SAM card (Secure Access Module) yog lub hauv paus ntawm kev tswj hwm kev ruaj ntseg hauv daim npav ntse ntse. Ib daim npav SAM yog ib daim npav tshwj xeeb CPU uas khaws cov yuam sij thiab qhov encryption thiab decryption algorithms.
Muaj ntau hom SAM cards:
Post: Terminal kev ruaj ntseg tswj module, feem ntau yog siv rau kev txiav tawm micropayment.
PEB YOG: Ib manufacturers (txoj hau kev) SAM daim npav siv rau kev txheeb xyuas cov khoom siv.
ISAM: siv rau recharge.
Hauv kev siv tshwj xeeb, nws yuav muaj ntau haiv neeg. Piv txwv li, Qee cov khoom siv tau lees paub tsis yog nrog ESAM phaib, tab sis nrog tshwj xeeb modules. Raws li qhov tshwm sim, muaj qhov teeb meem uas cov yuam sij tau siv hauv software, thiab tej zaum yuav muaj qhov tseem ceeb, Thiab ib txoj hauv kev los daws cov teeb meem no yog khaws ntau cov yuam sij ntawm cov yuam sij thiab qhia ib txheej ntawm cov yuam sij hauv tus lej.
Cov ntawv tshaj tawm ntawm daim npav dog dig feem ntau siv cov txheej txheem ntawm encrypting lub cim card tus lej nrog tus yuam sij.
Ib yam li daim npav ID ntawm daim npav nyeem ntawv, Daim npav sam thiab daim npav nyeem yuav raug suav tias yog ib qho, thiab sam card yuav tsum siv rau uploading, Hloov kho, thiab lub hwj chim-ntawm kev pom zoo ntawm daim npav nyeem ntawv. Sam phaib feem ntau ntsia rau ntawm cov khoom seem ntawm Smart Cards, Raws li kev ruaj ntseg tswj ntawm Smart Card Terminals, Yuav kom ua tiav kev ua raws li kev lees paub ntawm cov khoom lag luam thiab phaib, thiab tuaj yeem siv dav siv hauv nroog ib daim npav rho nyiaj, Kev tsim kho ib daim npav ib daim npav, Tus Paub Txog Tus Kheej, Kev Tswj Xyuas Kev Ruaj Ntseg, rov ntxiv, Kev yuav khoom me me thiab lwm daim ntawv thov.
Hauv daim npav ntse chaw tsim khoom tuaj yeem ntim RFID nti ntau lawm LF / HF / UHF nti daim npav los ntawm cov khoom siv PHA
