1.Siv ceeb
3.1 Txuas daim npav nyeem ntawv rau PC lossis davhlau ya nyob twg los ntawm USB interface
3.2 Lub teeb ntsuab thiab lub teeb liab liab rau, ces hu rau buzzer .Nws yuav ua rau lub teeb liab thiab buzzer tawm tom qab 0.5s, tom qab ntawd nws yuav nyob hauv qhov xwm txheej.,
3.3 Thaum cov hlau nplaum daim npav tau swb thiab cov ntaub ntawv raug, buzzer yuav lub suab thiab 3 thib ob tawm .Txawm li ntawd, lub teeb liab yuav nyob rau thiab buzzer bilnk peb lub sijhawm (ntu sib nrug yog 1s), tom qab ntawd nkag mus rau hauv qhov xwm txheej txaus ntshai.
3.4 los so daim npav nyeem ntawv thiab yuav pom cov ntaub ntawv.
2.Kev Paub:
Daim npav sib nqus yog daim npav zoo li daim ntawv sib nqus cov ntaub ntawv nruab nrab uas siv cov khoom siv hlau nplaum los sau cov cim thiab cov ntaub ntawv digital rau kev txheeb xyuas lossis lwm lub hom phiaj. Daim npav sib nqus yog tsim muaj lub zog siab, siab kub tiv taus cov yas lossis cov ntawv lo-cov yas. Nws yog noo-pov thawj, hnav-resistant thiab hloov tau. Nws yog qhov yooj yim los nqa thiab ruaj khov thiab txhim khu kev qha. Piv txwv li, daim npav bank peb siv yog ib daim npav muaj zog tshaj plaws.
Daim npav sib nqus tau yooj yim siv, pheej yig hauv tus nqi thiab siv dav. Nws tuaj yeem siv los ua daim npav rho nyiaj, ntawv nyiaj hauv tuam txhab, npav npav hauv av, npav npav, npav npav, npav npav, npav npav, ntawv npav ua si hluav taws xob, daim pib, daim pib pa thiab ntau daim npav thauj nqi. Niaj hnub no peb siv cov npav sib nqus rau ntau lub sijhawm, xws li noj mov hauv chaw noj mov, khw hauv khw, noj npav, hu xov tooj, nkag mus hauv thaj chaw tswj, thiab lwm yam.
Lub npe lus Askiv: daim npav nplaum
Ib daim npav-zoo li cov hlau nplaum nruab nrab uas koom tes nrog ntau daim npav nyeem ntawv. Daim npav sib nqus yog daim npav uas siv cov nqa khoom nqa hlau los sau cov ntaub ntawv uas qhia txog tus kheej lossis lwm yam kev siv.
Daim npav sib nqus muaj peev xwm muab faib ua peb hom: PET card, PVC card thiab card card.
Nyob ntawm cov qauv ntawm cov sib nqus txheej, nws muaj peev xwm muab faib ua cov npav sib nqus thiab daim npav npuag sib nqus.
Daim npav hlau nplaum muaj lub hnab yas thiab daim hlau nplaum txuas nrog rau nws. Kev sib nqus sib nqus tau muaj peb kab rau khaws cov ntaub ntawv. ISO qhia meej meej cov yam ntxwv cuam tshuam ntawm cov npav sib nqus, raws li tau piav qhia hauv qab no:
l ISO7810 qhia txog lub cev lub cev cov yam ntxwv ntawm daim npav hlau nplaum muaj xws li cov khoom siv, kev tsim kho thiab qhov ntev ntawm daim npav. Feem ntau qhov loj me ntawm cov hlau nplaum stripe daim npav yog 85.5 X 54 X 0.76 (hli);
Sib nqus sawb khiav
Muaj 3 txoj kab sib chaws ntawm cov khoom sib nqus. Ntu 1, khiav 2, thiab khiav 3 yog nyeem / sau khiav, uas tuaj yeem nyeem lossis sau ntawv thaum siv.
Txoj Kab 1 tuaj yeem sau tus lej (0-9), ntawv (AZ), thiab lwm cov cim (xws li lub cim, cov cim cais, thiab lwm yam), mus txog 79 tus lej lossis cov tsiaj ntawv.
Cov cim sau ntawm lem 2 thiab 3 tuaj yeem tsuas yog tus lej (0-9). Ntu 2 tuaj yeem kaw mus txog 40 cim, thiab kab 3 tuaj yeem kaw mus txog 107 tus cim.
