A: 2D ua barcode scanning thev naus laus zis siv cov qauv, cov duab, thiab cov dots los encrypt cov ntaub ntawv ob leeg horizontally thiabvertically. Thaum 1D cov lej feem ntau muaj 20 txog 25 cim, 2D barcodes cov tuaj yeem muaj 2, 000 tus cim lossis ntau dua 2D ua cov lej suav nrog QR code, PDF417, thiab DataMatrix.
Hauv qhov no, dab tsi yog 2d scanner?
A 2D ua barcode lub tshuab luam ntawv tuaj yeem txhais cov lej ob-seem, uas khaws cov ntaub ntawv hauv ob qhov ntev, ntau dua li tsuas yog ua kab dub thiab dawb.
Ntxiv mus, dab tsi yog qhov zoo ntawm 2d barcodes? Cov lag luam me xav ua kom muaj kev cuam tshuam loj nrog cov neeg siv khoom tuaj yeem siv 2D barcodes cov . 2D barcodes tuaj yeem suav nrog cov ntaub ntawv ntau ntxiv hauv tus lej ntau dua li lawv 1D cov khoom sib xws, zoo li tus nqi, kom muaj nuj nqis, webaddress lossis txawm tias muaj duab.
Hais txog qhov no, qhov sib txawv ntawm QR code thiab 2d barcode yog dab tsi?
Lawv me dua tab sis tuav cov ntaub ntawv ntau dua li 1D barcode (cov yam ntxwv ntawm kab). Cov ntaub ntawv tseem tau suav nrog ob qho qauv kab rov tav thiab ntsug tab sis tau nyeem hauv ob qhov ntev. QR cov lej zoo tshaj 2D ua barcodes hauv cov ntsiab lus ntawm lawv ntau txoj haujlwm. QR cov lej tuaj yeem tuav cov ntaub ntawv ntau ntxiv tias dab tsi barcodes tuaj yeem ua tau.
Dab tsi yog 2d scanner siv rau?
2D ua thiab 3D Cov tshuab luam ntawv 2D scanners feem ntau yog siv luam cov ntaub ntawv lossis duab, tab sis kuj tuaj yeem yog siv los tsim a 2D ua duab ntawm lwm yam khoom ib yam nkaus.

Dab tsi yog qhov txawv ntawm qhov ua tau zoo thiab cov khoom lag luam teb thiab cov ntsiab lus ntawm kev lag luam uas txhua qhov ua haujlwm zoo tshaj?
Lub tuam txhab muaj peev xwm ua kom tau raws li cov neeg siv khoom xav tau raws sijhawm yog hu ua Kev Ua Haujlwm Zoo, thaum ua haujlwm tau zoo yog lub tuam txhab muaj peev xwm xa khoom raws li tus neeg siv khoom xav tau nrog tsawg kawg ntawm cov khoom siv raw, kev ua haujlwm thiab tus nqi
Dab tsi yog qhov txawv ntawm qhov point thiab nonpoint qhov chaw ntawm dej paug?
Piv txwv li, cov dej tso tawm los ntawm cov chaw tsim khoom lag luam ntawm qee yam lossis cov chaw kho dej khib nyiab. Cov chaw uas tsis yog cov ntsiab lus suav nrog kev khiav tawm ntawm thaj av ua liaj ua teb uas tuaj yeem ntxuav cov chiv lossis lwm yam tshuaj rau hauv pas dej lossis dej ntws - qhov no yuav tshwm sim ntau txhiab square kilometers
Dab tsi yog qhov txawv ntawm qhov rov qab los ntawm peev thiab rov qab los ntawm peev?
Ua ntej, qee qhov kev txhais. Rov qab los ntawm peev ntsuas qhov rov qab uas qhov kev nqis peev ua rau cov neeg koom nrog peev. Rov qab los ntawm peev (thiab ntawm no Idiffer nrog qee cov ntsiab lus) yog thaum tus neeg ua lag luam tau txais ib feem ntawm nws cov peev txheej qub rov qab - suav nrog cov nyiaj tau los ntawm cov nyiaj tau los - los ntawm kev nqis peev
Dab tsi yog qhov txawv ntawm qhov cuam tshuam qhov (socket) thiab lub qhov (socket) pa?
Rau kuv qhov kev paub qhov sib txawv yog nqes mus rau cov khoom siv Qhov saum npoo-hardening ua rau muaj kev cuam tshuam cov qhov (socket) kom nqus tau qhov hloov pauv tam sim ntawd (aka 'kev cuam tshuam') zoo dua. Nrog rau kev cuam tshuam txaus txaus, lub qhov (socket) tsis tu ncua tuaj yeem tawm ntawm cov duab vim tias cov hlau siv muaj softer
Dab tsi yog qhov txawv ntawm qhov kev thov thiab qhov xav tau ntawm cov khoom hais tias mis nyuj?
Dab tsi yog qhov txawv ntawm qhov kev thov thiab qhov xav tau ntawm cov khoom, hais mis nyuj? Kev xav tau yog kev sib raug zoo ntawm ntau tus nqi thiab qhov xav tau ntawm cov nqi ntawd. Kev xav tau ntawm cov mis nyuj yog qhov kev sib raug zoo ntawm tus nqi sib txawv ntawm cov mis nyuj thiab qhov xav tau ntawm cov nqi ntawd
