Yuav Ua Li Cas Tsis Ncaj Ncees Teeb Meem Ua Haujlwm?

(Suav teb) Creator Tech Co., Ltd | Updated: May 15, 2018

Kev hu ua ntse ntse nruab ntug muaj feem xyuam nrog kev sib cuag ntse tshuab. Zoo li kev sib cuag ntse ntse tshuab, cov ntaub ntawv khaws cia rau ntawm ib lub nti teeb nyob rau hauv daim npav tsis cuag. Txawm li cas los xij, tsis zoo li daim npav ntsej muag, lub hwj huam nrog rau daim card thiab cov ntaub ntawv sib hloov ntawm daim npav thiab nyeem ntawv yog tsis siv cov neeg siv, siv cov khoom sib nqus lossis electromagnetic teb rau ob leeg fais fab daim card nrog rau cov ntaub ntawv sib pauv nrog tus nyeem ntawv.

Daim npav tiv tauj tsis muaj lub kav hlau txais xov nyob hauv lub hnab yas ntawm daim card (los yog hauv ib qho chaw tseem ceeb, saib los yog lwm daim ntawv). Thaum muab daim card coj los rau hauv lub tshuab electromagnetic ntawm tus nyeem ntawv, lub nti ntawm daim card yog powered. Thaum chip raug siv, ib qho wireless communication protocol yog pib thiab tsim ntawm daim card thiab tus nyeem ntawv rau kev hloov ntaub ntawv.

Cov nram qab no plaub kev piav qhia ntawm qib siab qhov sib lawv liag ntawm cov xwm txheej tshwm sim uas tshwm sim thaum ib daim npav cuag tsis nyob ze ze ntawm ib tus neeg nyeem ntawv:

Zog hloov mus rau daim npav rau kev siv hluav taws xob (integrated chip)

Lub sijhawm teeb liab hloov

Kev hloov cov ntaub ntawv rau cov ntse tsis cuag

Cov ntaub ntawv hloov tawm ntawm daim npav tsis cuag

Yog li, thaum muaj daim npav los ntawm ntau qhov chaw ntawm lub tshuab electromagnetic ntawm qhov yuav tsum tau muaj, daim card yuav tau txais kev pab, npaj rau kev sib txuas lus nrog tus nyeem ntawv. Txij li cov xov tooj hu tsis tau hu rau hauv qhov FAQ no raws li ISO / IEC 14443 tus qauv, qhov no yog 13.56 MHz thiab tus nyeem ntawv uas ua tiav nrog rau tus qauv yuav muaj qhov qhib ua kom pom (thaj tsam) txog 4 ntiv (kwv yees li 10 centimeters). Hauv lwm lo lus, daim card yuav tsum tsis pub dhau 10 centimeters ntawm tus nyeem ntawv rau nws kom zoo; Txawm li cas los xij, txoj kev sib txuas lus rau kev sib txuas lus rau daim card yuav tsum yog nyob ntawm seb muaj ntau yam xws li lub hwj chim ntawm tus nyeem ntawv, lub xov tooj ntawm tus nyeem ntawv thiab lub kav hlau ntawm daim npav.
