NFC Tag Kev Tiv Thaiv Tus Kheej Vs Kev Xauv Mus Ib Txhis: Yuav Ua Li Cas Xaiv Ua ntej xa tawm
Sep 24, 2026
Tso lus
Thaum NFC tag siv rau hauv pej xeem lossis cov neeg siv khoom- ntsib kev xa tawm, cov ntsiab lus yuav tsum tsis txhob hloov kho los ntawm kev sib tsoo. Tab sis "lock the tag" tuaj yeem txhais tau ntau yam sib txawv, thiab xaiv qhov tsis ncaj ncees lawm tuaj yeem tsim teeb meem uas tsis tuaj yeem kho tom qab tsim khoom.
Qhov kev txiav txim siab zoo yog tias daim ntawv yuav tsum nyob twj ywm sau tau, xav tau tus password rau kev tiv thaiv kev ua haujlwm nco, lossis nyeem tas mus li - nkaus xwb. Ib lo lus nug thib plaub zaum sab nraum qhov kev xaiv: yog tias qhov project xav tau los ua pov thawj tias lub cev tag yog qhov tseeb, kev tiv thaiv tus password yooj yim lossis nyeem - tsuas yog xauv tsis txaus.
Cov lus qhia no yog rau cov pab pawg B2B npaj NFC cov ntawv nplaum, cov ntawv lo, daim npav, cov lus qhia lossis lwm lub xov tooj - nyeem tau cov cim rau kev xa tawm ntau. Nws tsom mus rau kev txiav txim siab xa mus, kev tsim ua ntu zus thiab cov qauv kev lees paub es tsis yog app - cov txheej txheem tshwj xeeb.
Plaub Yam Yuav Tsum Tau Muaj Feem ntau hu ua "Security"
| Kev xav tau | Qhov nws yeej tswj tau | Hom kev siv | Kev txwv loj |
|---|---|---|---|
| Sau tag | Cov ntsiab lus tseem tuaj yeem hloov pauv | Pilots, commissioning, internal workflows | Ib tug neeg uas tsim nyog sau ntawv tuaj yeem hloov cov ntsiab lus |
| Lo lus zais - tiv thaiv lub cim xeeb | Xaiv lub cim xeeb ua haujlwm yuav tsum muaj kev lees paub los ntawm lub nti | Kev hloov kho tshiab uas yuav xav tau kev hloov pauv yav tom ntej | Kev tiv thaiv tus password tsis zoo ib yam li encryption lossis pov thawj ntawm qhov tseeb |
| Kev nyeem tas mus li -tsuas yog xauv | Xaiv cov nplooj ntawv nco tsis tuaj yeem rov sau dua | Pej xeem tag nrog kawg, pom zoo payloads | Irreversible tom qab qhov cuam tshuam cov khoom xauv raug teeb tsa |
| Cryptographic authentication | Backend lossis tus nyeem ntawv txheeb xyuas cov lus teb cryptographic | Kev tiv thaiv-kev ua cuav thiab siab dua- daim ntawv thov kev nyab xeeb | Yuav tsum muaj peev xwm sib txawv chip thiab system architecture |
Cov no tsis hloov pauv tau. Ib qho URL kaw mus tas li tseem tuaj yeem luam tawm thiab rov ua dua ntawm lwm daim ntawv cim npe. Ib lo lus zais tuaj yeem txwv qee qhov kev ua haujlwm nco tsis tau encrypting pej xeem NDEF URL. Ib txoj haujlwm pov thawj ruaj ntseg tseem tuaj yeem siv NDEF URL, tab sis tus nqi kev nyab xeeb yog los ntawm cov txheej txheem cryptographic thiab cov ntaub ntawv pov thawj rov qab, tsis yog los ntawm qhov tseeb tias daim ntawv nyeem yog - nkaus xwb.
Yog tias koj xav tau qhov dav NFC cov hauv paus ua ntej, Syntek'sNFC tag cov lus qhiayog tus tswv uas pib ua haujlwm. Nplooj ntawv no pib ntawm qhov chaw uas cov ntsiab lus tag thiab xa mus ua haujlwm twb muaj lawm.
Yuav Ua Li Cas Kev Xauv Xauv txhais tau tias ntawm NTAG21x Tags
NXP piav qhia NTAG213, NTAG215 thiab NTAG216 as NFC Forum Type 2 Tag raws ICs nrog ob qho tib siteb-programmable nyeem-tsuas yog xauv muaj nuj nqithiabconfigurable 32-ntsis lo lus zais tiv thaiv. Cov no yog cais mechanisms.
HauvNTAG 213/215/216 data sheet, lub static lock bytes thiab dynamic lock bytes tswj seb tus neeg siv txhais tau li cas -cov nplooj ntawv nco tuaj yeem sau dua. Thaum lub xauv me ntsis cuam tshuam tau teeb tsa, thaj chaw tiv thaiv tau nyeem - nkaus xwb. Kev ntsuas phoo - txheej txheem me ntsis yog ib qho - txoj kev: ib qho programmed xauv me ntsis tsis tuaj yeem hloov pauv rov qab los ntawm 1 mus rau 0.
Tias yog vim li cas kev kaw ruaj khov nyob rau qhov kawg ntawm txoj kev pom zoo, tsis yog thaum pib ntawm kev encoding.
CovChrome Web NFC cov ntaub ntawvsiv tib lub tswv yim ua haujlwm rau cov ntawv txhawb nqa: ua ib daim ntawv nyeem -tsuas yog kev ua haujlwm ruaj khov, ib qho - txoj kev ua haujlwm thiab tsis tuaj yeem thim rov qab los ntawm kev ua haujlwm NDEF ib txwm.
Kev tiv thaiv tus password yog thim rov qab tswj, tsis yog encryption
NTAG21x kuj tseem muaj kev tiv thaiv tus password. NXP sau ib lo lus zais -kev lees paub kev lees paub, kev tiv thaiv- thaj chaw pib thiab nkag mus rau qhov chaw uas tuaj yeem txwv kev sau ntawv lossis, nyob ntawm kev teeb tsa, nyeem thiab sau cov haujlwm.
Qhov ntawd ua rau tus password-raws li kev tswj hwm muaj txiaj ntsig thaum tus neeg siv tau tso cai yuav tsum tau hloov kho cov ntsiab lus tiv thaiv tom qab.
Txawm li cas los xij, 32-ntsis tag lo lus zais yuav tsum tsis txhob ua lag luam raws li encryption lossis siab -kev ruaj ntseg authentication. Nws yog ib qho kev nkag tau -tswj feature rau kev ua haujlwm nco. Yog tias ib lub cim muaj qhov URL pej xeem uas txhua tus yuav tsum tau nyeem, kev tiv thaiv tus password tsis ua rau qhov URL tsis pub lwm tus paub.
Nws kuj tseem tsim kom muaj kev vam khom rau kev ua haujlwm: qee tus neeg yuav tsum muaj tus password, cov txheej txheem tsim tawm, txoj cai rov qab thiab cov cuab yeej siv los txheeb xyuas thiab hloov kho lub cim npe. Poob qhov kev tswj hwm tuaj yeem tig qhov kev xav rov sau dua tshiab rau hauv qhov kev coj ua uas tsis tuaj yeem tswj tau.
Siv Lub Sijhawm Kev Xa Mus Los Xaiv Lub Tswv Yim Xauv
| Deployment condition | Cov lus pom zoo | Yog vim li cas |
|---|---|---|
| Tus qauv lossis cov ntsiab lus tsav tsheb tseem hloov pauv | Khaws sau tau | Kev kaw ntxov ntxov qeeb qeeb iteration thiab tuaj yeem pov tseg cov qauv |
| Cov neeg ua haujlwm sab hauv yuav xav tau hloov kho cov cim xeeb tom qab | Xav txog tus password- tiv thaiv sau yog tias xaiv nti thiab kev ua haujlwm txhawb nqa nws | Khaws tswj kev kho kom raug |
| Public tag muaj qhov kawg ruaj khov URL | Xav txog kev nyeem tas mus li - tsuas yog xauv tom qab siv tau | Tiv thaiv kom tsis txhob rov sau dua qub ntawm qhov pom zoo payload |
| Cov ntsiab lus pej xeem hloov pauv tab sis URL tuaj yeem nyob ruaj khov | Xauv qhov URL ruaj khov thiab hloov kho lub vev xaib qhov chaw | Khaws lub cev tag ruaj thaum cov ntsiab lus hloov server-sab |
| Tag yuav tsum ua pov thawj qhov khoom lub cev yog qhov tseeb | Siv qhov kev lees paub- muaj peev xwm architecture | Nyeem-tsuas yog qhov xauv tsis tiv thaiv kev luam ntawm cov ntsiab lus zoo li qub |
Kev tswj hwm kev xa tawm pej xeem feem ntau yog qhov ruaj khov, lub tuam txhab - tswj URL sau rau lub cim npe, ua raws li cov neeg rau zaub mov - cov ntsiab lus hloov pauv. Hauv cov qauv ntawd, NFC lub cim xeeb tuaj yeem nyeem tau - tsuas yog thaum nplooj ntawv tsaws, cov ntsiab lus kev sib tw, cov ntaub ntawv pov thawj lossis cov ntaub ntawv khoom tseem tuaj yeem kho tau hauv online.
Syntek covlub website NFC tag qhianpog cov lus nug cais ntawm URL-raws li NFC xa tawm. Qhov kev txiav txim xauv ntawm no pib tom qab lub hom phiaj architecture tau pom zoo.
Tsis txhob kaw ib tus neeg muag khoom tas mus li -Tswj qhov chaw uas tsis muaj phiaj xwm tsiv teb tsaws chaw
Lub xauv ruaj khov khov rau qhov uas khaws cia ntawm lub nti, tsis yog qhov tshwm sim hauv internet. Qhov kev sib txawv ntawd muaj txiaj ntsig tsuas yog tias lub koom haum tswj hwm qhov chaw lossis muaj txoj kev tsiv teb tsaws chaw uas ntseeg tau.
Ua ntej xauv ib lub cim rau qhov URL, paub meej tias:
- leej twg yog tus tswv;
- leej twg tswj redirects;
- seb lub hom phiaj puas tuaj yeem txav mus rau lwm lub platform tom qab;
- seb qhov URL puas muaj tus neeg muag khoom- txoj kev tshwj xeeb uas yuav ploj mus;
- seb puas yog ib -tag cim tokens yuav tsum nyob twj ywm siv tau rau lub neej kev xa mus;
- Yuav ua li cas thaum lub phiaj xwm, cov neeg ua haujlwm, cov ntaub ntawv cov khoom lossis qhov chaw so haujlwm.
Ib daim ntawv tas mus li taw qhia rau SaaS URL pov tseg tuaj yeem dhau los ua kev ceeb toom lub cev mus tas li ntawm kev txiav txim siab software ib ntus. Rau ntev - nyob tag, kev tswj ntawm URL yuav tsum raug kho raws li ib feem ntawm cov khoom specification.
Xauv yuav tsum ua raws li kev nkag mus thiab ua haujlwm pom zoo
Kev nyab xeeb ntau lawm ib ntus caissau ntawv, pov thawjthiabxauv.
- Txuag txoj cai payload.Txhais hom ntaub ntawv NDEF tiag tiag, tus qauv URL, cim - txoj cai token thiab cov ntaub ntawv sib txawv.
- Encode tag.Sau qhov kev pom zoo payload siv cov txheej txheem tsim khoom.
- Nyeem nws rov qab hauv tshuab hluav taws xob.Xyuas kom tseeb tias cov ntaub ntawv khaws tseg yog cov ntaub ntawv hauv qhov chaw.
- Ntsuam xyuas cov neeg siv cov txiaj ntsig.Coj mus rhaub cov ntawv tiav nrog cov neeg sawv cev lub hom phiaj xov tooj lossis cov neeg nyeem thiab paub meej tias qhov kev npaj ua tiav.
- Txheeb xyuas qhov chaw.Txheeb xyuas cov kev hloov pauv, HTTPS tus cwj pwm, tus tswv ntawm tus account thiab ib qho kev qhia tshwj xeeb.
- Pom zoo ib qho kev tsim tawm - qauv sib npaug.Cov qauv yuav tsum siv cov nti kawg, inlay, cov khoom siv, qhov chaw nyob thiab kev cai encoding.
- Siv lub xeev tiv thaiv pom zoo.Tawm sau tau, teeb tsa tus password tswj, lossis kaw mus tas li raws li qhov project specification.
- Txheeb xyuas tus ncej-lock state.Nyeem cov ntsiab lus dua thiab paub meej tias qhov txwv kev sau ntawv xav tau yog qhov tseeb.
- Sau qhov tshwm sim.Khaws daim duab qhia chaw, qauv kho dua tshiab thiab ntsuas phoo - lub xeev xav tau nrog cov ntaub ntawv tsim khoom.
Qhov kev txiav txim no tiv thaiv qhov ua tsis tau zoo: nrhiav pom qhov tsis raug URL, luam theej duab lossis tsis raug NDEF cov ntaub ntawv tsuas yog tom qab lub cim tau ua tas mus li nyeem- nkaus xwb.
Rau Cov URLs tshwj xeeb, Daim Ntawv Qhia Cov Ntaub Ntawv Tseem Ceeb npaum li lub Xeev Xauv
Ib pawg ntawm NFC cov cim npe yuav muaj qhov URL sib xws, lossis txhua daim yuav nqa ib qho token sib txawv. Cov cim encoding ntxiv lwm hom tsis ua haujlwm: NFC tag tuaj yeem raug kaw kom raug tab sis tau kos npe rau cov khoom tsis raug.
Rau ib -txoj kev encoding, cov ntaub ntawv tsim khoom yuav xav tau cov teb xws li:
| Teb | Lub hom phiaj |
|---|---|
| Daim kab ke | Kev tsim khoom thiab ntim khoom siv |
| Printed serial lossis QR tus nqi | Tib neeg-pom lossis lub koob yees duab- nyeem tau siv tau |
| NFC UID | Electronic tag identifier qhov twg xav tau los ntawm qhov project |
| Encoded URL lossis token | NDEF qhov chaw tiag tiag |
| Kev tiv thaiv lub xeev | Sau tau, lo lus zais - tswj los yog nyeem tas mus li - nkaus xwb |
| Kev txheeb xyuas qhov xwm txheej | Hla, rov ua dua, cais tawm lossis lwm yam kev tswj hwm |
Xauv tsis kho daim ntawv qhia tsis zoo. Qhov tseeb ib ntus yog txhawm rau txheeb xyuas daim ntawv qhia ua ntej, tom qab ntawd siv lub xeev irreversible.
Yuav Ua Li Cas Tom Qab Tag Nrho Nyeem tas mus li -Tsuas
Qhov kev tshuaj xyuas zaum kawg yuav tsum ua pov thawj ob qho tib si tias cov ntsiab lus tseem ua haujlwm thiab muaj lub xeev kev tiv thaiv pom zoo.
| Kev lees txais | Qhov nws ua pov thawj |
|---|---|
| NDEF nyeem ntawv | Cov ntaub ntawv khaws cia tseem zoo li qhov pom zoo payload |
| Xov tooj los yog nyeem ntawv ua | Lub hom phiaj ntaus ntawv ua tiav cov neeg siv kev npaj ua haujlwm |
| Qhov chaw kuaj mob | Qhov URL daws teeb meem rau nplooj ntawv pom zoo lossis cov txiaj ntsig rov qab |
| Tshwj xeeb- data maping | Lub cev lub cev daws tau cov ntaub ntawv raug |
| Sau- txwv kev kuaj | Lub xeev kev tiv thaiv tshaj tawm tau ua haujlwm |
| Nto xeem | Daim ntawv tseem nyeem nyob rau hauv lub tiav mounting mob |
| QR rov qab xyuas | Ib qho kev luam tawm rov qab mus txog qhov chaw xav tau |
Rau kev txiav txim loj, txhais seb puas yog txhua yam khoom encoded lossis tus qauv tswj tau raug kuaj xyuas ntawm txhua txheej. Cov qauv qauv ntawd yog daim ntawv cog lus tus neeg yuav khoom / chaw tsim khoom; nws yuav tsum tsis txhob hloov los ntawm cov lus tsis meej uas cov cim npe "kuaj."
Kev kaw ruaj ruaj tsis daws lub cev tampering
Ib qho kev nyeem - tsuas yog NFC tag tsis tuaj yeem sau rov qab los ntawm kev ua haujlwm nco ib txwm, tab sis daim ntawv pej xeem tseem tuaj yeem raug tshem tawm, npog, hloov pauv lossis puas lub cev.
Rau kev teeb tsa pej xeem, xav txog seb qhov project puas xav tau:
- tamper- pov thawj kev tsim kho;
- periodic tshuaj xyuas lub cev;
- ib tug luam QR poob rov qab;
- ib tug tswj cov cuab tam / chaw sau npe;
- backend saib xyuas rau qhov chaw npaj txhij txog lossis siv token;
- kev hloov pauv rau cov cim npe puas lossis ploj lawm.
Lub cev kev ruaj ntseg yuav tsum tau nyob ntawm ib puag ncig. Daim ntawv tshuaj xyuas countertop, daim ntawv pov thawj cov khoom vaj khoom tsev sab nraum zoov thiab cov khoom lag luam - pov thawj pov thawj tsis muaj cov qauv kev hem thawj.
Kev tiv thaiv tus password tsis yog qhov hloov pauv rau kev lees paub
Qhov kev sib txawv no tseem ceeb tshaj plaws hauv kev tiv thaiv -cov haujlwm cuav.
Tus qauv cim tuaj yeem raug kaw mus tas li yog li nws lub cim xeeb tsis tuaj yeem hloov kho, tsis tau pom lossis nyeem tau cov ntaub ntawv tseem tuaj yeem muab theej rau lwm daim ntawv. Ib qho kev ruaj ntseg UID tuaj yeem pab tau raws li tus lej cim, tab sis kev cia siab rau tus cim ib leeg tsis zoo ib yam li cov ntaub ntawv pov thawj cryptographic.
Yog tias qhov kev xav tau ntawm kev lag luam yog "tiv thaiv kev sau ntawv tsis raug tso cai," kev kaw lossis lo lus zais - tswj kev sau ntawv raws li qhov tsim nyog. Yog tias qhov yuav tsum tau ua yog "ua pov thawj cov khoom siv lub cev no yog qhov tseeb," qhov project yuav tsum ntsuas lub nti thiab backend tsim los rau kev lees paub.
Qhov kev ruaj ntseg architecture yog txhob txwm tawm ntawm kab lus no. Tsis txhob tig tus nqi qis - tus nqi rau pej xeem URL tag rau hauv cov khoom "tiv thaiv- cuav" tsuas yog los ntawm kev hloov nws lub xeev xauv.
Txhais Lub Xeev Xauv hauv RFQ, Tsis Yog Tom Qab Ntau Lawm
| RFQ / pom zoo teb | Yuav qhia li cas |
|---|---|
| Chip / tag technology | Kev pom zoo IC lossis thev naus laus zis uas qhov kev tiv thaiv tus cwj pwm tseem ceeb |
| NDEF payload | URL, ntawv nyeem, cim token lossis lwm cov ntaub ntawv pom zoo |
| Cov ntaub ntawv qhov chaw | Cov ntaub ntawv ib txwm los yog rau ib -cov ntaub ntawv thiab kho dua tshiab |
| Kev tiv thaiv | Sau tau, lo lus zais - tswj los yog nyeem tas mus li - nkaus xwb |
| Tus tswv ntawm tus password | Leej twg tsim, khw muag khoom thiab tswj nws yog tias siv kev tiv thaiv tus password |
| Xauv lub sijhawm | Tom qab qhov kev txheeb xyuas qhov rooj xauv qhov rooj yuav tshwm sim |
| Daim phiaj xav tau | Kev sib raug zoo ntawm UID, luam tawm serial, QR thiab encoded token yog muaj |
| Kev lees txais | Readback, lo lus uas peb, ntaus ntawv, nto thiab sau ntawv - txwv kev kuaj |
| Exception tuav | Rework, hloov lossis cais tawm txoj cai rau cov khoom ua tsis tiav |
| Hloov tswj | Qhov twg nti, encoding, URL lossis tiv thaiv kev hloov pauv yuav tsum tau pom zoo dua |
Rau kev nrhiav ncaj qha ntawm xov tooj - nyeem tau NFC cim npe thiab cov ntawv cim, Syntek'sNFC tag qebyog tus tswv lag luam. Yog hais tias qhov project yuav tsum tau nyob rau hauv -tsev encoding thiab pov thawj, qhovNFC nyeem ntawv thiab sau ntawv qebyog txoj kev kho vajtse cuam tshuam.
Reorders Xav tau lub xauv -Lub Xeev Hloov- Tswj Txoj Cai
Ib daim ntawv xaj rov qab yuav tsum tsis txhob tau txais lo lus "zoo ib yam" yam tsis tau txhais tias yuav tsum nyob li cas.
Revalidation yuav tsum tau txiav txim siab thaum qhov kev hloov pauv cuam tshuam:
- nti qauv lossis kev nco / kev tiv thaiv tus cwj pwm;
- NDEF cov ntaub ntawv hom lossis URL qauv;
- kev sib piv nrog cov cim encoding;
- password configuration los yog kev tiv thaiv Scope;
- txoj cai kaw ruaj ruaj;
- luam serial lossis QR daim ntawv qhia;
- inlay, kav hlau txais xov lossis cov khoom tiav;
- mounting nto los yog npaj xov tooj / nyeem ntawv teeb.
Kev hloov kho kom zoo nkauj kos duab yuav tsis xav tau kev sim ua tiav, tab sis qhov kev hloov pauv uas tuaj yeem hloov RF tus cwj pwm, kev txhais cov ntaub ntawv, daim ntawv qhia lossis sau kev tiv thaiv yuav tsum ua rau kev tshuaj xyuas cov txheej txheem cuam tshuam.
Txoj Cai Txiav Txim
Xaiv lub xeev kev tiv thaiv los ntawm tus qauv tu, tsis yog los ntawm lo lus "kev ruaj ntseg."
Khaws tag sau tauthaum lub sij hawm xa tawm tseem tab tom ua haujlwm.Siv tus password- tswj kev nkagthaum tso cai rau yav tom ntej nco hloov tshiab yog qhov yuav tsum tau ua haujlwm tiag tiag thiab cov nti xaiv tau txhawb nqa tus cwj pwm xav tau.Siv cov ntawv nyeem tas mus li -tsuas yog xauvthaum lub encoded payload yog kawg thiab yuav tsum tsis txhob rov sau dua.Siv cryptographic authenticationthaum lub lag luam yuav tsum txheeb xyuas qhov tseeb es tsis yog tsuas yog tiv thaiv kev hloov kho tib yam nkaus xwb.
Rau kev tsim khoom ntau, qhov kev nyab xeeb tshaj plaws yog:
Txhais kev them nyiaj → encode → nyeem rov qab → xeem lo lus uas peb → txheeb xyuas daim ntawv qhia → pom zoo cov qauv tiav → thov kev tiv thaiv → txheeb xyuas kev tiv thaiv → tso tawm batch
Qhov kev ua ntu zus ua rau qhov ntsuas tsis tau rov qab los ntawm kev ua yuam kev ntau lawm.
