Cov hom thiab kev ua haujlwm ntawm ntse IC daim npav dej txias meter
IC daim npav dej txias (IC daim npav ntsuas dej rau lub sijhawm luv luv) yog ib hom dej ntsuas nrog kev ua haujlwm them ua ntej, uas yog ua raws li cov ntsuas dej txias rau lub teeb liab ntsuas cov khoom, nrog daim npav IC yog qhov nruab nrab, nruab nrog tswj thiab hluav taws xob tswj valve. Cov.
1. Hom IC daim npav ntsuas dej.
Raws li kev siv daim npav, muaj ob hom sawv cev:
(1) TM daim npav. TM daim npav yog ib hom ntawm cov ntaub ntawv txauv cov ntaub ntawv ywj siab tsim thiab tsim los ntawm lub tuam txhab Dallas nrog cov tswv cuab kev ywj pheej ntiag tug cov cai. Nws muaj hom phiaj tshwj xeeb thiab nyeem ntawv thiab sau ntawv. Kev sib cuam tshuam thiab nyeem thiab sau ntawv tsis sib thooj nrog thoob ntiaj teb IC daim npav, uas peb feem ntau hu ua IC daim npav. Tam sim no, qee lub tuam txhab tseem siv TM daim npav, tab sis muaj qee qhov kev thov hauv ob peb kev lag luam xws li kev nkag mus tswj.
(2) IC daim npav. Daim npav npav IC muaj peb qhov tshwj xeeb, xws li kev ua qauv thoob ntiaj teb, kev txawj ntse thiab kev nyab xeeb. Txij li xyoo 1987, ISO / IEC 7816 tau tsim tshwj xeeb los ntawm International Standardization Organization rau IC card. Txij thaum ntawd los, ntau tshaj kaum lub tuam txhab tau nqis peev pab rau kev tsim kho thiab tsim daim npav IC, suav nrog Motorola, Thomson, Hitachi, Oki, Toshiba, ntse, AIMEL, Philips, Siemens, etc. IC daim npav thov kev lag luam tau nrawm mus rau ntau yam kev lag luam, xws li nyiaj txiag, kev sib tham, kev kho mob, kev pov hwm, tsheb thauj mus los, thiab lwm yam.
