Rfid Blocking Sleeve yog dab tsi?

Nrog rau kev txhim kho thev naus laus zis, txhua tus hnav khaub ncaws, zaub mov, vaj tse, thiab kev thauj mus los tau vam khom ntau yam ntawm daim npav. Txhawm rau kom ua tiav kev paub yooj yim raws li kev tswj hwm, txhua daim npav peb tuav muaj RFID chips uas yooj yim rau kev luam theej duab thiab nyeem, uas tseem coj tau ntau yam ntaub ntawv raug nyiag thiab nthuav tawm, tag nrho nthuav tawm peb tus kheej thiab kev ruaj ntseg ntawm cov khoom.

 

Khoom Taw Qhia:

Lub cev tseem ceeb ntawm tus tuav daim npav yog nruab nrog txheej txheej txheej, yog li thaum daim npav muab tso rau hauv chav cia, txheej txheej txheej sab nraud tuaj yeem cais daim npav rho nyiaj, ua rau nws tsis yooj yim rau NFC cov khoom siv kom tau txais daim npav cov ntaub ntawv txawm tias lawv yog. nyob ze ntawm daim npav tiv thaiv ntawm daim npav RFID tsis tiv tauj, ua kom cov ntaub ntawv muaj kev ruaj ntseg zoo.

 

 

Khoom nta:

1.Kev nyab xeeb thiab txhim khu kev qha: RFID shielding npog no yog ua los ntawm cov ntawv tooj liab thiab txhuas hlau txheej txheej, uas tuaj yeem tiv thaiv RFID zoo thiab tiv thaiv cov ntaub ntawv ntiag tug kom zoo tshaj plaws;

2.Siv dav: Customized loj, duab, thiab ntim tsim ntawm RFID shielding tes tsho raws li cov neeg siv khoom xav tau, kom ua tau raws li qhov xav tau ntawm ntau yam ntaub ntawv;

3.Portable: Cov khoom siv yog lub teeb yuag thiab yooj yim nqa.

4.Cov lus qhia rau kev siv: Txoj kev siv yog yooj yim heev. Tsuas tso daim npav uas yuav tsum tau tiv thaiv kom raug rau hauv RFID shielding case los thaiv cov ntaub ntawv RFID tub sab los ntawm daim npav nyob ze lossis ntev.

5.Scope ntawm kev siv: Cov khoom ntiag tug nrog cov khoom siv ntse, xws li credit cards, passports, debit cards, bus cards, ID cards, etc.

 

Yam khoom muaj nuj nqi:

Lub tes tsho RFID kev ruaj ntseg daim npav tuaj yeem pab cov neeg siv tiv thaiv cov neeg txawv teb chaws los ntawm kev nyeem lawv tus kheej IC daim npav hauv txhab nyiaj, daim npav ID, daim npav thauj pej xeem thiab lwm daim npav RFID ntse, thiab tshem tawm tag nrho cov kev pheej hmoo ntawm cov npav hauv txhab nyiaj, cov npav thauj pej xeem raug nyiag thiab swiped, thiab tus kheej ntiag tug. cov ntaub ntawv xau vim NFC daim ntawv thov xws li Alipay Hnab.

 

Txoj Cai Tsim:

RFID daim npav kev ruaj ntseg yog tsim los ntawm Faraday lub hauv paus ntsiab lus. NFC / RFID kev sib txuas lus yog ib qho kev sib txuas lus wireless uas siv hluav taws xob hloov chaw rau cov teeb liab kis. Qhov no electromagnetic teb propagates rau saum npoo ntawm daim npav tiv thaiv uas ua raws li Faraday tawb lub hauv paus ntsiab lus thiab yog "pob tshab" rau sab nraud ntawm daim npav. Txawm li cas los xij, tsis muaj qhov sib txawv ntawm cov hluav taws xob hluav taws xob raug kuaj pom nyob rau hauv lub chamber ntawm cov ntaub ntawv tiv thaiv (vim raws li Faraday lub hauv paus ntsiab lus, lub peev xwm sab hauv yog sib npaug txhua qhov chaw thiab tsis muaj nqi txav). Yog li ntawd, NFC nti hauv daim npav yuav tsis teb rau sab nraud electromagnetic teb kev sib txuas lus.

NFC nti hauv lub tes tsho daim npav kev ruaj ntseg tsis tuaj yeem nqus lub zog xa mus los ntawm NFC daim npav nyeem ntawv, yog li tsis muaj lub zog los qhib nws cov qauv hluav taws xob sab hauv uas xav tau lub zog. Qhov no ua rau nws ua tsis tau rau NFC cov cuab yeej kom tau txais cov ntaub ntawv hauv txhab nyiaj txawm tias nws nyob ze rau IC daim npav hauv txhab nyiaj hauv lub tes tsho tiv thaiv, ua kom muaj kev ruaj ntseg ntawm koj cov ntaub ntawv hauv txhab nyiaj.
