PREPAID SYSTEM INTRODUCTION
Txheej txheem cej luam
IC Card series dej ntsuas dej yog ib hom kev them nyiaj ua ntej thiab ntsuas dej ntse. Nws yog tsim thiab tsim los ntawm peb lub tuam txhab thiab nto moo tsim tuam txhab uas muag ob qho tib si domestic thiab aboard raws li tus txheej txheem thoob ntiaj teb.
Qhov zoo ntawm qhov system
· OEM, cov lus qhia thiab cov txiaj ntsig tuaj yeem hloov kho, thiab lub tuam txhab npe tuaj yeem muab ntxiv rau hauv software.
· Cov ntaub ntawv yuav raug cawm cia tom qab tawm hauv lub cev.
· Yooj yim tswj thiab siv daim npav ua, yooj yim rau kev nug cov ntaub ntawv noj.
· Invoice printing, muab voucher them nyiaj rau cov neeg siv nyob rau hauv daim ntawv feem ntau nyob rau hauv lub zos.
Kev taw qhia luv luv
Lub ntsuas dej prepaid muaj cov tshuab nyeem thiab hluav taws xob. Nws yog siv los tswj cov neeg siv nyiaj ntau dhau los ntawm kev them nyiaj ua ntej nrog daim npav IC. Them ua ntej thiab tom qab ntawd siv dej tshem tawm qhov tsis yooj yim ntawm kev nyeem ntawv ntawm qhov chaw thiab them nyiaj.
