Yintoni ibhakhowudi ye-1D kunye ne-2D yebhakhowudi?

Kuwo wonke amashishini, iilebhile zebhakhowudi ozisebenzisayo ukuchonga iimveliso kunye nempahla yakho zibalulekile kwishishini lakho. Ukuthotyelwa, ukuzazisi kwebhrendi, ulawulo olusebenzayo lwedatha/ye-asethi kufuna ukuleyibheli okusebenzayo (kwaye kuchanekile). Umgangatho wokuleyibheli kunye neziphumo zoshicilelo lokusebenza kakuhle.Kufuneka wazi uhlobo lwebhakhowudi kungekuphela nje ukufumanisa oko kusebenza ngcono ngeemveliso zakho kodwa ukuze ukwazi ukumisela obunye ubuchwephesha obuxhasayo (abashicileli, iiskena, abafundi) eziza kukunika isisombululo esibanzi sebhakhowudi yeshishini lakho lonke.

Mna: yintoni aIbhakhowudi ye-1D

A: Ibhakhowudi ye-1D (eyaziwa ngokuba yikhowudi yomgca) yipatheni ebonakalayo emnyama namhlophe, usebenzisa imigca yobubanzi obuguquguqukayo kunye nezithuba zolwazi lwe-encoding. Olo lwazi - olufana namanani okanye ezinye iimpawu zebhodi yezitshixo - ifakwe ngekhowudi ngokuthe tye ukusuka ekhohlo ukuya ekunene. Iibhakhowudi ze-1D zibamba inani eliqingqiweyo labalinganiswa, ngokwesiqhelo 20-25. Ukuze wongeze amanani amaninzi, ibhakhowudi kufuneka ibe nde. Ezona ziqhelekileyo iikhowudi ze-1D zezo khowudi ze-UPC eziqhelekileyo ezifumaneka kwigrosari kunye nezinto zabathengi. Ibhakhowudi ye-1D ixhomekeke kuqhagamshelwano lwesiseko sedatha ukuze ibe nentsingiselo; emva kokuba iskena sifunde amanani kwikhowudi, kufuneka aqhagamshelwe emva kwimveliso okanye umhla wexabiso, okanye olunye ulwazi.

Q:Yintoni naIbhakhowudi ye-2D?

A:2D ibhakhowudi iskena kukurekhoda ulwazi kunye namanani ejiyometri asasazwa emnyama namhlophe ngokomthetho othile.2D barcodes zingasetyenziselwa ukuphawula izinto ezincinci kakhulu apho ileyibhile yebhakhowudi yemveli ingayi kufaneleka - cinga ngezixhobo zotyando okanye iibhodi zesekethe ngaphakathi. yekhompyutha.Xa kufikwa kukhetho lwabathengi, iibhakhowudi ze-2D zihlala zikhethwa ngabantu ngenxa yolwazi oluninzi olunokuthi lubanjwe yibhakhowudi ye-2D xa kuthelekiswa ne-1D.
