RFID blocking yog dab tsi?

Xov tooj cua Frequency Identification (RFID) thev naus laus zis siv lub zog los ntawm lub tshuab hluav taws xob los ua lub zog rau lub nti me me uas xa tawm cov lus teb. Piv txwv li, RFID nti hauv daim npav rho nyiaj muaj cov ntaub ntawv xav tau los tso cai rau kev ua lag luam, thiab RFID nti hauv daim npav nkag muaj cov lej qhib lub qhov rooj lossis lub kaw lus txwv.

Qee cov ntaub ntawv, tshwj xeeb tshaj yog cov hlau conductive, tiv thaiv electromagnetic tsis dhau los ntawm lawv. Tus tuav daim npav (lossis qee zaum tag nrho lub hnab nyiaj) ntawm RFID thaiv lub hnab nyiaj yog ua los ntawm cov khoom siv uas tsis pub xov tooj cua tsis dhau.

Ua li ntawd, lub nti tsis khau raj, thiab txawm tias nws ua, nws lub teeb liab tsis mus rau hauv lub hnab nyiaj. Cov kab hauv qab yog tias koj tsis tuaj yeem nyeem RFID daim npav los ntawm koj lub hnab nyiaj.


Vim li cas thiaj yuav tsum tau koj daim npav thaiv?

RFID cov cim npe yog cov khoom siv passive uas yuav zoo siab xa lawv cov ntaub ntawv rau txhua tus neeg uas yuav mloog. Nws yuav zoo li ib daim ntawv qhia rau kev ruaj ntseg tsis zoo, tab sis RFID cim npe uas tuaj yeem luam tawm ntawm qhov deb feem ntau tsis thauj khoom nrog cov ntaub ntawv rhiab heev. Piv txwv li, lawv siv los taug qab cov khoom muag lossis pob khoom. Nws tsis muaj teeb meem leej twg nyeem cov lus vim nws tsis yog qhov zais cia.

Kev txhawj xeeb txog daim npav RFID tau nce zuj zus raws li ntau thiab ntau NFC nyeem cov cuab yeej nrhiav lawv txoj hauv kev rau hauv tes ntawm cov pej xeem. NFC (Nyob ze Kev Sib Txuas Lus) yog ib qho cuab yeej zoo ib yam li RFID, qhov sib txawv tseem ceeb yog ntau yam. NFC chips tsuas tuaj yeem nyeem ntau yam hauv ntiv tes. NFC yog qhov tseem ceeb tshwj xeeb ntawm RFID.

Qhov no yog li cas "swipe to pay" cards ua hauj lwm nrog them nyiaj terminals nruab nrog NFC nyeem. Yog tias koj lub smartphone muaj peev xwm ntawm kev them nyiaj tsis sib cuag, nws kuj tuaj yeem siv los nyeem NFC phaib. Yog li yuav ua li cas koj txwv tsis pub ib tug neeg siv lawv lub xov tooj los luam koj daim npav NFC?

Qhov no yog raws nraim li RFID thaiv lub hnab nyiaj yuav tsum tiv thaiv. Lub tswv yim yog tias ib tus neeg tuaj yeem tuav lawv cov NFC nyeem ntawv ze rau koj lub hnab nyiaj thiab luam koj daim npav. Tom qab ntawd lawv tuaj yeem muaj lub cuab yeej rov ua dua cov ntaub ntawv RFID rau kev them nyiaj.


Puas yog RFID tiv thaiv hnab nyiaj tsim nyog?

Tsis muaj qhov tsis ntseeg tias lub tswv yim tom qab RFID thaiv daim npav yog qhov ruaj khov. Hauv xyoo 2012, kev ua qauv qhia txog yuav ua li cas lub xov tooj Android tuaj yeem wirelessly nyiag credit card cov ntsiab lus ua rau tsis muaj leej twg tsis ntseeg txog qhov kev hem thawj. Qhov teeb meem yog, hom kev tawm tsam no tsis zoo li tshwm sim hauv cov qus.

Nws ua rau kev nkag siab tias NFC skimming tuaj yeem siv los tiv thaiv cov hom phiaj muaj txiaj ntsig siab nqa cov ntaub ntawv tseem ceeb, tab sis nws tsis tsim nyog taug kev ncig lub khw muaj neeg coob nyiag cov ntaub ntawv credit card los ntawm cov neeg tsis paub. Tsis tsuas yog muaj kev pheej hmoo ntawm lub cev tiag tiag los ua qhov kev cuam tshuam tshwj xeeb rau pej xeem, tab sis nws tseem yooj yim dua los nyiag cov ntaub ntawv credit card siv malware lossis phishing cov tswv yim.

Raws li ib tus neeg tuav daim npav, koj tseem raug tiv thaiv tiv thaiv daim npav rho nyiaj los ntawm cov neeg siv daim npav, tsis muaj leej twg, rau peb txoj kev paub, xav tau RFID thaiv lub hnab nyiaj kom tsim nyog. Yog li, qhov zoo tshaj plaws, koj tuaj yeem zam qhov tsis yooj yim me ntsis thaum cov nyiaj raug nyiag lawm.

Yog tias koj yog lub hom phiaj muaj txiaj ntsig zoo, xws li cov neeg ua haujlwm nrog daim npav nkag mus rau cov khoom muaj txiaj ntsig lossis cov khoom muaj txiaj ntsig, nws yog qhov zoo los siv RFID thaiv cov ntaub ntawv lossis hnab nyiaj.

Yog li, RFID thaiv lub hnab nyiaj yog tsim nyog vim tias qhov kev tawm tsam qis no tuaj yeem siv rau koj. Tab sis peb tsis xav tias qhov no yuav tsum yog qhov kev txiav txim siab thaum xaiv koj lub hnab nyiaj tom ntej tshwj tsis yog tias koj muaj kev pheej hmoo siab. Tom qab ntawd ib zaug ntxiv, qhov zoo tshaj plaws RFID thaiv cov hnab nyiaj kuj yog cov hnab nyiaj zoo. Yog li vim li cas ho tsis?
