Nkag siab Smart Card Technology Basics
Cov nyiaj them poob haujlwm thiab cov txheej txheem ID tau hloov pauv li cas peb tswj kev lag luam ruaj ntseg thiab kev tswj xyuas hauv cov txheej txheem them nyiaj niaj hnub no. Cov khoom siv qib siab no txuas koj daim npav ntse nti rau lub ntiaj teb digital. Lawv tso cai rau kev sib txuas lus zoo rau ntau yam kev siv, xws li kev thauj mus los hauv pej xeem, chaw nres tsheb, thiab kev lag luam nyiaj txiag.
Dab tsi yog Smart Card Payment Device?
Lub smart card interface unit yog ib qho hluav taws xob uas sib txuas lus nrog cov ntawv ntse uas muaj cov kab sib txuas sib txuas. Koj tuaj yeem pom cov validation terminals nyob rau hauv ntau hom.
Lawv txawv los ntawm cov khoom siv me me USB mus rau cov tshuab sib txuas siab heev. Cov tshuab no yog siv rau hauv lub tsheb npav validators thiab chaw nres tsheb meters. Ntawm Golong, peb tshwj xeeb hauv kev tsim khoom lag luam - qib chip daim npav processors uas lub zog txhim khu kev qha kev them nyiaj sib sau ua ke rau pej xeem kev thauj mus los.
Yuav Ua Li Cas Smart Card Interfaces Ua Haujlwm: Cov Txheej Txheem Txheej Txheem
Tiv tauj vs. Kev sib txuas lus tsis sib cuag
Chip paub tshuab ua haujlwm los ntawm ob txoj hauv kev:
Tiv tauj-raws li Chav nyob: Cov no yuav tsum tau muab lub cev tso rau ntawm daim npav rau hauv qhov chaw ntaus ntawv. Cov hlau hu rau ntawm daim npav nti txuas ncaj qha mus rau lub davhlau ya nyob twg cov khoom txuas. Qhov no tso cai rau kev ruaj ntseg cov ntaub ntawv hloov ntawm qhov ceev mus txog 424 Kbps.
Kev them nyiaj tsis sib cuag: Siv xov tooj cua zaus (RF) thev naus laus zis, cov wireless terminals sib txuas lus los ntawm RFID lossis NFC raws tu qauv. Thaum ib daim npav tuaj txog li 50 hli ntawm lub tshuab kuaj pom, nws ua rau lub zog ntawm daim npav nti. Qhov no pib pauv cov ntaub ntawv.
Kev sib txuas lus raws tu qauv
Lub hauv paus ntsiab lus ua haujlwm ua raws li txheej txheem txheej txheem:
- Lub Hwj Huam Ua Haujlwm: Lub tshuab hluav taws xob sib txuas tsim hluav taws xob hluav taws xob uas ua rau daim npav nti
- Authentication: Cov txheej txheem ruaj ntseg txheeb xyuas daim npav qhov tseeb siv kev sib txuas lus encrypted
- Cov Ntaub Ntawv Sib Pauv: Cov ntaub ntawv ntws ntawm daim npav thiab chav ua haujlwm los ntawm cov txheej txheem txheej txheem xws li ISO 14443 rau daim npav tsis sib cuag
- Transaction Processing: Lub davhlau ya nyob twg ua cov ntaub ntawv tau txais thiab sib txuas lus nrog tus tswv tsev
Smart Card Technology Cheebtsam

Cov ntawv thov hauv Public Transportation thiab Payment Systems
Bus Validation Systems
Transit validators ua lub luag haujlwm tseem ceeb hauv kev caij npav npav niaj hnub. Cov txheej txheem them nyiaj ruggedized no tiv taus ib puag ncig hnyav thaum ua haujlwm ntau txhiab kev lag luam txhua hnub. Cov terminals txhawb ntau txoj hauv kev them nyiaj suav nrog khaws cia - daim npav nqi, kev them nyiaj mobile, thiab cov txiaj ntsig digital.
Chaw nres tsheb Meter kev koom ua ke
Hauv daim ntawv thov chaw nres tsheb, cov khoom siv them nyiaj tsis siv neeg ua kom yooj yim rau kev ua lag luam thaum tuav cov ntaub ntawv ruaj ntseg. Lub tshuab ua haujlwm nrog ntau hom ntawv. Nws kuj tseem txuas tau yooj yim rau kev tswj hwm lub sijhawm tiag tiag - sijhawm saib xyuas thiab txheeb xyuas cov ntaub ntawv.
Access Control thiab Security
Tshaj li kev them nyiaj ua haujlwm, kev nkag mus tswj interfaces muab kev tswj xyuas kev nyab xeeb rau cov cheeb tsam txwv, tshawb xyuas lub sijhawm, thiab kev txheeb xyuas tus kheej. Kev sib txuas lus encrypted ua kom cov ntaub ntawv ncaj ncees thiab tiv thaiv kev nkag mus tsis tau.
