What Is a 2D barcode and How Does It Work?

Ibhakhowudi ye-2D (ezimbini-ezimbini) ngumfanekiso womzobo ogcina ulwazi ngokuthe tye njengoko zisenza iikhowudi ezinedimensional enye, ngokunjalo ngokuthe nkqo. Ngenxa yoko, umthamo wokugcinwa kweebhakhowudi ze-2D uphezulu kakhulu kuneekhowudi ze-1D. Ibhakhowudi enye ye-2D inokugcina ukuya kuthi ga kwiimpawu ezingama-7,089 endaweni yomthamo wamagama angama-20 webhakhowudi ye-1D. Iikhowudi zokuphendula ngokukhawuleza (QR), ezenza ukufikelela kwedatha ngokukhawuleza, luhlobo lwebhakhowudi ye-2D.
Ii-smartphones ze-Android kunye ne-iOS zisebenzisa iibhakhowudi ze-2D kwizikena zebhakhowudi ezakhelwe ngaphakathi. Umsebenzisi ufota ibhakhowudi ye-2D kunye nekhamera ye-smartphone, kwaye umfundi owakhelwe ngaphakathi utolika i-URL ekhowudiweyo, ekhokelela umsebenzisi ngqo kwiwebhusayithi efanelekileyo.
Ibhakhowudi ye-2D enye inokubamba isixa esibalulekileyo solwazi kwindawo encinci. Olu lwazi lutyhilwa kumthengisi, umthengisi okanye umthengi xa ikhowudi iskenwa nge-2D imaging scanners okanye iinkqubo zombono.
Ulwazi lunokubandakanya: Igama lomvelisi, Ibhetshi / inombolo yeqashiso, Ubunzima bemveliso, Sebenzisa ngokugqwesileyo ngaphambi komhla, Isazisi soMvelisi, inombolo yeGTIN, inombolo yesiriyeli, ixabiso

Iindidi ze-2D zebhakhowudi

Kukho iintlobo eziphambili zeIskena sebhakhowudi ye-2Disimboli: GS1 DataMatrix, ikhowudi yeQR, PDF417
I-GS1 DataMatrix yeyona fomati yebhakhowudi ye-2D eqhelekileyo. UWoolworths ngoku usebenzisa i-GS1 DataMatrix kwiibhakhowudi zayo ze-2D.
GS1 Datamatrix 2D iibhakhowudi ziisimboli compact ezenziwe iimodyuli ezisikwere. Ziyaziwa ngokumakisha izinto ezincinci ezifana nemveliso entsha.

1.Ukwaphula i-GS1 DataMatrix

1.Ukwahlula iindawo: ipateni yomfumani esetyenziswa sisikena ukufumana isimboli, kunye nedatha ekhowudiweyo.
2.Nani inani lemiqolo kunye neekholamu
3.Ukukhanya 'isikwere' kwikona ephezulu ngasekunene
4.Ingakwazi ukufaka ikhowudi yedatha yobude obuguquguqukayo - ubungakanani besimboli buyahluka ngokwenani ledatha ekhowudiweyo
5.Ingakwazi ukufaka iikhowudi ukuya kuthi ga kuma-2335 oonobumba bealphanumeric okanye amanani angama-3116 (nge-squareform)

Iikhowudi ze-QR ze-2

Iikhowudi ze-QR zisetyenziselwa ukudibanisa kwiindawo ze-URL kwaye okwangoku azisetyenziselwa indawo yokuthengisa. Zihlala zisetyenziselwa ukupakishwa okujongene nabathengi, kuba zinokufundwa ziikhamera ze-smartphone.
Ukusebenzisa i-GS1 Digital Link, iikhowudi ze-QR zinokusebenza njengeebhakhowudi ezininzi ezivumela ukubandakanyeka kwabathengi kunye nokujonga ixabiso, ukuphelisa imfuno yeekhowudi ezininzi ezithatha indawo yokupakisha ebalulekileyo.

3.PDF417

I-PDF417 yibhakhowudi ye-2D enokugcina iinkcukacha ezahlukeneyo zokubini, kuquka ialphanumeric kunye neempawu ezizodwa. Iyakwazi nokugcina imifanekiso, imisayino kunye neminwe. Ngenxa yoko, ukuqinisekiswa kwesazisi, ulawulo lwempahla kunye neenkonzo zothutho zihlala zizisebenzisa. Inxalenye yePDF yegama layo livela kwigama elithi "ifayile yoxwebhu oluphathwayo." Inxalenye ethi "417" ibhekiselele kwimivalo yayo emine kunye nezithuba ezicwangciswe ngaphakathi kwipateni nganye, equlathe oonobumba abali-17.

Zisebenza njani iibhakhowudi?

Ngamafutshane, ibhakhowudi yindlela yokufaka ulwazi kwipatheni ebonakalayo (loo migca emnyama kunye nezithuba ezimhlophe) ezinokuthi zifundwe ngumatshini (i-scanner yebhakhowudi).
Indibaniselwano yeebar ezimnyama nezimhlophe (ekwabizwa ngokuba ziziqalelo) imele abalinganiswa abahlukeneyo beteksti abalandela ialgorithm esele isekwe yaloo barcode (ngaphezulu kwiindidi zebhakhowudi kamva). Aiskena sebhakhowudiuya kufunda lo mzekelo wemivalo emnyama namhlophe kwaye uyiguqulele kumgca wokuvavanya ukuba indawo yakho yokuthengisa yokuthengisa inokuqonda.

Ukuba unomdla okanye umbuzo ngexesha lokukhetha okanye ukusebenzisa nayiphi naIskena sekhowudi ye-qr, Wamkelekile kwiQhagamshelana nathi!MINJCODEuzibophelele kuphando kunye nophuhliso lwetekhnoloji ye-barcode scanner kunye nezixhobo zokusebenza, inkampani yethu ineminyaka eyi-14 yamava oshishino kwiinkalo zobungcali, kwaye iye yamkelwa kakhulu luninzi lwabathengi!
