He aha ka barcode 1D a me ka barcode 2D?

Ma waena o nā ʻoihana, he mea koʻikoʻi nā lepili barcode āu e hoʻohana ai e ʻike i kāu huahana a me nā waiwai i kāu ʻoihana. Pono ka hoʻopaʻa inoa ʻana, ka hōʻailona hōʻailona, ​​​​ka ʻikepili maikaʻi / hoʻokele waiwai. Pono ʻoe e ʻike i ke ʻano o nā barcode ʻaʻole wale no ka hoʻoholo ʻana i ka mea e hana maikaʻi me kāu huahana akā no laila hiki iā ʻoe ke hoʻoholo maikaʻi i nā ʻenehana kākoʻo ʻē aʻe (nā mea paʻi, scanners, mea heluhelu) e hāʻawi iā ʻoe i kahi hopena barcode piha no kāu ʻoihana holoʻokoʻa.

N: He aha ka1D barcode

A: ʻO ka barcode 1D (ʻike pū ʻia he code linear) he kumu ʻeleʻele a me ke keʻokeʻo ʻike, e hoʻohana ana i nā laina ākea ākea a me nā hakahaka no ka hoʻopili ʻana i ka ʻike. Hoʻopili ʻia kēlā ʻike - e like me nā helu a i ʻole nā ​​​​ʻano papa keyboard ʻē aʻe - mai ka hema a i ka ʻākau. Loaʻa i nā pāʻālua 1D ka helu palena o nā huapalapala, maʻamau 20-25. I mea e hoʻonui ai i nā helu, pono e lōʻihi ka barcode. ʻO nā pāʻālua 1D maʻamau ʻo ia nā code UPC maʻamau i loaʻa ma nā mea kūʻai a me nā mea kūʻai aku. Hoʻopili ʻia kahi barcode 1D i ka hoʻopili ʻana i ka waihona i mea e pono ai; ma hope o ka heluhelu ʻana o kahi scanner i nā helu i loko o ke code, pono e hoʻopili ʻia lākou i ka lā huahana a i ʻole ka lā kumu kūʻai, a i ʻole nā ​​​​ʻike ʻē aʻe.

N: He aha ka a2D barcode?

A: 2D barcode scanner no ka hoʻopaʻa ʻana i ka ʻike me nā kiʻi geometric i puʻunaue ʻia ma ka ʻeleʻele a me ke keʻokeʻo e like me kekahi kānāwai. o ka lolouila. I ka wa e pili ana i ka mea koho, 2D barcodes pinepine ka makemake o na kanaka ma muli o ka nui o ka ike a 2D barcode hiki ke paʻa i ka hoohalike me 1D.
