov rooj uas kuv twb muaj lawm, thiab kuv yuav ua li cas thiaj pom qhov ntawd ua ntej kev yuav khoom tawm?
Cov lus nug ntawd muaj cov lus teb tsis zoo hauv kev lag luam no. Ib qho kev ua tsis tau zoo tshaj plaws uas peb pom tsis yog ib qho kev puas tsuaj. Nws yog tus neeg yuav khoom uas tau hais tias cov khoom lag luam yog "universal," xaj tsib txhiab daim, thiab tshawb pom ntawm kev xa khoom uas tus nyeem ntawv tso tawm ib hom ntawv uas tus tswj hwm tsis lees txais, lossis qhov ntsuas ntsuas ntsuas qhov tseeb tiv thaiv daim npav cov ntaub ntawv cov ntawv tshiab yeej tsis tau encoded nrog. Daim npav ua haujlwm. Cov neeg nyeem ua haujlwm. Lub kaw lus tseem tsis qhib.
Qhov no yog sau rau tus neeg tuav daim ntawv xaj yuav khoom. Nws suav nrog qhov kev hloov pauv ntawm cov tsev so, tsev kawm ntawv, thiab cov chaw ua haujlwm hauv tsev kawm ntawv, qhov twg txhua qhov chaw so, thiab daim npav RFID thiab cov neeg nyeem ntawv txheeb xyuas qhov tsis sib xws thaum nws tseem pheej yig los kho.
Daim npav thiab tus nyeem ntawv yog ib qho kev txiav txim siab yuav khoom
Kho cov no raws li ob kab lus ntawm ib qho kev tsocai yog qhov uas feem ntau cov khoom yuam kev pib. Ib daim npav RFID thiab tus nyeem ntawv ua ke tsuas yog ua haujlwm thaum peb yam khoom sib txuas rau tib lub sijhawm, thiab ib qho ntawm lawv ua tsis tiav yuav siv tag nrho cov saw hlau.
Thawj qhov yog zaus, thiab 125 kHz vs 13.56 MHz daim npav thiab nyeem ntawv tsis sib haum yog ib hom tsis ua haujlwm uas koj tsis tuaj yeem ua haujlwm tom qab qhov tseeb. Tsawg- zaus thiab siab- cov ntawv pov thawj zaus yog lub cev tsis sib haum. Ib tug nyeem tuned rau ib tug yuav tsis pom lwm tus kiag li. Qhov thib ob yog chip tsev neeg thiab yuav ua li cas lub kaw lus authenticates. EM4200, T5577, MIFARE Classic, MIFARE Plus thiab MIFARE DESFire txhua tus nyob ntawm lawv tus kheej qib kev ruaj ntseg, thiab tus nyeem ntawv uas tuaj yeem tham nrog ib daim npav tsis zoo ib yam li tus tswj hwm uas yuav lees txais cov ntawv ntawd hais. Qhov thib peb yog raws tu qauv ntawm tus nyeem ntawv thiab tus maub los, uas yog qhov chaw Wiegand thiab OSDP zaum, thiab cov neeg yuav khoom feem ntau yeej tsis xav txog kom txog thaum cov lus tuaj txog.
Ntawm no yog ib feem uas daim ntawv spec yuav tsis qhia koj. Ob ntawm peb txheej yog txiav txim siab los ntawm cov khoom siv uas koj twb muaj lawm, tsis yog los ntawm qhov koj yuav tom ntej. Koj cov locks uas twb muaj lawm thiab cov tswj tau hais qhov zaus thiab, feem ntau, txoj kev lees paub. Qhov koj xaiv tiag tiag thaum koj tau txais daim npav RFID thiab cov ntawv nyeem yog cov khoom siv lub cev, qhov encoding, ua tiav, thiab tus neeg muag khoom, tsis yog cov thev naus laus zis. Cov neeg yuav khoom uas nkag siab qhov kev txwv thaum ntxov siv lawv lub zog sib tham hauv qhov chaw raug; cov neeg yuav khoom uas tsis siv nws sib cav txog chip specs uas tsis tau qhib rau lawv. Yog hais tias cov lus ntawm no tsis paub, cov ntaub ntawv pov thawj hauv qab no raug them cais hauv peb cov ntsiab lus ntawmRFID smart card yog dab tsi thiab nws khaws cov ntaub ntawv li cas.
Peb qhov chaw, Peb txoj kev sib txawv tib daim npav RFID thiab nyeem ntawv teeb tsa tsis tiav
Chaw ntiav pw, tsev kawm ntawv, thiab chaw ua haujlwm hauv tsev kawm ntawv tau hais ib yam nkaus, uas yog qhov yuam kev. Lub tshuab overlaps hnyav heev. Cov kev txwv tsis sib tshooj lawm, thiab cov lus hauv qab no yog cov lus qhia luv tshaj plaws ntawm kev ncaj ncees ntawm ib daim npav RFID thiab cov ntawv nyeem yuav tsum khoov rau txhua qhov chaw.
| RFID card thiab nyeem ntawv txwv | Tsev so | Cov tsev kawm ntawv | Cov tsev kawm ntawv lag luam |
|---|---|---|---|
| Thawj qhov txwv ntawm koj cov kev xaiv | Cov xauv tsis tuaj yeem hloov pauv ntau | Kev xa tawm ntim thiab nqi tsev | Ntau- site format tsis sib xws |
| Hom kev hloov pauv tshiab | Tsis tu ncua, txhua qhov kev txiav txim | Ib pawg loj rau kev noj, ntxiv rau kev hloov pauv txhua xyoo | Tsawg ntim, lub neej ntev daim ntawv pov thawj |
| Kev cia siab ruaj ntseg | Guest kev nyab xeeb thiab lav | Nruab nrab, tab sis kev ceev ntiag tug - tswj hwm | Siab tshaj; feem ntau audited |
| Tus nqi rhiab heev | Ntawm daim card, aggressively | Ib daim npav, ntxiv rau kev luam ntawv thiab tus kheej | Ib lub qhov rooj, tsis yog ib daim npav |
| Qhov twg nws feem ntau tawg | Legacy xauv firmware thiab encoders | Kev ua raws cai thiab xa rov qab logistics | Daim npav naj npawb chaw thiab hom kev sib tsoo |
Lub rooj ntawd yog luv luv version. Txhua kem nqa ib qho kev ua tsis tiav uas tsuas yog tshwm sim hauv qhov chaw tshwj xeeb, thiab tsis muaj ib qho ntawm peb pom los ntawm cov khoom lag luam catalogue. Tus so ntawm no npog txhua tus nyob rau hauv lem.
Chaw ntiav pw: Koj tab tom yuav ib ncig ntawm lub xauv koj hloov tsis tau
Lub ntsiab lus ntawm lub tsev so RFID daim npav thiab qhov project nyeem ntawv yog tias cov xauv tau raug teeb tsa, twb tau them rau, thiab tsis tuaj yeem tawm ntawm lub qhov rooj yam tsis muaj chav kaw. Txhua qhov kev txiav txim muab khoom khoov khoov ntawm qhov ntawd.
Dab tsi ua rau qhov nyuaj tiag tiag tam sim no yog qhov sib faib loj ntawm lub hauv paus nruab tau khiav ntawm cov cuab yeej pov thawj kev ruaj ntseg hauv zej zog kev tshawb fawb tsis pom zoo ntxiv lawm. Kev nthuav tawm Unsaflok hauv 2024 tau npog cov txheej txheem ntawm qhov tsis zoo hauv ib qho kev siv hluav taws xob kaw lus dav dav, cuam tshuam ntau dua peb lab lub xauv thoob thoob 131 lub teb chaws, qhov twg ib khub ntawm forged keycards tuaj yeem qhib txhua chav ntawm ib lub cuab yeej (Unsaflok tshawb fawb pab pawg). Qhov teeb meem cipher hauv qab yog laus dua li ntawd. MIFARE Classic's Crypto-1 tau tshaj tawm rau pej xeem hauv cov ntaub ntawv kawm tau zoo tshaj li kaum xyoo (arXiv).
Qhov tseeb xaus yog tsiv mus rau encrypted credentials. Ntawm no yog qhov uas cov lus xaus tsis yooj yim. Kev kho dua tshiab ntawm cov cuab yeej tsis yog daim npav yuav khoom: nws yog lub xauv firmware hloov tshiab lossis hloov pauv, tag nrho cov ntawv rov ua dua tshiab ntawm txhua daim npav hauv kev ncig, pem hauv ntej - lub rooj hloov kho software, cov encoders tshiab, thiab feem ntau rov ua haujlwm ntawm lub elevator, chaw nres tsheb, thiab kev them nyiaj sib koom ua ke uas tau khi rau daim ntawv pov thawj qub. Tias yog vim li cas, thaum lub sijhawm tshaj tawm xyoo 2024, tsuas yog kwv yees li ib feem peb ntawm cov xauv cuam tshuam tau raug kho.
Muaj ib qho kev kuaj mob tsim nyog paub ua ntej koj tham nrog leej twg, vim tias nws tsis raug nqi dab tsi thiab nws qhia koj qhov kev sib tham uas koj tau ua tiag tiag. Cov lus qhia tau tshaj tawm nrog rau qhov kev tshaj tawm tau piav qhia txog cov khoom kho dua tshiab raws li tau muab rov qab rau MIFARE Ultralight C es tsis yog MIFARE Classic, yog li cov nti hauv daim npav ntawm koj tus kheej lub rooj sab nraud yog qhov taw qhia tsis zoo ntawm seb lub cuab yeej cuab tam tom qab nws tau kov. Kho nws raws li kev nyeem thawj zaug es tsis yog pov thawj, tab sis cov cuab yeej tseem muab MIFARE Classic keycards qhia rau koj tias txhua daim npav RFID thiab cov neeg nyeem ntawv rau cov tsev so uas tau hais tawm tsam cov cuab yeej cuab tam yuav tsum tau teev tseg rau qib ua ntej - txhim kho tiam, txawm li cas los xij hauv phau ntawv qhia.
Qhov ntawd tawm ntawm txoj kev tsiv teb tsaws nws tus kheej, thiab muaj txoj hauv kev nrawm dua los tso koj tus kheej dua li nug tus neeg muag khoom xauv. Saib seb cov cuab yeej tam sim no muab daim npav li cas. Yog tias lub rooj sib tham pem hauv ntej sau cov ntaub ntawv pov thawj los ntawm lub network encoder thiab cov xauv tau txais kev hloov tshiab yam tsis muaj tus kws tshaj lij kov txhua lub qhov rooj, cov cuab yeej cuab tam yuav luag txhua lub sijhawm uas lees txais kev poob - hauv kev hloov pauv, thiab koj tab tom yuav daim npav. Yog tias daim npav tseem sau rau ntawm tus encoder standalone thiab txhua lub xauv yuav tsum tau mus xyuas ib tus zuj zus nrog tus neeg tuav tes programmer, tus maub los thiab xauv firmware sab yuav tsum txav mus ua ntej, thiab tsis muaj daim npav tshwj xeeb yuav tau txais koj nyob ntawd. Paub txog leej twg ntawm ob qho koj nyob hauv kev txiav txim siab seb koj puas tau txais daim npav RFID thiab tus nyeem ntawv uas sib haum nrog cov xauv uas twb muaj lawm, lossis ntsuas qhov project kho vajtse. Nws yog tsim nyog nyeem li cas lubtxawv daim npav technologies qab tsev so qhov rooj xauv qhov rooj ua haujlwm tauua ntej koj cog lus rau ib nti.
Cov Tsev Kawm Ntawv: Ntim, Tus Nqi Rov Qab, thiab qhov teeb meem pom zoo Tsis muaj leej twg them nyiaj rau
Lub tsev kawm ntawv thiab cheeb tsam tej yaam num muaj tus nqi sib txawv kiag li. Ib daim npav RFID hauv tsev kawm ntawv thiab cov neeg nyeem ntawv xa mus rau pem hauv ntej - thauj khoom ib qho loj heev ntawm kev noj, tom qab ntawd los ntshav hloov txhua xyoo raws li cov tub ntxhais kawm poob daim npav. Chav tsev tus nqi tseem ceeb tshaj li lwm ntu, thiab tus kheej xws li duab, npe, barcode thiab luam ntawv zoo yog feem ntau yuav tsum tau ua es tsis yog xaiv tau.
Kev sib koom ua ke yog cov ntaub ntawv zoo thiab muaj suab nrov: cov tsev kawm ntawv qib siab uas sib koom ua ke cov ntaub ntawv pov thawj sib thooj rau hauv ib daim npav hauv tsev kawm ntawv tau ua nws feem ntau los txiav kev tswj hwm nyiaj siv ua haujlwm, tsis yog vim cov thev naus laus zis xav tau. Ib daim npav pheej yig dua rau qhov teeb meem, pheej yig dua rau kev tshem tawm, thiab yooj yim dua rau cov neeg tuav daim npav kom taug qab. Tias yog vim li cas feem ntau RFID nkag mus tswj daim npav nyeem ntawv rau cov tsev kawm ntawv cov haujlwm sib koom ua ke ntawm ib daim ntawv pov thawj es tsis yog tsev neeg ntawm lawv.
Muaj qhov txwv thib ob ntawm no, txawm li cas los xij, thiab nws yog qhov uas xaus cov haujlwm es tsis ncua sijhawm rau lawv. Hauv Tebchaws Meskas, ntau lub xeev tau txwv lossis txwv yuav tsum tau RFID- taug qab cov tub ntxhais kawm ntawv ID. New Hampshire thiab Missouri tau dhau txoj cai tiv thaiv tsev kawm ntawv los ntawm kev xav tau daim npav ID nrog RFID taug qab muaj peev xwm, ua raws li txoj cai dhau los hauv Oregon thiab Rhode Island (Stateline). Lub ntsiab lus tseem ceeb yog ib cheeb tsam uas tau tshaj tawm RFID-pab tub kawm ntawv cov paib tsis tau qhia rau niam txiv kiag li.
Qhov no hloov kev nyeem ntau yam mus rau qhov sib txawv ntawm kev ua raws es tsis yog qhov ua tau zoo. Qhov ntev - daim ntawv pov thawj uas teev cov tub ntxhais kawm kev txav mus los yog qhov sib txawv raws cai los ntawm daim npav luv luv - cov tub ntxhais kawm txhob txwm kais ntawm lub voj voog, txawm tias cov nti sab hauv zoo ib yam. Nws tsim nyog txiav txim siab qhov twg ntawm ob yam uas koj tab tom yuav tiag tiag ua ntej koj luam tsib txhiab daim npav, vim tias kev luam ntawv yog qhov koj tsis tuaj yeem thim rov qab.
Muaj kev cuam tshuam kev cuab yeej. Rov qab- engineering ua hauj lwm nyob rau hauv ib lub tsev kawm ntawv daim ntawv pov thawj pom tau hais tias lub tsev kawm ntawv nkag mus rau hauv lub tsev kawm ntawv tau tso cai los ntawm daim npav UID nkaus xwb, tsis muaj kev txheeb xyuas cov ntaub ntawv khaws cia rau hauv daim npav txhua, uas ua rau cloning tsis tseem ceeb txawm hais tias lub nti zoo npaum li cas (arXiv). Daim npav tsis yog qhov tsis muaj zog. Qhov system configuration yog. UID- tsuas yog kev lees paub yog tiv thaiv rau lub tsev noj mov mus txog lossis lub tsev qiv ntawv lub rooj vag, qhov twg qhov tshwm sim tsis zoo yog noj su dawb, thiab tsis muaj kev tiv thaiv rau lub khw muag tshuaj, chav neeg rau zaub mov, lossis ib lub qhov rooj tom qab uas tus menyuam yaus tuaj yeem nyob ib leeg nrog qee yam txaus ntshai. Yog tias cov qhov rooj muaj nyob hauv koj qhov chaw thiab cov lus teb tseem yog UID- nkaus xwb, qhov kev hloov kho daim ntawv pov thawj tsis yog qhov kho; tus maub los configuration yog, thiab nws yuav tsum tshwm sim ua ntej. Kauj ruam ob ntawm qhov kev txheeb xyuas ib ntus txuas ntxiv mus yuav ua li cas kom tau txais cov lus teb ncaj qha tawm ntawm tus neeg koom ua ke ntawm qhov no, vim tias "nws txhawb nqa MIFARE" tsis yog lus teb rau lo lus nug.
Txawm hais tias koj xaj cov khoom lag luam dawb lossis daim npav tus kheej hloov pauv kev lag luam ntawm no tseem ceeb, uas peb tawg hauv peb qhov kev sib piv ntawmblank piv rau ua ntej - luam daim npav.
Corporate Campuses: Ntau -Site Is Where Card Formats Break
Cov chaw lag luam feem ntau muaj cov ntawv pov thawj tsawg tshaj plaws thiab qhov kev cia siab siab tshaj plaws, yog li cov neeg yuav khoom xav tias qhov no yog qeb yooj yim. Nws yog, txoj cai txog thaum lub koom haum qhib qhov chaw thib ob.
Qhov teeb meem yog naj npawb chaw. 26-ntsis Wiegand hom ntawv uas tseem txhawb nqa qhov loj heev ntawm kev teeb tsa kev tswj hwm tau faib 65,536 tus lej cim tshwj xeeb rau ib qho chaw, hla 256 qhov chaw lis dej num (IPVM). Qhov ntawd suab zoo li ntau txog thaum lub tuam txhab nrog ntau qhov chaw, txhua qhov kev txiav txim siab ntawm nws tus kheej los ntawm cov neeg muag khoom sib txawv ntau xyoo, xaus nrog ob tus neeg ua haujlwm tuav daim npav uas nthuav tawm cov ntaub ntawv zoo ib yam rau tus tswj hwm. Lub sijhawm ntawd, lub kaw lus tsis tawg: nws ua haujlwm raws nraim li tsim, thiab cia tus neeg tsis ncaj ncees los ntawm lub qhov rooj. Qhov no yog qhov laj thawj tiag tiag uas pheej yig cov khoom lag luam tsis muaj txiaj ntsig yog qhov txaus ntshai ntawm kev lag luam nplai, thiab nws yog vim li cas RFID daim npav thiab nyeem ntawv nthuav tawm rau cov chaw lag luam hauv tsev kawm ntawv xav tau lub hauv paus ntawm tus lej sau npe ua ntej nws xav tau kho vajtse zoo dua.
Qhov kev thov kho ib txwm yog ntau- thev naus laus zis nyeem ntawv uas lees txais ntau hom ntawv pov thawj ib zaug. Kuv txoj haujlwm ncaj ncees, thiab nws tsis yog ib tus neeg muag khoom feem ntau yuav muab rau koj: qhov no ua haujlwm tsis zoo hauv thaj teb dua li nws ua hauv daim ntawv teev cov ntaub ntawv. Cov koom ua ke tau tshaj tawm cov neeg nyeem tuav ob hom ntawv 26-ntsis ib txhij uas tsim dab nyeem (tus nyeem ntawv tig ntsuab thiab tso lub qhov rooj nrog tsis muaj leej twg tam sim no) thiab cov neeg nyeem kaw tag nrho tom qab cov neeg siv cov ntawv cim alternating cov ntaub ntawv pov thawj, rov qab tau tsuas yog los ntawm kev txiav fais fab (IPVM). Multi- thev naus laus zis kho vajtse yog cov cuab yeej hloov pauv nrog lub hnub kawg uas tau hais tseg, tsis yog kev tsim kho mus tas li.
Qhov twg hnub kawg yuav tsum zaum yog qhov sib txawv tsis muaj leej twg hais txog. Nws tsis yog teem los ntawm tus nyeem ntawv lub warranty. Nws yog teem los ntawm qhov twg khiav tawm ua ntej: koj cov lej uas tsis tau muab tso rau hauv cov ntawv qub qub, lossis lub neej kev pabcuam ntawm cov tswj uas tseem tsuas yog hais lus. Khiav ob tus lej ua ntej koj yuav cov khoom siv txuas txuas, vim tias tus nyeem ntawv ntau - thev naus laus zis tau yuav yam tsis muaj qhov kev suav ntawd yuav dhau los ua qhov qub. Cov chaw tseem tab tom khiav qis-frequency procedentials credentials will find the constraints in our breaks of125 kHz EM daim npav kev ruaj ntseg thiab txhim kho txoj hauv kev.
Ib qho kev txiav txim qauv tsim nyog qiv los ntawm cov neeg koom ua ke: tus tswv lag luam platform peb muab rau hauv cov neeg Ixayees siv kwv yees li ob lab daim npav ib xyoos hla ib qho huab - tswj kev nkag mus thiab tsis muaj nyiaj ntsuab, thiab txiav txim tawm tsam ib qho kev siv encoding ruaj khov dua li ntawm ib qhov chaw. Qhov ntawd tsis yog qhov ntim feem ntau cov tuam txhab hauv tsev kawm ntawv yuav mus txog. Kev qhuab qhia tom qab nws yog qhov tseem ceeb, thiab nws hloov mus ncaj qha: ib daim npav RFID thiab nyeem ntawv siv, ib tus neeg muag khoom, ib tus lej sau npe nres qhov kev sib tsoo uas tau piav qhia saum toj no, thiab nws ua haujlwm ntawm tsib txhiab daim npav nrog rau ntawm ob lab.
Wiegand lossis OSDP: Cov Kab Nyiaj Txiag uas tshwm sim lig
Qhov no yog qhov sib txawv uas ua rau cov neeg xav tsis thoob nruab nrab ntawm - project. Wiegand yog ib qho -txoj kev, tsis muaj kev sib txuas ntawm tus nyeem ntawv thiab tus tswj hwm uas tau ua haujlwm rau ntau xyoo lawm. OSDP yog tus encrypted, ob-txoj kev, saib xyuas kev hloov pauv tsim los ntawm Security Industry Association, tau pom zoo los ntawm International Electrotechnical Commission hauv 2020 thiab luam tawm raws li IEC 60839-11-5, nqa AES-128 encryption thiab saib xyuas cov cuab yeej siv sijhawm tiag tiag (Kev ruaj ntseg Industry Association).
Cov neeg yuav khoom hnov "cov txheej txheem encrypted" thiab xav tias qhov kev hloov pauv uas lawv xav tau. Tsis yog. Cov txheej txheem tswj hwm tus nyeem ntawv - mus rau - tswj txuas; daim npav tseem raug xaiv los ntawm txawm koj qhov system authenticates tawm tsam. Qhov nws hloov pauv yog cov neeg nyeem thiab cov tswj hwm koj tuaj yeem siv, thiab qhov ntawd yog qhov nyiaj.
Cov xwm txheej feem ntau cov lus hais tawm tawm: hloov cov neeg nyeem nrog OSDP- cov cuab yeej muaj peev xwm thaum tus tswj hwm nyob ntawm Wiegand yuav luag tsis muaj dab tsi rau koj. Lub encryption tsuas yog muaj thaum ob qho tib si xaus lus.
Tab sis qhov kev txiav txim ntawd tig mus rau hauv ob qho xwm txheej. Thawj zaug yog thaum hloov tus maub los tau txais nyiaj thiab teem sijhawm, qhov twg yuav OSDP- cov neeg nyeem muaj peev xwm tam sim no zam kev them nyiaj rau tib lub qhov rooj ob zaug. Qhov thib ob yog thaum koj cov neeg nyeem uas twb muaj lawm tsuas yog thaum kawg ntawm lub neej; Yog tias koj tab tom hloov kho qhov kho vajtse lawm, OSDP tus nqi qis yog qhov tsis zoo thiab tsis kam lees nws kaw koj mus rau lwm xyoo kaum ntawm cov ntawv dawb. Sab nraum ob qhov xwm txheej no, nyeem ntawv- thawj qhov kev tsiv teb tsaws chaw yog kev them nyiaj rau qhov tshwj xeeb uas tsis hloov pauv. Lub sijhawm yog lwm ib nrab ntawm qhov no. Kev ruaj ntseg microcontroller mov txwv tau thawb cov nyeem ntawv coj mus rau ib ncig ntawm kaum rau lub lis piam nrog tus nqi nce hauv 3.5 txog 15 feem pua (Mordor txawj ntse), thaum daim npav tsis nqa lub sijhawm ua haujlwm. Kev txiav txim ob feem ntawm daim npav RFID thiab tus nyeem ntawv tshwj xeeb ntawm tib lub sijhawm yog li cas cov phiaj xwm plam, thiab nws yog vim li cas peb daim npav thiabnyeem ntawv kho vajtsenyob rau nyias qhov rais xa khoom es tsis yog ib qho.
Daim npav RFID thiab nyeem ntawv pov thawj ib ntus peb siv ua ntej ntau lawm
Txhua phau ntawv qhia qhia koj kom paub meej tias kev sib raug zoo. Yuav luag tsis muaj leej twg qhia koj li cas. Qhov no yog ib ntus uas peb khiav nrog cov neeg siv khoom ua ntej daim npav RFID kev cai thiab tus nyeem ntawv xaj mus rau hauv ntau lawm, thiab thawj ob kauj ruam koj tuaj yeem ua tiav koj tus kheej hnub no.
- Qhia qhov koj twb muaj lawm.Tus neeg nyeem ntau- raws tu qauv yuav tshaj tawm cov zaus thiab nti tsev neeg ncaj qha, uas yog txoj hauv kev nrawm tshaj plaws los tsim kom tau daim npav RFID thiab nyeem ntawv koj qhov chaw ua haujlwm tiag tiag. Yog tsis muaj ib qho, NFC- lub xov tooj muaj peev xwm khiav NXP's TagInfo daim ntawv thov yuav txheeb xyuas feem ntau 13.56 MHz daim ntawv pov thawj hauv qab ib feeb.
- Paub meej tias tus maub los validates dab tsi.Nug koj tus neeg koom ua ke ib lo lus nug hauv daim ntawv qhia tseeb no: puas yog lub vaj huam sib luag txiav txim siab ntawm UID ib leeg, lossis ntawm cov ntaub ntawv encrypted nyeem tawm ntawm daim npav nco? "Nws txhawb MIFARE" teb ib lo lus nug txawv. Yog tias tsis muaj leej twg ntawm qhov chaw tuaj yeem teb tau, tus neeg koom ua ke cov ntaub ntawv sau npe ua haujlwm yuav qhia nws, thiab qhov kev thov no tsim nyog los sau ntawv.
- Xyuas cov hom ntawv thiab tus lej ntau.Tsim cov qauv me me, cov cai hauv chaw siv, thiab cov lej twg twb tau muab tawm thoob plaws txhua qhov chaw hauv lub koom haum.
- Ntsuas lub cev qauv tiv thaiv lub qhov rooj tiag.Tsis yog ib lub rooj ntev zaum, tsis yog lub desktop encoder: lub xauv tiag tiag, nyob rau hauv qhov chaw tiag tiag, nrog tus maub los tiag.
- Xauv qhov kev siv ntau lawm.Thaum ib qho piv txwv dhau, qhov kev teeb tsa tiag tiag dhau los ua qhov kev siv rau kev ua haujlwm tag nrho, nrog cov khoom sib xws tau lees paub tawm tsam nws tsis yog tawm tsam cov ntawv sau.
Cov kauj ruam plaub thiab tsib yog qhov chaw muab khoom cais, thiab lawv kuj yog ob kauj ruam uas koj tsis tuaj yeem ua tiav ib leeg. Peb thov kom cov neeg siv khoom xa peb daim npav uas twb muaj lawm kom peb tuaj yeem txheeb xyuas cov nti thiab xa rov qab cov qauv sib tw ua ntej leej twg cog lus rau ntim, uas txav qhov kev pheej hmoo mus rau lub Hoobkas, qhov twg nws nyob.
