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

Ibhakhodi engu-2D (izinhlangothi ezimbili) yisithombe esinesithombe esigcina ulwazi ngokuvundlile njengoba kwenza amabhakhodi anohlangothi olulodwa, kanye nangokuma mpo. Ngenxa yalokho, umthamo wokugcina wamabhakhodi we-2D uphakeme kakhulu kunamakhodi e-1D. Ibhakhodi eyodwa ye-2D ingagcina izinhlamvu ezifika kwezi-7,089 esikhundleni somthamo wezinhlamvu ezingu-20 zebhakhodi ye-1D. Amakhodi okuphendula okusheshayo (QR), anika amandla ukufinyelela kwedatha okusheshayo, awuhlobo lwebhakhodi ye-2D.
Ama-smartphones e-Android ne-iOS asebenzisa amabhakhodi e-2D kuzikena zawo zebhakhodi ezakhelwe ngaphakathi. Umsebenzisi uthwebula ibhakhodi ye-2D ngekhamera ye-smartphone yakhe, futhi umfundi owakhelwe ngaphakathi uhumusha i-URL efakwe ikhodi, eholela umsebenzisi ngqo kuwebhusayithi efanelekile.
Ibhakhodi eyodwa ye-2D ingabamba inani elibalulekile lolwazi endaweni encane. Lolu lwazi lwembulwa kumthengisi, umphakeli noma ikhasimende lapho ikhodi iskenwa izikena zezithombe ze-2D noma amasistimu okubona.
Ulwazi lungase luhlanganise:Igama lomkhiqizi,Iqoqo/Inombolo yenkatho,Isisindo somkhiqizo,Sebenzisa / okungcono kakhulu ngaphambi kosuku,I-ID yoMkhulisi, inombolo ye-GTIN,Inombolo yomkhiqizo,Intengo

Izinhlobo zamabhakhodi e-2D

Kunezinhlobo eziyinhloko zeIskena sebhakhodi ye-2Duphawu: GS1 DataMatrix,QR code,PDF417
I-GS1 DataMatrix ifomethi yebhakhodi ye-2D evame kakhulu. I-Woolworths okwamanje isebenzisa i-GS1 DataMatrix kumabhakhodi ayo e-2D.
Amabhakhodi e-GS1 Datamatrix 2D ayizimpawu ezihlangene ezakhiwe amamojula ayisikwele. Zidumile ngokumaka izinto ezincane ezifana nemikhiqizo emisha.

1.Ukuphula i-GS1 DataMatrix

1.Izingxenye ezihlukene: iphethini yesitholi esetshenziswa isithwebuli ukuze sithole uphawu, kanye nedatha efakwe ikhodi
2.Inani elilinganayo lemigqa namakholomu
3.Ukukhanya 'kwesikwele' ekhoneni eliphezulu kwesokudla
4.Ingakwazi ukufaka ikhodi yedatha yobude obuguquguqukayo - usayizi wophawu uyahlukahluka kuye ngenani ledatha efakwe ikhodi
5.Ingakwazi ukufaka ikhodi kufika ezinhlamvini zamagama nezinombolo ezingu-2335 noma izinombolo ezingu-3116 (nge-squareform)

2.QR amakhodi

Amakhodi e-QR asetshenziselwa ngokuyinhloko ukuxhuma kumasayithi e-URL futhi okwamanje awasetshenziselwa indawo yokuthengisa. Zivame ukusetshenziselwa ukupakisha okubhekene nabathengi, ngoba zingafundwa ngamakhamera we-smartphone.
Ngokusebenzisa i-GS1 Digital Link, amakhodi e-QR angasebenza njengamabhakhodi asetshenziswa kaningi avumela kokubili ukusebenzelana kwabathengi nokubheka amanani, aqede isidingo samakhodi amaningi athatha isikhala sokupakisha esibalulekile.

3.PDF417

I-PDF417 iyibhakhodi engu-2D engagcina idatha kanambambili ehlukahlukene, okuhlanganisa izinhlamvu ze-alphanumeric nezikhethekile. Ingakwazi futhi ukugcina izithombe, amasiginesha nezigxivizo zeminwe. Ngenxa yalokho, ukuqinisekiswa kobunikazi, ukuphathwa kwempahla kanye nezinsizakalo zokuthutha kuvame ukuzisebenzisa. Ingxenye ye-PDF yegama layo isuka egameni elithi "ifayela ledokhumenti ephathekayo." Ingxenye ethi "417" ibhekisela emigoqweni yayo emine nezikhala ezihlelwe ngaphakathi kwephethini ngayinye, ehlanganisa izinhlamvu ezingu-17.

Asebenza kanjani amabhakhodi?

Kafushane nje, ibhakhodi iyindlela yokuhlanganisa ulwazi lube yiphethini ebonakalayo (leyo migqa emnyama nezikhala ezimhlophe) engafundwa umshini (isithwebuli sebhakhodi).
Inhlanganisela yamabha amnyama namhlophe (ephinde abizwe ngokuthi ama-elementi) imelela izinhlamvu zombhalo ezihlukene ezilandela i-algorithm emiswe ngaphambilini yaleyo bhakhodi (okuningi ngezinhlobo zamabhakhodi kamuva). Aisithwebuli sebhakhodiuzofunda le phethini yamabha amnyama namhlophe bese uwahumushela emgqeni wokuhlola ongawuqonda uhlelo lwakho lokudayisa lendawo yokuthengisa.

Uma unentshisekelo noma umbuzo ngesikhathi sokukhetha noma ukusetshenziswa kwanoma iyiphiisithwebuli sekhodi ye-qr, wamukelekile kuXhumana nathi!MINJCODEizibophezele ocwaningweni nasekuthuthukisweni kobuchwepheshe besithwebuli sekhodi yebha kanye nemishini yokufaka isicelo, inkampani yethu ineminyaka eyi-14 yesipiliyoni sembonini emikhakheni yobungcweti, futhi iye yaqashelwa kakhulu iningi lamakhasimende!
