Izinto eziningana okudingeka unake lapho ukhetha isithwebuli somunwe

Into yokuqala okufanele unake lapho ukhetha isithwebuli somunwe yindlela yokuvula nokuqashelwa kwesithwebuli somunwe. Okuvame kakhulu emakethe kungukuvulwa kokuvulwa kweminwe okubonakalayo, ukuvula iminwe yeminwe, kanye nokuvula iminwe ye-ultrasonic. Lezi zintathu ubuchwepheshe obuvuthiwe futhi banokusebenza okuphezulu kwezokuphepha.

Okuthuthuke kakhulu yisithwebuli somunwe we-ultrasonic. Umehluko omkhulu phakathi kwaso kanye nendlela yokuqashelwa yeminwe yendabuko ukuthi okwedlule akudingi inzwa ye-capacive, futhi ukudluliselwa kwe-ultrasonic kungafihlakala ngaphansi kweplastiki, ingilazi kanye nensimbi. Umunwe awudingi ukuthinta ngesikhathi senqubo yokuqashelwa. Isebenzisa amagagasi e-ultrasonic ukuskena izigxivizo zeminwe, ezingangena kwi-dermis yesikhumba ukwakha isithombe somunwe ngezici zeminwe ze-3D. Lobu buchwepheshe busetshenziswa emkhakheni we-Fingerprint Door Locks, ukuqeda imodyuli yekhanda leminwe yesithwebuli somunwe, okungaba lula futhi kube nobuchwepheshe obuningi ngokubukeka. Ngasikhathi sinye, indlela yokuqashelwa yokuxhumana nayo isusa iziphambeko zekhanda lendabuko le-Fingerprint Fingerprint Teed lithinteka kalula ngamabala namabala okujuluka. Inzuzo ukuphepha okuphezulu, kanye nokubi yikhona ukuthi ijubane lokuqashelwa lihamba kancane.

Okwesibili ukuvulwa kwe-capacitive zeminwe. Uhlelo lokuqashelwa kweminwe lwangaphambili lungelokubonwa kweminwe ye-capacive. Isebenzisa kakhulu ingaphezulu lesikhumba somunwe njengesigxobo esisodwa. Imigodi nezigodi (amaphuzu aphezulu futhi aphansi ku-Fingerprint) yakha amanani ahlukile we-Capcacitance ngenxa yamabanga ahlukene avela ebusweni be-chip, ukuze inzwa yokuqashelwa yeminwe ye-chip ithola imininingwane yezithombe zeminwe. Inzuzo ukuthi ijubane lokuqashelwa lishesha kakhulu, futhi inkinga ukuthi ukusebenza kwezokuphepha kulinganiselwe.

Ukuqashelwa kweminwe kwe-Optical Fingerprition: Ukuqashelwa kweminwe kwe-Optical Fingerprint kungubuchwepheshe bokubona abanolwazi olusetshenziswa kakhulu njengamanje. Isebenzisa umunwe obekwe kumalensi abonakalayo, ekhanyiselwe ngumthombo wokukhanya owakhelwe ngaphakathi, okucatshangwe kudivayisi yokushaja, futhi kucutshungulwa yi-chip ye-Fingerprint ukuze ube isithombe sokuqashelwa kweminwe esiningi. Inzuzo ukuqina okuqinile kwezemvelo nokuqina okuhle. Okubi ukuthi kuneziphambeko ezenzeka kumvelo yokuqashelwa.

Into eyodwa okufanele unake ngokukhethekile ukuthi akumele uthenge isithwebuli seminwe esiyinhloko. Lokhu kukhiya kungabona kuphela ama-gullies emdwetshenweni womuntu. Isithwebuli somunwe sizohlukanisa iminwe zibe yizindawo ezincane bese sithwebula iminwe. Uma kungumgodi, imininingwane ingu-0, futhi uma kuyingxenye ebonakalayo, imininingwane ingu-1. Ngale ndlela, lapho sibeka iminwe yethu emshinini weminwe, isithwebuli somunwe siyobona "0" no "1". Lapho ukufana phakathi kwemininingwane eyaziwayo kanye nemininingwane egcinwe ngaphambili ifinyelela ezingeni elithile, isithwebuli seminwe singavulwa. Kuyaziwa ukuthi umnyango ungavulwa ngezinzwane, ezikhathaza ukuphepha.
