Ob-dimensional code" target="_blank">Ob-dimensional code tseem hu ua QR Code, thiab lub npe tag nrho ntawm QR yog Quick Teb. Cov ntaub ntawv tseem tuaj yeem sawv cev ntau hom ntaub ntawv.
Ob-dimensional bar code / ob-dimensional bar code (2-dimensional bar code) sau cov ntaub ntawv cim cov ntaub ntawv nrog rau cov duab geometric tshwj xeeb muab faib rau ntawm lub dav hlau (ob-dimensional kev taw qhia) raws li qee txoj cai; Siv cov ntsiab lus ntawm "0" thiab "1" me ntsis ntws uas tsim lub hauv paus ntsiab lus ntawm lub khoos phis tawj, siv ntau cov duab geometric sib raug rau binary los sawv cev rau cov ntawv thiab cov ntaub ntawv xov xwm, tsis siv neeg nyeem los ntawm cov khoom siv duab lossis cov khoom siv photoelectric scanning kom ua tiav kev ua haujlwm tsis siv neeg. ntawm cov ntaub ntawv: nws muaj ib co nta ntawm barcode technology: txhua code system muaj nws cov cim tshwj xeeb teeb; txhua tus cim occupies ib qhov dav; nws muaj qee yam kev pov thawj muaj nuj nqi, thiab lwm yam, tib lub sijhawm, nws kuj muaj cov haujlwm ntawm kev txheeb xyuas cov ntaub ntawv hauv cov kab sib txawv, thiab cov txheej txheem ntawm cov duab sib hloov thiab cov ntsiab lus hloov.
Nta
1. High-density coding, cov ntaub ntawv loj muaj peev xwm: nws tuaj yeem ua raws li 1850 tus tsiaj ntawv loj lossis 2710 tus lej lossis 1108 bytes, lossis ntau dua 500 tus cim Suav, uas yog kaum ob npaug ntau dua li cov ntaub ntawv barcode zoo tib yam.
2. Dav coding ntau yam: lub barcode tuaj yeem encode cov duab, suab, cim, kos npe, ntiv tes thiab lwm yam ntaub ntawv digitized, thiab qhia lawv nrog barcodes; nws tuaj yeem sawv cev ntau yam lus; nws tuaj yeem sawv cev cov ntaub ntawv duab.
3. Muaj zog ua txhaum cai thiab kev kho qhov yuam kev: qhov no ua rau ob sab barcode nyeem kom raug thaum nws yog ib feem puas vim perforation, paug, thiab lwm yam, thiab cov ntaub ntawv tseem tuaj yeem rov qab tau thaum qhov chaw puas mus txog 50%.
4. Kev ntseeg siab ntawm kev txiav txim siab: Nws yog qhov qis dua li qhov kev txiav txim siab ntawm tus lej barcode yuam kev ntawm 2/1000000, thiab qhov yuam kev me ntsis tsis tshaj 1/10000000.
5. Kev ntsuas encryption tuaj yeem qhia tau: kev tsis pub lwm tus paub thiab kev tiv thaiv cuav yog qhov zoo.
6. Tus nqi qis, yooj yim los tsim, thiab ruaj khov.
7. Cov duab, qhov loj thiab qhov sib piv ntawm cov cim barcode tuaj yeem hloov pauv.
8. 2D barcodes tuaj yeem nyeem tau siv laser lossis CCD nyeem ntawv.
