ʻO ka ʻike manamana lima, ʻo ia kekahi o nā ʻenehana hōʻike biometric, hoʻohana nui i nā ʻokoʻa o ka ʻili o nā manamana lima o nā kānaka, ʻo ia hoʻi, nā kualono a me nā awāwa o ke ʻano.No ka mea, ʻokoʻa ke ʻano o ka manamana lima o kēlā me kēia kanaka, ʻokoʻa nā wahi haʻihaʻi a me nā intersections, , a ʻaʻole i hoʻololi ʻia i ke ola holoʻokoʻa, no laila ua lilo ka ʻike manamana lima i mea hoʻohana nui a ʻoi loa ka ʻenehana i waena o nā ʻenehana biometric.I kēia manawa, ua hoʻohana nui ʻia ka ʻike manamana lima i ka noiʻi hewa, anti-terrorism, palekana aupuni, anti-narcotics, palekana lehulehu, etc. ola.

ʻO ka loina hana o ka ʻike manamana lima he ʻekolu mau hana: ka heluhelu ʻana i nā kiʻi manamana lima, ka unuhi ʻana i nā hiʻohiʻona, a me ka hoʻohālikelike ʻana i nā manamana lima.ʻO nā ʻenehana ʻike manamana lima maʻamau: optical, capacitive, a me ka ultrasonic.

ʻIke ʻike manamana lima

ʻO ka ʻike manamana lima ʻo Optical kahi ʻenehana ʻike manamana lima me ka mōʻaukala lōʻihi.Hoʻohana ia i nā loina o ka refraction māmā a me ka noʻonoʻo e ʻike i nā manamana lima.E ʻokoʻa ke kihi o ka refraction o ke kukui i hoʻokuʻu ʻia ma nā laina like ʻole ma ka ʻili o ka manamana lima a me ka ʻōlinolino o ka mālamalama i ʻike ʻia, ma laila e hōʻiliʻili ai i nā ʻōlinolino like ʻole a me ka pae pouli o ka ʻike kiʻi e hoʻopau i ka hōʻiliʻili manamana lima.
He kiʻekiʻe ko ka poʻe heluhelu fingerprint optical no ke kumu kukui a me ka hoʻopili ʻana ma waena o ka manamana lima a me ka mea ʻike, a koi aku i ka hoʻopili ʻana i ka manamana lima maikaʻi a me ka alignment.No laila, noho pinepine nā modules fingerprint optical i kahi ākea nui a loaʻa kekahi mau koi no ka mahana a me ka haʻahaʻa, a ʻaʻole kūpono loa kona ʻike ʻana.ʻO ka maikaʻi o kēia ʻenehana ʻo ia ke kumu kūʻai haʻahaʻa a kūpono i nā noi ʻike manamana lima maʻamau, e like me nā mīkini hele manamana lima.

ʻO ka ʻike manamana lima Capacitive

ʻOi aku ka paʻakikī o ka ʻike fingerprint capacitive ma mua o ka ʻike fingerprint optical.ʻO kāna kumu ka hoʻohui ʻana i ka ʻike kaomi, ka capacitive sensing, ka thermal sensing a me nā mea ʻē aʻe i loko o kahi puʻupuʻu.Ke paʻi ka manamana lima i ka ʻili o ka puʻupuʻu, e hana ka mea ʻike capacitive kūloko i kahi kiʻi manamana lima e pili ana i ka ʻokoʻa o ka uku (a i ʻole ka ʻokoʻa wela) i hana ʻia e ka piko manamana lima a me ke ala, kahi e pono ai ka pilina maikaʻi ma waena o ka manamana lima a me ka mea ʻike.
ʻO ka maikaʻi o ka hoʻohana ʻana i ka ʻike manamana lima capacitive ʻo ia ke kiʻekiʻe o ke kiʻi, liʻiliʻi ka distortion, a e hele ka hōʻailona uila i ka ʻili make ma ka ʻili o ka manamana lima, no laila hiki ke hoʻokō ʻia ka ʻike kino ola, e hoʻomaikaʻi nui i ka palekana o ka ʻike manamana lima.Eia nō naʻe, loaʻa i ka ʻike manamana lima capacitive kona mau hemahema.Pono nā kiʻi kiʻi manamana lima kiʻekiʻe i nā ʻāpana capacitive kiʻekiʻe, kahi e hoʻonui nui ai i ke kumukūʻai.A no ka hilinaʻi ʻana o ka ʻike manamana lima capacitive ma nā kua a me nā awāwa o ka manamana lima, inā ua haumia ka ʻili o ka manamana lima i ka lepo a i ʻole ka hou, e hoʻololi ia i ka ʻike kikoʻī ma ka ʻili o ka manamana lima, e alakaʻi ana i ka ʻike pololei ʻole.

ʻIke ʻike manamana lima kani kani

ʻO ka ʻike manamana lima kani kani he ʻenehana hou e hoʻohana ana i nā hawewe kani e loaʻa ai ka ʻike manamana lima.Hoʻopuka ka mea ʻike i nā pulse ultrasonic, i hoʻopuehu ʻia a ʻike ʻia i ka wā e hālāwai ai lākou i nā ʻano manamana lima.Loaʻa i ka mea ʻike ka hōʻailona kani ultrasonic i hōʻike ʻia a unuhi i nā hiʻohiʻona manamana lima ma o ka nānā ʻana i nā loli i ka hōʻailona.He haʻahaʻa ko ka poʻe heluhelu manamana lima kani kani no ka hoʻopili ʻana ma waena o ka manamana lima a me ka mea ʻike, no laila hiki iā lākou ke hana inā loaʻa kahi mamao mai ka ʻili manamana lima.ʻO ka maikaʻi o kēia ʻenehana ʻoi aku ka pale ʻana i ka lepo a me nā ʻōpala.He ʻano hana ʻike manamana lima maikaʻi loa ia.Eia naʻe, ʻo ka ʻike ʻana i ka manamana lima kani ultrasonic ʻaʻole me kāna mau hemahema.ʻOi aku ka kiʻekiʻe o ke kumukūʻai o ka ʻike manamana lima kani ultrasonic, a ʻaʻole ia e like me ka ʻike ʻana i ka fingerprint optical a me ka capacitive.ʻAʻole kūpono hoʻi me nā kiʻiʻoniʻoni pale o kekahi mau mea, e kaupalena ʻia ka ʻike ʻana i ka manamana lima ultrasonic.pololei.

Hoʻohui pū ʻia, loaʻa ka ʻike manamana lima optical, capacitive, a me ka ultrasonic i kā lākou pono ponoʻī.ʻO ka ʻike fingerprint capacitive ka mea i hoʻohana nui ʻia i kēia manawa, akā ʻo ka ultrasonic fingerprint recognition ka mea palekana kiʻekiʻe loa.ʻOiai ka haʻahaʻa loa o ka ʻike fingerprint optical, ʻaʻole maikaʻi ka palekana a me ka hana ʻike.

Hāʻawi ʻo Shenzhen Handheld-Wireless Technology Co, Ltd i nā lima paʻa lima a me nā papa i kēia manawa e kākoʻo ana i nā manamana lima capacitive, loaʻa ka hoʻohana ʻana i ke kaiapuni ikaika a me ka anti-counterfeiting kiʻekiʻe.Hiki iā lākou ke hoʻohana nui ʻia i ka palekana o ka lehulehu, ka mālama ʻana i ka lehulehu, ka palekana, ka hoʻokele mana, etc.
