yuam kev 2: Xaiv qhov tsis ncaj ncees lawm nti rau cov ntaub ntawv payload
Peb niaj hnub pom cov neeg siv khoom xaj NTAG213 cim npe rau cov haujlwm uas yuav tsum tau khaws cov ntaub ntawv vCard tag nrho, tsuas yog pom tias 144 bytes tsis txaus rau lub npe, npe, tuam txhab, xov tooj, email, thiab lub vev xaib. Lub cim npe tsis tuaj yeem raug programmed lossis yuav tsum tau txiav cov chaw tseem ceeb.
Qhov kho:Xam koj cov ntaub ntawv xav tau ua ntej xaiv lub nti. URL luv luv xav tau 50-100 bytes (NTAG213 zoo). Ib daim vCard tiav xav tau 300–600 bytes (xaiv NTAG215 lossis NTAG216).
Qhov yuam kev 3: Tsis quav ntsej cov xov tooj cuam tshuam
Cov neeg siv feem ntau tshaj tawm tias NFC cim npe "tsis ua haujlwm" thaum qhov teeb meem tiag tiag yog cov ntaub ntawv xov tooj tuab, tshwj xeeb tshaj yog cov teeb meem nrog ua - hauv cov nplhaib hlau, sib nqus mounts, lossis MagSafe- cov ntawv txuas. Cov ntsiab lus hlau no nyob rau hauv rooj plaub cuam tshuam nrog NFC kav hlau txais xov, txo lossis tshem tawm kev muaj peev xwm nyeem.
Hauv peb cov kev paub dhau los txhawb cov neeg muag khoom muag nrog kais -kom- tshuaj xyuas cov teeb tsa, kwv yees li 8 ntawm 10 "tag tsis nyeem" cov lus tsis txaus siab tau daws lub sijhawm tus neeg siv khoom tshem tawm lawv lub xov tooj. Nug txog rooj plaub ua ntej, hloov lub cim thib ob.
Qhov yuam kev 4: Tshem cov cim npe xauv rau hauv qhov chaw pej xeem
Ib qho NFC tag uas tseem nyob hauv "sau" hom tuaj yeem sau tau dhau los ntawm txhua tus neeg uas muaj NFC- qhib lub xov tooj thiab tag dawb- sau ntawv app. Cov neeg ua phem phem tau paub los hloov NFC tag cov ntaub ntawv raug cai hauv cov chaw pej xeem, hloov cov kais dej mus rau phishing cov vev xaib lossis nplooj ntawv rub tawm malware tsis yog cov phiaj xwm phiaj xwm.
Kev xyaum zoo tshaj: Ib txwm kaw koj cov cim NFC kom nyeem -tsuas yog hom tom qab programming. NTAG21x chips txhawb tus password- tiv thaiv kev xauv, thiab kev xauv lub cim mus tas li tiv thaiv kev hloov pauv yav tom ntej. Rau cov pej xeem - ntsib kev xa tawm, kev tshuaj xyuas lub cev ib ntus ntawm koj cov cim npe kuj raug pom zoo.
NFC Tag Kev Ruaj Ntseg: Yam Koj Yuav Tsum Paub

- Cov kws tshaj lij lossis cov neeg siv khoom-fab → PVC phaib lossis acrylic sawv
- Hlau nto → Anti- hlau tag nrog ferrite shielding
- Hnyav ib puag ncig → Epoxy-encapsulated lossis silicone-cov ntawv kaw
- Wearable siv → Silicone wristbands lossis keyfobs
Kauj Ruam 4: Thov cov qauv thiab kuaj ua ntej cog lus.Ntsuam xyuas koj cov cim npe nrog cov xov tooj tiag tiag, nyeem ntawv, thiab qhov chaw koj yuav siv hauv kev xa tawm. Ib kauj ruam no yuav zam tsis dhau qhov kev xa tawm ntau tshaj plaws: cov teeb meem kev sib raug zoo ntawm qhov chaw, nyeem - ntau yam surprises, thiab cov teeb meem adhesion uas tsuas tshwm sim hauv cov xwm txheej tiag tiag.
FAQ
Q: NFC tag txhais li cas?
A: Ib qho NFC (Nyob ze Kev Sib Txuas Lus) tag yog ib qho me me, roj teeb - khoom siv dawb uas muaj cov nti thiab kav hlau txais xov. Nws wirelessly xa cov ntaub ntawv khaws cia rau NFC- pab kiag li lawm xws li smartphones thaum lawv tuav hauv ob peb centimeters. NFC cov cim npe ua haujlwm ntawm 13.56 MHz thiab tswj hwm los ntawm cov qauv thoob ntiaj teb suav nrog ISO / IEC 14443. Yog tias koj tau pom "NFC tag kuaj pom" ceeb toom hauv koj lub xov tooj, nws txhais tau tias koj lub cuab yeej lees paub lub cim nyob ze thiab npaj los nyeem nws cov ntaub ntawv.
Q: NFC cim npe ua haujlwm li cas yam tsis muaj roj teeb?
A: NFC cim npe siv electromagnetic induction. Thaum lub cuab yeej nyeem ntawv (xws li lub xov tooj smartphone) los ze, nws lub tshuab hluav taws xob hluav taws xob muab lub zog txaus rau lub zog rau lub cim npe nti, uas tom qab ntawd xa nws cov ntaub ntawv rov qab mus rau tus nyeem ntawv.
Q: Dab tsi yog qhov txawv ntawm NFC cov cim npe thiab QR cov lej?
A: NFC cim npe sib txuas lus los ntawm xov tooj cua nthwv dej nrog tus kais, thaum QR cov lej raug kuaj pom pom nrog lub koob yees duab. NFC cim npe yog rov sau dua, muaj kev nyab xeeb dua (txhawb kev encryption thiab lo lus zais xauv), thiab muab kev paub siv ceev dua. QR cov lej yog pheej yig dua los tsim tab sis tsis muaj kev ruaj ntseg thiab tsis tuaj yeem hloov kho thaum luam tawm.
Q: NFC cov cim npe puas tuaj yeem ua haujlwm ntawm cov hlau nplaum?
A: Standard NFC cov cim npe ua tsis tiav ntawm cov hlau vim muaj kev cuam tshuam electromagnetic. Anti-hlau NFC cov cim npe, uas suav nrog ferrite shielding txheej, tshwj xeeb tsim los ua haujlwm ruaj khov ntawm cov hlau nplaum thiab tau siv dav hauv kev lag luam, IT, thiab kev siv logistics.
Q: Kuv yuav xaiv txoj cai NFC tag nti li cas?
A: Ua ke lub nti rau koj cov ntaub ntawv xav tau. NTAG213 (144 bytes) ua haujlwm rau luv URLs thiab yog tus pheej yig tshaj plaws. NTAG215 (504 bytes) suits digital business cards and medium data loads. NTAG 216 (888 bytes) tuav cov ntaub ntawv loj tshaj plaws. Tag nrho peb yog universally sib xws nrog NFC smartphones.
