Sensors Fingerprint sensors feem ntau yog optical sensors thiab semiconductor sensors.Optical sensor feem ntau yog hais txog kev siv cov khoom siv kho qhov muag xws li coms kom tau txais cov ntiv tes.Feem ntau, daim duab yog ua rau tag nrho module hauv kev ua lag luam.Hom sensor no yog tus nqi qis tab sis loj loj, thiab feem ntau yog siv rau hauv cov ntiv tes xauv, ntiv tes nkag mus tswj thiab lwm yam khoom.Semiconductor sensors feem ntau yog monopolized los ntawm cov tuam txhab ntiv tes sensor xws li Swedish fingerprint cards.Lawv muab faib ua hom so-on thiab hom nto.Nws tus nqi kuj siab, tab sis nws cov kev ua tau zoo tseem zoo.Nws feem ntau yog siv rau hauv cov haujlwm tseem ceeb xws li kev lis kev cai, tub rog, thiab tuam txhab nyiaj.Niaj hnub no, nrog tib neeg kev paub txog hauv tsev thiab kev txhim kho kev paub txog kev ruaj ntseg hauv tsev hais plaub, ntau thiab ntau lub tuam txhab siv semiconductor nto sensors rau cov pej xeem, thiab cov neeg siv kev paub kuj zoo dua.Cov khoom me me, tus nqi qis, tab sis qhov kev paub tsis zoo.Qhov ceev thiab kev taw qhia ntawm scraping muaj feem xyuam rau cov nyhuv.Fingerprint module Raws li lub hauv ntej kawg ntawm kev lag luam saw, cov tuam txhab software thiab cov tuam txhab ntiv tes xauv kev tshawb fawb thiab kev txhim kho kev lag luam ntawm Tuam Tshoj muab cov pab pawg ntiv tes.—- Tus ntiv tes tiv thaiv tub sab nyiag xauv manufacturers
Feem ntau ntawm cov qauv no tau raug xa los ntawm txawv teb chaws rau kev txhim kho ntxiv thiab muab qhov chaw sib txuas hauv nruab nrab.Tsuas yog tom qab kev txhim kho theem nrab tuaj yeem ua tus ntiv tes module tiag tiag ua lub luag haujlwm.Cov sensors ntawm cov ntiv tes xauv yog muab faib ua optical sensors thiab semiconductor sensors.Optical Sensors Siv Optical Sensors kom ntes cov duab ntiv tes Optical sensors ntawm kev ua lag luam feem ntau yog ua tiav module.Qhov zoo ntawm optical sensors yog tus nqi qis thiab muaj peev xwm los tiv thaiv zoo li qub, tab sis vim qhov loj ntawm cov khoom siv kho qhov muag, lawv tsis tuaj yeem txheeb xyuas cov ntiv tes nyob, thiab lawv tsis tuaj yeem txheeb xyuas cov ntiv tes ntub thiab qhuav.Feem ntau siv rau cov ntiv tes xauv thiab ntiv tes qhov rooj txwv, thiab lwm yam. Muaj ob hom semiconductor sensors: hom so-on thiab nto hom.Hom nto yog kim dua tab sis muaj kev ua haujlwm tsawg.Feem ntau siv hauv tub rog, tuam txhab nyiaj thiab lwm yam lag luam tseem ceeb.Fingerprint ua ke xauv lub npe semiconductor sensor siv lub hauv paus ntsiab lus ntawm capacitance, hluav taws xob teb, kub thiab siab los sau cov ntiv tes.Forged fingerprint cov ntaub ntawv tsis tuaj yeem lees paub los ntawm semiconductor sensors, yog li semiconductor fingerprint chips kim, tab sis lawv cov kev ruaj ntseg yog siab heev.
