Tso lus
Ib tug duplicator beeps thiab qhov screen haissau ua tiav. Daim ntawv nplaum mus rau tom qab ntawm lub xov tooj. Ntawm lub qhov rooj, tus nyeem ntawv tsis ua dab tsi: tsis muaj beep, tsis muaj LED, tsis muaj log nkag. Tus neeg siv khoom tau sawv ntawm qhov khoom nrog cov khoom uas tau kuaj zoo kaum feeb dhau los.
Qhov no yog daim pib kev txhawb nqa ntau tshaj plaws uas peb tau txais los ntawm cov neeg yuav khoom uas rov muag dua, thiab yuav luag txhua qhov teeb meem lub tshuab luam ntawv tau ua raws nraim li nws yuav tsum ua. Yog li cov lus nug muaj txiaj ntsig txog clone RFID daim nplaum tsis yog qhov kev sau ua haujlwm. Nws yog dab tsi ntxiv yuav tsum muaj tseeb rau qhov sau ntawv kom ciaj sia txoj kev mus los ntawm lub rooj ntev zaum mus rau lub qhov rooj.
Tus neeg nqa khoom nyias nyias tsis muaj leej twg nyeem cov ntaub ntawv ntawm
Tshem tawm ntawm kev lag luam thiab cov ntawv sau rov qab RFID 125kHz cov khoom lag luam yog ib yam: ib daim ntawv sau tau thiab nws cov kav hlau txais xov laminated rau hauv cov nplaum -backed disc, feem ntau 25, 30, los yog 40 hli thoob plaws thiab nyob ib ncig ntawm 0.9 hli tuab, nrog kev ua haujlwm ntawm kwv yees li 1-10 cm. Qhov tsawg- zaus versions nqa T5577 lossis EM4305 nti ntsuas rau ntau tshaj 100,000 sau lub voj voog thiab tshaj kaum xyoo ntawm cov ntaub ntawv khaws cia. Cov naj npawb no tshwm sim hauv txhua daim ntawv teev npe, thiab lawv muaj tiag.
Dab tsi cov npe yeej tsis cais yog qhov txawv ntawm adaim ntawv nplaum sau tau dawbthiab adaim ntawv tiav. Ib qho dawb paug T5577 clone RFID daim nplaum tawm ntawm lub Hoobkas tsis muaj daim npav naj npawb hauv nws. Muab nws rau lub qhov rooj xauv thiab tsis muaj dab tsi tshwm sim, vim tias tsis muaj ntaub ntawv pov thawj los muab tau. Nws yuav tsum tau sau ua ntej nrog tus kws sau ntawv 125 kHz. Nov yog ib qho ntawm peb feem ntau pom thaum tus neeg siv khoom xa rov qab cov ntawv nplaum rov qab rau peb rau kev tshuaj xyuas.
Yog li lub cev spec ntawm daim ntawv qhia koj yuav luag tsis muaj dab tsi txog seb puas yuav ua haujlwm hauv thaj chaw. Txhua yam uas txiav txim siab uas zaum hauv lub nti coj tus cwj pwm li cas, thiab nyob rau hauv dab tsi daim ntawv nplaum cov duab ua rau thaj teb nws nyob ntawm.
Ob zaus, Ob lub ntsiab lus sib txawv ntawm "Sau"
Lo lusclonezais qhov tseeb tias muaj ob txoj hauv kev tsis sib haum xeeb hauv qab nws, thiab qhov tsis meej pem lawv yog qhov chaw muab khoom ua ntej.
Tsawg- zaus 125 kHz cov ntaub ntawv pov thawj, lub ntsiab lus EM4100 / TK4100 tsev neeg uas muaj nyob hauv kev tswj hwm kev nkag mus tau zoo, tau muab luam tawm los ntawm kev sau tus ID tshiab rau hauv T5577 lossis EM4305 nti kom nws nthuav tawm tus thawj tus kheej. Siab - zaus 13.56 MHz daim ntawv pov thawj raws li MIFARE Classic ua haujlwm txawv. Tus cim tshwj xeeb nyob hauv block 0, uas ntawm tus qauv nti tau nyeem- nkaus xwb, yog li yuav tsum muaj daim ntawv nplaum UID hloov tau RFID ua ntej luam tawm txhua qhov. Cov lus txib tau teeb tsa ob tsev neeg no cov lus teb rau cov ntaub ntawv nthuav dav los ntawm kev qhib- qhov chaw tshawb fawb zej zog uas tswj hwm Proxmark tooling (RfidResearchGroup), thiab HF huab cua interface nws tus kheej tau txhais hauv ISO / IEC 14443.
Rau tus neeg yuav khoom txhais lus luv luv: qhov zaus yuav tsum phim tus nyeem ntawv ua ntej lwm cov lus nug tseem ceeb.
Cov kab lus ntawd muaj tseeb thiab nws kuj yog qhov uas tib neeg feem ntau nres, uas yog vim li cas thiaj li muaj ntau pawg tseem ua tsis tau tom qab kuaj xyuas ntau zaus. Sib piv qhov zaus tsuas yog tau daim ntawv nplaum rau hauv kev sib tham. Txawm hais tias tus nyeem ntawv lees txais qhov nws hnov tom ntej yog nyob ntawm lub nti cov lus teb cov yam ntxwv, thiab qhov ntawd yog cov lim cais, siv los ntawm kho vajtse koj tsis tswj. Yog hais tias lub hom phiaj system khiav ntawm 13.56 MHz, UID- hom ntawv thiab nyeem ntawv -cov lus nug coj tus cwj pwm tsim nyog ua haujlwm los ntawm lawv tus kheej ua ntej cov qauv raug txiav (MIFARE-cov ntaub ntawv sau npe hauv chav kawm).
Chip Generation teeb meem feem ntau cov neeg muag khoom yuav tsis tsa
Ntawm no yog qhov sib txawv uas txiav txim siab seb lub cloneable RFID daim nplaum daim ntawv xaj khiav ntsiag to lossis hloov mus rau hauv ib qho kev txhawb nqa mus tas li, thiab nws tsis tshua muaj tshwm sim ntawm daim ntawv spec txhua: lub cim "magic" ntawm HF nti.
Kev sib xyaw cov khawv koob-chip tiam hauv ib qho khoom xa tuaj yog txoj hauv kev nrawm tshaj plaws los rhuav tshem kev ua haujlwm duplicate cov cuab yeej.
Gen1a chips xav tau qhov tshwj xeeb backdoor wake- hais kom ua ua ntej thaiv 0 tuaj yeem sau dua. Gen2 chips yog ncaj qha-sau thiab lees txais cov lus txib sau ntawv uas tsis muaj qhov tshwj xeeb. Ib - sij hawm- sau cov chav kawm xws li FUID nres teb cov lus txib rov qab tom qab thawj qhov thaiv 0 kho, uas kaw cov ntawv mus tas li. Xa ib tus neeg siv khoom 5,000 daim qhov twg 3,000 yog Gen1a thiab 2,000 yog Gen2, thiab yog tias lawv qhov chaw nres tsheb programming tsuas yog teeb meem tom qab, qhov Gen2 feem yog seem ntawm tuaj txog: tsis muaj teeb meem, tsuas yog unprogrammable nrog cov khoom lawv muaj. Qhov ntawd yog tsib -daim duab sau- tawm los ntawm kab ntawm kev yuav khoom uas tsis muaj leej twg sau.
| Chip chav kawm | Thaiv 0 sau txoj kev | Re- sau tau tom qab thawj daim ntawv luam | Tus neeg yuav khoom haum |
|---|---|---|---|
| Gen1a khawv koob | Backdoor wake-up command | Yog, pheej rov qab | Cov neeg ua haujlwm nrog Proxmark- cov cuab yeej hauv chav kawm |
| Gen2 khawv koob | Direct sau, tus qauv hais kom ua | Yog, pheej rov qab | Cov cuab yeej sib xyaw ua ke, Android- raws li kev ua haujlwm |
| FUID / ib - sijhawm | Backdoor, thawj hloov xwb | Tsis yog, xauv tom qab sau thawj zaug | Cov kev pabcuam uas yuav tsum tiv thaiv rov-cloning downstream |
Muaj qhov thib ob, qeeb qeeb hom tsim nyog paub txog. Cov khoom siv khawv koob thaum ntxov muaj qhov tsis txaus ntseeg hauv lawv li cas lawv ua haujlwm luv luv ncua hauv ISO 14443-2 lub sijhawm. Daim npav tiag tiag yuav nres qhov twg qee daim npav ua khawv koob yuav nqa mus, thiab cov neeg nyeem tau hloov kho tom qab nrog cov ntxaij lim dej uas tus ntiv tes xoo raws nraim tus cwj pwm, uas thaum kawg thawb cov chips tawm ntawm kev tsim khoom. Rau ib tus neeg muag khoom, qhov tshwm sim tuaj txog lig: cloneable RFID sticker batch uas dhau txhua qhov kev xeem niaj hnub no tuaj yeem tsis lees paub los ntawm tus nyeem ntawv firmware-hloov kho tshiab kaum yim hli tom qab, ntev tom qab daim ntawv them nqi tshem tawm.
Tsis muaj ib tus neeg muag khoom tuaj yeem cog lus rau tus nyeem ntawv cov chaw tsim khoom yav tom ntej firmware tus cwj pwm, thiab leej twg ua tau twv. Qhov koj tuaj yeem ua tau yog kev cog lus ntau dua li kev tshaj lij, thiab nws los rau plaub yam. Txhim kho tus naj npawb ntawm nti hauv PO es tsis txhob lees txais "MIFARE-tshaj". Xav tau ntau tus lej luam tawm lossis sau rau ib lub thawv, yog li cov teeb meem batch tuaj yeem raug cais tawm es tsis txhob rov qab rov qab rau ib xyoos ntawm cov zis. Khaws cov qauv kaw los ntawm txhua qhov ntawm ob sab. Thiab pom zoo ua ntej leej twg rov- kuaj thiab leej twg absorbs tus nqi yog tias tus neeg siv khoom tus neeg nyeem ntawv hloov pauv mid- daim ntawv cog lus. Tsis muaj leej twg yog kab txawv. Nws yog tus qauv kev coj ua hauv txhua qhov kev tswj hwm cov khoom siv, thiab nws yog qhov sib cais qhov xwm txheej tshwm sim los ntawm kev sib cav. Cov tsev neeg nti tom qab cov kev txiav txim siab no yog tib yam pebtsim duplication- qib fobs thiab cov ntawv nplaum nyob ib puag ncig, uas yog vim li cas tus lej feem belongs rau qhov kev txiav txim es tsis yog hauv kev sib tham muag khoom.
Ib lub ntxiab me me zaum hauv cov kauj ruam sau nws tus kheej. Cov byte tom qab UID yog BCC checksum, XOR ntawm plaub UID bytes, thiab sau tus nqi tsis raug muag -bricks lub nti. Ntawm qhov siab - ntim kab uas tsaws ncaj qha rau hauv cov khoom seem, uas yog ib qho laj thawj ntxiv rau kev sib koom ua ke yog cov lus nug tsim khoom ntau dua li muaj hmoo.
Vim li cas tib lub Clone RFID Sticker nyeem ntawm Cardboard thiab tuag ntawm lub xov tooj
Kev lag luam cwj pwm hais tias daim ntawv nplaum yog ib daim ntawv nplaum thiab tsuas yog qhov sib txawv yog txoj kab uas hla thiab nplaum. Qhov tsis meej pem tshaj plaws hauv cov khoom lag luam no hais tias lwm yam. Tshem cov ntawv nplaum ua haujlwm tawm ntawm lub thawv, muab tso rau sab nraum qab ntawm lub xov tooj ntawm tes lossis rau ntawm lub qhov rooj hlau, thiab qhov ntau yuav poob los yog ploj mus. Lub chip zoo. Lub physics hloov.
Ntawm 125 kHz daim ntawv nplaum tsis tawg hauv qhov muaj txiaj ntsig zoo. Nws yog ib qho sib nqus coupling coil, thiab txhua yam nyob ntawm cov dej ntws los ntawm nws kom huv si. Hlau nyob ze absorbs lub zog los ntawm eddy tam sim no thiab hloov lub coil lub inductance, rub nws resonant point deb ntawm qhov chaw nyeem ntawv mloog. High-Q tags raug kev txom nyem feem ntau los ntawm qhov kev hloov ntawd, vim qhov kev hloov pauv txoj haujlwm nqaim txhais tau tias me me detune raug nqi ntau ntawm lub zog tau txais. Kev taw qhia tseem ceeb rau tib lub laj thawj: kev sib txuas yog qhov zoo tshaj plaws thaum daim ntawv nplaum lub coil zaum sib npaug rau tus nyeem ntawv kauj thiab ntog tawm mus rau 90 degrees (EDN). Lub xov tooj yog ib qho nyuaj dua li cov ntawv hlau, vim hais tias nyob rau sab saum toj ntawm lub roj teeb tiv thaiv nws stacks ib tug NFC kav hlau txais xov thiab, nce, ib tug wireless- charging coil rau tib ob peb square centimeters. Cov kws kho mob uas mount cov no nyob rau hauv xov tooj cov ntaub ntawv piav qhia txog lub kav hlau txais xov txheej nws tus kheej li 0.4 hli, tab sis cov pawg sib dhos, nrog foam spacer, ncav cuag ib ncig ntawm 3 hli ua ntej nws nyeem tau ntseeg tau, thiab cov hauj lwm tiag tiag yog nrhiav kom huv si ntawm lub xov tooj lub cev (Elektroda). Hauv kev xyaum, qhov chaw nruab nrab ntawm lub pob roj teeb yog ze rau qhov tsis muaj kev cia siab, thiab cov chaw ua haujlwm tau zaum ntawm ntug ntawm lub tsev, tshem tawm ntawm lub coil coil hneev taw.
Qhov kho yog txheej txheej ferrite cais ntawm daim nplaum thiab hlau, uas rov qab siv tau ntau yam los ntawm kev ua kom cov dej ntws tawm ntawm cov khoom siv hluav taws xob. Tab sis ib qho kev tiv thaiv hlau RFID daim nplaum nkag mus tswj kev xa tawm tseem xav tau kev txiav txim siab tsis yog lub thawv kos, thiab ciam teb yog qhov no. Yog hais tias lub hom phiaj nyeem nyob deb yog luv luv, lub ntsiab lus ntawm phab ntsa nyeem tus neeg siv kais ncaj qha, repositioning ib leeg feem ntau rov qab txaus ntau yam tsis muaj ferrite txhua. Yog tias daim ntawv nplaum yuav tsum tau ua haujlwm hla lub roj teeb tag nrho lossis lub qhov rooj steel, ferrite tsis yog xaiv tau thiab cov thickness tseem ceeb. Cov khoom lag luam xws li Laird luam tawm cov qauv ntawv tuab ntawm 0.05, 0.1 thiab 0.2 hli rau cov chav kawm ntawm daim ntawv thov no, nrog 0.3 hli muaj nyob rau ntawm qhov kev thov, thiab qhov kawg ntawm qhov ntau yuav qis dua - ua ntawm 125 kHz qhov twg qhov ntim flux loj dua. Huab cua sib txawv ib leeg yog qhov phem tshaj plaws ntawm ob lub ntiaj teb: nws ntxiv ntau ntev ua ntej nws ntxiv ntau yam.
Yog vim li cas qhov khoom xa tuaj ntawm no yog kev ntsuas es tsis yog kev thov. Daim duab centimeter tsis zoo taug kev ntawm cov haujlwm, vim hais tias nyob rau hauv ib qho kev sib txuas ua ke lub qab nthab tau teeb tsa los ntawm tus nyeem ntawv: txoj cai tseem ceeb ntawm tus ntiv tes xoo yog qhov siab tshaj plaws thaj av ntawm kwv yees li ib mus rau ob npaug ntawm tus nyeem ntawv kav hlau txais xov txoj kab uas hla. Qhov kev mus ncig yog qhov piv txwv. Cov lus hauv qab no yog lub hnab ntawv lees paub peb ua haujlwm rau ntawm cov ntawv nplaum tsim, qhia tawm tsam txhua pawg ntawm tus kheej liab qab-nto hauv qab:
| Mounting mob | Kev tsim kho | Cov txiaj ntsig xav tau vs lub hauv paus | Txiav txim |
|---|---|---|---|
| Pleev tsis yog- hlau nto | Standard 0.9 hli sticker | 100% los ntawm txhais. Ntawm 25-30 mm npib daim nplaum tiv thaiv tus nyeem ntawv phab ntsa no zaum ntawm qhov qis kawg ntawm cov ntawv luam tawm 1-10 cm band | Cov ntaub ntawv rau batch |
| Hlau phaj, tiv tauj ncaj qha | Standard 0.9 hli sticker | Zero, feem ntau tsis nyeem txhua | Tsis txhob hais qhov tsim no |
| Hlau phaj | Daim ntawv nplaum + 0.2–0.3 mm ferrite | 60–80% | Txais ntawm Ntau dua lossis sib npaug rau 60% |
| Xov tooj rov qab, tshaj lub roj teeb | Standard 0.9 hli sticker | Zero | Tsis txhob hais qhov tsim no |
| Xov tooj rov qab, ntug, ntshiab ntawm lub charger coil | Daim ntawv nplaum + 0.2–0.3 mm ferrite | 40-70%, sib txawv ntawm tes | Txais ntawm Ntau dua lossis sib npaug li 50% hla peb lub xov tooj qauv |
Khiav qhov no ib zaug tawm tsam koj tus kheej nyeem ntawv thiab sau tus qauv thiab kav hlau txais xov txoj kab uas hla ntawm tus lej. Ib daim ntawv no teb feem ntau ntawm cov neeg siv khoom yuav nug dab tsi hauv thawj lub hlis ntawm kev nthuav tawm. Thiab yog hais tias lub xov tooj -mount constraint hloov tawm tsis yog qhov tseem ceeb, lub keyfob vaj tse sidesteps tag nrho cov teeb meem, uas yog tsim nyog rau hnyav ua ntej cog rau ib daim ntawv nplaum rau tag nrho (fob xaiv rau kev nkag mus tswj tej yaam num).
Qhov twg Cloning raug cai nres
Muaj ib qho nyuaj rau pawg no, thiab ncaj qha txog nws yog ib feem ntawm kev ua tus neeg muag khoom ntseeg tau. Cov ntawv pov thawj encrypted xws li DESFire EV3, SEOS, thiab MIFARE tiam tam sim no tau tsim tshwj xeeb los tiv thaiv kev sib tw, thiab ntau tus neeg nyeem tam sim no tsis lees txais cov ntawv luam tawm tam sim no. Tsuas yog legacy, unencrypted formats yog xyaum duplicated. Kev lag luam dav yog txav mus rau txoj kev txhob txwm tshaj tawm: nkag mus- tswj cov neeg nyeem tau txav deb ntawm qhov tsawg- zaus, yooj yim theej cov ntawv sib thooj mus rau encrypted ntse daim ntawv pov thawj thiab ntau-factor authentication ntawm lub qhov rooj (360 iResearch). Ib daim ntawv nplaum RFID duplicate rau kev tswj xyuas muaj lub hauv paus chaw nyob, thiab ua piv txwv tsis muaj tus neeg yuav khoom nyiam.
"Compatible" kuj tsis yog lub ntsiab lus rau "suab". Thaum cov kws tshawb fawb tau tshuaj xyuas FM11RF08S, lub nti muag dav dav raws li MIFARE Classic- hloov pauv tau zoo, lawv pom cov khoom siv rov qab tuaj yeem ncav cuag los ntawm daim npav -tsuas yog tawm tsam, muaj peev xwm nthuav tawm tus neeg siv- cov yuam sij tau hais tseg (Quarkslab, ntawm CyberInsider).
Yog li cas tus neeg yuav khoom yuav tsum ua nrog qhov ntawd? Peb yam, txhua yam muaj tseeb los ntawm koj sab ntawm lub rooj. Nug tus naj npawb nti thiab tus neeg muag khoom tuag los ntawm lub npe es tsis yog tsev neeg, vim tias "MIFARE- tau tshaj 1K" piav qhia ntau lub chips nrog cov keeb kwm kev ruaj ntseg sib txawv. Nug seb tus neeg muag khoom puas tau txais nws cov chips los yog yuav cov khoom ua tiav, vim tias lub Hoobkas uas khiav nws tus kheej nti- cov kab sib txuas tau txais IC ntau ncaj qha thiab tuaj yeem qhia rau koj tias ib pawg tuaj ntawm qhov twg, thaum lub tsev lag luam rov muag inlays feem ntau ua tsis tau. Thiab nug yuav ua li cas tshwm sim thaum tus neeg muag khoom tuag raug cuam tshuam rau pej xeem ib nrab ntawm - daim ntawv cog lus: leej twg tsim nyog hloov, thiab raws li lub sijhawm teem tseg. Tus neeg muag khoom uas tau xav txog qhov ntawd yuav teb rau hauv kab lus. Ib tug uas tsis tau yuav hloov qhov kev kawm rau tus nqi. Tib lub laj thawj tswj hwm li cas daim ntawv pov thawj kev ruaj ntseg tau teev tseg hauv cov haujlwm tos txais qhua, qhov twgkev ruaj ntseg assumption qab tsev so key cardszoo li yuav raug tshuaj xyuas ntau dua li hauv kev ua haujlwm hauv tsev.
Kev Tso Cai, Tsis Muaj Peev Xwm
Seb puas yog daim ntawvraug caiyuav luag tsis muaj dab tsi ua nrog seb nws yogtechnically ua tau. Cov ntaub ntawv pov thawj nkag tau nquag raug kho raws li cov cuab yeej tswj hwm tsis yog cov khoom ntiag tug, thiab cov xwm txheej ntawd tshwm sim hauv cov tsev xauj tsev, cov cai lij choj hauv tsev, thiab HOA cov cai. Txoj kev txiav txim siab mus rau ib daim ntawv pov thawj ntxiv feem ntau yog lub tsev tsim cov txheej txheem tso tawm, qhov twg cov ntawv luam tshiab tau sau npe thiab qhov qub tuaj yeem raug tshem tawm thiab tshawb xyuas (Nimbio). Kev xaiv luam theej tus fob tseem ceeb rau lub clone RFID daim nplaum sab nraud uas cov txheej txheem daws qhov tsis yooj yim thiab tsim kom muaj qhov sib txawv ntawm tus account, vim tias kev tswj hwm yuav tsis paub txog cov ntawv pov thawj ntxiv.
Peb muab cov lag luam ua lag luam nyob rau hauv cov ntawv tso cai no: cov kws kho qhov muag, cov ntaub ntawv pov thawj - cov kev pabcuam duplicate, cov neeg ua haujlwm sib koom ua ke, thiab cov tswv cuab muab cov ntaub ntawv pov thawj rov qab rau lawv tus kheej cov neeg xauj tsev. Peb tsis muab ib yam dab tsi tsim los rhuav tshem kev ruaj ntseg, thiab hais meej meej tias yog ib qho tshwj xeeb tshaj li qhov tsis lees paub.
Nws kuj tshwm sim los piav txog peb cov neeg siv khoom zoo tshaj plaws. Cov neeg yuav khoom uas twb paub tias daim ntawv pov thawj twg lawv tau tso cai rov tsim dua, thiab leej twg tuaj yeem sau nws, yog cov uas nug cov lus nug hauv nqe lus tom ntej, vim tias lawv txoj kev pheej hmoo tsis raug cai. Nws yog batch uas tsis ua.
Yuav Ua Li Cas Tiag Tiag, thiab Yuav Ua Li Cas Thaum Cov Lus Teb Tsis Txaus
Feem ntau cov teeb meem nrhiav khoom hauv pawg no tiv thaiv tau ntawm kev yuav khoom - theem xaj. Rau qhov yuav tsum tau pinning cia tias cov npe nrov tawm hauv ntab, thiab ib qho loj OEM cloneable RFID daim ntawv nplaum yuav tsum teb tag nrho rau yam tsis muaj hedging: tus naj npawb ntawm cov nti thiab nws qhov chaw tuag; cov khawv koob tiam, hais qhia meej tias yog ib qho - sij hawm - sau rov sau dua; txoj kab uas hla thiabtag nrhothickness nrog rau tej txheej ferrite; nplaum qib thiab cov substrate nws yog ntsuas rau; cov khoom xeem tawm, lub ntsiab lus zaus, nyeem qhov deb thiab cov ntaub ntawv ncaj ncees, nrog rau tus nqi them; thiab ntau traceability.
Cov npe yog qhov yooj yim ib nrab. Ib nrab uas tiv thaiv ib qho cloneable RFID daim ntawv lo lag luam wholesale yog paub tias cov lus teb tsis muaj zog txhais tau li cas thiab yuav ua li cas txog nws.
Yog hais tias tus neeg muag khoom muab ib lub chiptsev neeges tsis txhob ntawm ib feem, uas feem ntau txhais tau tias lawv yuav tiav inlays thiab tsis tswj tus tuag. Ua haujlwm tau rau tsawg - qhov kev pheej hmoo tsawg, tab sis tsis txhob nug lawv cov lus nug uas lawv tsis tuaj yeem teb, thiab pob nyiaj siv rau koj tus kheej kev tshuaj xyuas tuaj. Yog tias lawv tsis tuaj yeem hais txog cov cim ua khawv koob, xav tias cov batch yog sib xyaw thiab tsis lees txais nws lossis tus nqi hauv kev txheeb xyuas cov kauj ruam. Yog tias qhov kev xeem dhau mus tau piav qhia tias yog "sampling" yam tsis muaj tus nqi, nug tus nqi thiab AQL; tus neeg muag khoom uas kuaj 100% yuav hais tam sim ntawd, vim nws raug nqi nyiaj thiab lawv xav tau credit rau nws. Yog tias lawv tsis tuaj yeem muab ntau tus lej, koj tsis muaj txoj hauv kev los cais cov pawg tsis zoo tom qab, uas yog ib qho kim tshaj plaws ntawm cov npe no kom pom tom qab qhov tseeb. Thiab yog hais tias lub thickness hais tsis suav nrog ferrite txheej, rov- ntsuas tus qauv koj tus kheej, vim hais tias qhov tsis sib xws yog dab tsi tig lub xov tooj -mount project rau hauv ib qho rov qab.
Ntawm peb sab cov lus nug no muaj cov lus teb tseem ceeb vim tias cov txheej txheem tau tswj hwm qhov kawg: tooj liab- xov hlau kav hlau txais xov winding tuav mus rau kwv yees li ± 0.1 hli, hauv - lub tsev chip bonding ntawm ib hnub muaj peev xwm ntau pua txhiab tus, thiab 100% kev tshuaj xyuas tawm ntau dua li cov qauv. Qhov ntawd ± 0.1 hli yog qhov zaus spec hauv kev zais. Coil geometry teeb tsa inductance, inductance teeb tsa qhov twg lub cim resonates, thiab lub ntsiab lus resonant uas wanders chav tsev mus rau chav tsev txhais tau tias qee daim hauv ib pawg zaum ze rau ntawm ntug ntawm tus nyeem ntawv lub qhov rais siab dua li lwm tus. Cov no yog cov ntawv nyeem tsis tu ncua ntawm lub qhov rooj thaum cov khoom xa tuaj, thiab lawv kuj yog vim li casvalidating ib qho piv txwv tawm tsam tus nyeem ntawv lub hom phiaj ua ntej cog lus rau ntimyog tsim nyog rau ob lub lis piam nws raug nqi. Yog tias koj qhov project xav tau ib daim ntawv, thickness, los yog ferrite tsim uas tsis yog nyob rau hauv tus txheej txheem catalogue, uas yog ib tugcov cuab yeej thiab cov lus nug txheej txheem peb ua hauv -tseves tsis yog ib qho kev tawm dag zog.
Ib Daim Ntawv Ceeb Toom Los Ntawm Ib Ntev -Khiav Account
Ib qho ntawm peb txoj kev sib raug zoo ntev tshaj plaws yog nrog lub tuam txhab Fab Kis nyob rau sab saum toj ntawm lub tsev - nkag mus - kev lag luam luam ntawv pov thawj. Tshaj li tsib xyoos lawv tau muab kwv yees li 500,000 daim fobs ib xyoos los ntawm peb, thiab qhov kev txiav txim siab uas ua rau nws ua haujlwm tsis yog nqi.
Lawv tau teev ib qho - sij hawm- sau FUID nti es tsis yog ib qho kev sau ntawv tsis muaj qhov kawg. Qhov laj thawj yog kev lag luam. Thaum ib daim ntawv pov thawj tawm ntawm lawv lub txee, lawv xav kom nws tsis tuaj yeem ua tsis tau rau cov neeg siv khoom kawg, lossis ib tus neeg qis qis, rov sau dua rau lwm yam thiab muaj qhov rov qab mus rau lawv lub npe. Peb kuj tau txiav cov cuab yeej tshiab kom lawv cov fobs nqa lawv tus kheej lub logo, uas tau kaw rau lwm ib nrab ntawm cov teeb meem tib yam: cov khw luam tawm dhau ntawm cov vaj tsev dav dav raws li lawv cov khoom. Tsib xyoos thiab kwv yees li 2.5 lab units tom qab ntawd, cov lus nug ntawm nti- tiam neeg tsis tau rov qab los ua qhov teeb meem kev txhawb nqa, vim nws tau teb ib zaug, sau ntawv, ua ntej thawj qhov kev txiav txim tau muab tso rau.
Qhov ntawd yog tag nrho cov lus sib cav rau kev kho tus clone RFID daim nplaum raws li qhov tshwj xeeb tsis yog khoom muag. Yog tias koj xav ua haujlwm los ntawm kev lag luam tib yam -offs rau koj tus kheej ntim, npog tiam chip, thickness, ferrite tsim thiab kev ntsuam xyuas, peb cov engineers yuav ua nws tawm tsam tus qauv tiag tiag thiabspec daim ntawv ua ntej koj cog lus rau tooling.
FAQ
Dab tsi nti siv rau hauv clone RFID daim nplaum?
Feem ntau 125 kHz cloneable stickers siv T5577 los yog EM4305, sau los ua raws li EM4100 / TK4100 ID hom ntawv. Lub 13.56 MHz versions siv MIFARE Classic-ntau tshaj nti nrog cov ntawv sau tau 0. Ob qhov tsis sib hloov, vim qhov zaus yuav tsum phim tus nyeem ntawv.
Vim li cas lub clone RFID daim nplaum tsis ua haujlwm ntawm lub xov tooj lossis hlau nto?
Hlau absorbs lub coil lub zog thiab detunes nws, txiav ntau yam sharply los yog thaiv nws tag nrho, thiab ib lub xov tooj NFC kav hlau txais xov, roj teeb thiab wireless - charging coil compound cov nyhuv. Cov ntawv nplaum rau cov chaw no xav tau txheej txheej ferrite cais tawm, thiab txoj haujlwm mounting tseem yuav tsum tau sim.
Txhua qhov kev nkag mus rau fob puas tuaj yeem luam rau ib daim ntawv nplaum?
Tsis yog. Cov ntaub ntawv pov thawj zoo li DESFire EV3 thiab SEOS yog tsim los tiv thaiv kev sib tw, thiab ntau tus neeg nyeem niaj hnub tsis lees txais cov ntawv luam. Tsuas yog legacy, unencrypted formats yog xyaum duplicate, thiab txawm tom qab ntawd tsuas yog nrog tus tswv system tso cai.
Tus neeg yuav khoom yuav tsum qhia dab tsi thaum xaj T5577 RFID daim nplaum nyob hauv ntau?
Chip tus naj npawb thiab qhov chaw tuag, cov cim khawv koob (ib - lub sijhawm- sau rov sau dua), txoj kab uas hla thiab tag nrho cov tuab, seb puas muaj txheej ferrite suav nrog, qib nplaum, cov khoom xeem dhau mus nrog tus nqi them, thiab ntau qhov kev taug qab.
