Hauv ntiaj teb ntawm kev txheeb xyuas wireless,NFC (Nyob ze rau kev sib txuas lus)yog technically thiab xyaumnyab xeeb duatshaj tus qauvRFID.
Thaum NFC yog qhov tshwj xeeb tshwj xeeb ntawm RFID thev naus laus zis, lawv ua haujlwm sib txawv hauv txoj hauv kev uas cuam tshuam ncaj qha rau koj txoj kev nyab xeeb. Nov yog qhov kev tawg ntawm vim li cas NFC tuav qhov kom zoo dua:
1. Kev sib txuas lus ntau yam (Qhov "Kev Tiv Thaiv" sib thooj)
RFID (UHF):Ntev -ntau RFID tuaj yeem nyeem los ntawmob peb metersnyob deb. Tus nyeem ntawv siab - lub zog muaj peev xwm theoretically "sniff" ib daim ntawv cim RFID passive (xws li cov siv hauv cov tsev khaws khoom lossis ntawm lub tshuab cua) los ntawm thoob plaws ib chav yam tsis muaj koj paub.
NFC:NFC raug txwv rau qhov luv luv, feem ntautsawg dua 4cm (li 1.5 nti). Qhov kev xav tau "kev sib thooj ntawm lub cev" ua raws li kev nyab xeeb kev nyab xeeb; ib tug hacker yuav tsum tau xyaum kov koj lub hnab tshos los yog lub hnab mus sim scan.
2. Encryption thiab Dynamic Data
Txheem RFID:Feem ntau cov cim RFID yooj yim (xws li cov phuam so hauv tsev so lossis warehouse pallets) yog " ruam." Lawv tsuas yog tshaj tawm tus lej ID zoo li qub rau txhua tus uas pings lawv. Yog tias ib tug neeg clones tus ID, lawv tuaj yeem ua tus cim.
NFC:NFC chips, tshwj xeeb tshaj yog cov siv hauv credit cards thiab mobile wallets (Apple/Google Pay), kev txhawb nqacomplex encryption. Es tsis txhob xa koj daim npav tiag tiag, lawv tsim aib -time token. Txawm hais tias ib tug neeg cuam tshuam cov teeb liab, cov ntaub ntawv tsis muaj txiaj ntsig rau kev hloov pauv thib ob.
3. Ob-Txoj Kev Sib Txuas Lus (Qhov "Smart" Factor)
RFID:Feem ntau aib -txoj kevtxoj kev. Lub cim nyob ntawd, thiab tus nyeem ntawv rub cov ntaub ntawv los ntawm nws.
NFC:Muaj peev xwm ntawmob-txoj kev (peer-rau-peer)kev sib txuas lus. Qhov no tso cai rau "ua haujlwm" kev ntsuas kev nyab xeeb, xws li lub xov tooj xav tau kev kuaj xyuas biometric (FaceID lossis ntiv tes) ua ntej nws pom zoo xa cov ntaub ntawv mus rau qhov chaw them nyiaj.
Lub rooj sib piv
| Feature | Txheem RFID | NFC |
| Hom kab mob | Txog li 10+ meters | Tsawg dua 4 cm |
| Qib kev ruaj ntseg | Tsawg (Cov ntaub ntawv zoo li qub) | Siab (Encrypted / Dynamic) |
| Kev siv thawj zaug | Supply chain, Tolls, Asset tracking | Kev Them Nyiaj, Cov Ntsiab Lus Digital, Cov Ntaub Ntawv Sib Pauv |
| Risk ntawm Skimming | Siab dua (vim ntau yam) | Tsawg heev |
Summary of Risks
RFID yog tsim rau efficiency:Nws yog tsim los taug qab 500 yam khoom hauv lub tsheb thauj khoom ib zaug. Nws "tsis muaj zog" yog tias nws yooj yim dhau los hnov los ntawm qhov deb.
NFC yog tsim rau kev lag luam:Nws yog tsim los rau kev ruaj ntseg, txhob txwm sib cuam tshuam ntawm ob qho khoom siv tshwj xeeb.
Qhov Kev Txiav Txim:Yog tias koj txhawj xeeb txog "digital pickpocketing,"NFC muaj kev nyab xeeb ntau dua.Yog tias koj muaj - zaus RFID phaib (xws li daim npav qub chaw ua haujlwm), lawv yog cov uas yuav tau txais txiaj ntsig los ntawm RFID- lub tes tsho thaiv, qhov uas koj lub xov tooj NFC twb tau tiv thaiv zoo heev los ntawm lub kaw lus software.
