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

He kiʻi kiʻi kiʻi ke kiʻi paʻi kiʻi 2D (ʻelua-dimensional) e mālama i ka ʻike ma ka ʻaoʻao e like me ka hana ʻana o ka pahu pahu hoʻokahi, a me ke kū pololei. ʻO ka hopena, ʻoi aku ka kiʻekiʻe o ka hiki ke mālama i nā barcode 2D ma mua o nā code 1D. Hiki i ka pahu 2D hoʻokahi ke hoʻopaʻa i 7,089 mau huaʻōlelo ma kahi o ka mana 20-character o kahi barcode 1D. ʻO nā code pane wikiwiki (QR), e hiki ai ke komo i ka ʻikepili wikiwiki, he ʻano o ka barcode 2D.
Hoʻohana ka poʻe kelepona Android a me IOS i nā barcode 2D i kā lākou mau barcode scanner i kūkulu ʻia. Kiʻi ka mea hoʻohana i kahi barcode 2D me kā lākou pahupaʻikiʻi kelepona, a ʻo ka mea heluhelu i kūkulu ʻia e wehewehe i ka URL i hoʻopili ʻia, e alakaʻi pololei ana i ka mea hoʻohana i ka pūnaewele pili.
Hiki i kahi barcode 2D hoʻokahi ke paʻa i ka nui o ka ʻike ma kahi wahi liʻiliʻi. Hōʻike ʻia kēia ʻike i ka mea kūʻai aku, mea hoʻolako a mea kūʻai paha ke nānā ʻia ke code e nā mea nānā kiʻi kiʻi 2D a i ʻole nā ʻōnaehana ʻike.
Hiki i nā ʻike ke komo: inoa mea hana，Helu hui / hīnaʻi，Paona huahana，Hoʻohana e / maikaʻi loa ma mua o ka lā，Grower ID，Helu GTIN，Helu Serial，Kumukuai

Nā ʻano o nā barcode 2D

Aia nā ʻano nui o2D barcode scannerhōʻailona: GS1 DataMatrix, QR code, PDF417
ʻO GS1 DataMatrix ka mea maʻamau 2D barcode format. Ke hoʻohana nei ʻo Woolworths i ka GS1 DataMatrix no kāna mau barcode 2D.
ʻO GS1 Datamatrix 2D barcodes he mau hōʻailona paʻa i hana ʻia me nā module square. Ua kaulana lākou no ka hōʻailona ʻana i nā mea liʻiliʻi e like me nā huahana hou.

1. Ka wāwahi ʻana i ka GS1 DataMatrix

1. Hoʻokaʻawale ʻia nā ʻāpana: ʻo ke kumu ʻike i hoʻohana ʻia e ka scanner e ʻimi i ka hōʻailona, a me ka ʻikepili i hoʻopaʻa ʻia.
2.Even helu o na lalani a me na kolamu
3.A kukui 'square' ma ka luna akau-lima kihi
4. Hiki ke hoʻopili i ka ʻikepili lōʻihi loli - ʻokoʻa ka nui o ka hōʻailona e like me ka nui o ka ʻikepili i hoʻopili ʻia
5. Hiki iā ia ke hoʻopaʻa inoa a hiki i 2335 mau huaʻōlelo alphanumeric a i ʻole 3116 helu (ma ka huinaha)

2. QR code

Hoʻohana mua ʻia nā code QR no ka hoʻopili ʻana i nā pūnaewele URL a ʻaʻole hoʻohana ʻia i kēia manawa no ke kūʻai aku. Hoʻohana pinepine ʻia lākou no ka hoʻopili ʻana i nā mea kūʻai aku, no ka mea hiki ke heluhelu ʻia e nā kāmela kelepona.
Me ka hoʻohana ʻana i ka GS1 Digital Link, hiki i nā code QR ke hana ma ke ʻano he mau barcodes e ʻae i ka hoʻopili ʻana o nā mea kūʻai aku a me ka nānā ʻana i ke kumukūʻai, e hoʻopau ana i ka pono o nā code he nui e lawe ana i kahi wahi hoʻopaʻa waiwai.

3.PDF417

ʻO PDF417 kahi barcode 2D e hiki ke mālama i nā ʻikepili binary like ʻole, me nā alphanumeric a me nā mea kūikawā. Hiki iā ia ke mālama i nā kiʻi, nā pūlima a me nā manamana lima. ʻO ka hopena, hoʻohana pinepine ʻia ka hōʻoia ʻike, ka hoʻokele waiwai a me nā lawelawe kaʻa. ʻO ka ʻāpana PDF o kona inoa mai ka huaʻōlelo "portable document file." ʻO ka ʻāpana "417" e pili ana i kona mau kaola ʻehā a me nā hakahaka i hoʻonohonoho ʻia i loko o kēlā me kēia ʻano, he 17 mau huaʻōlelo.

Pehea ka hana ʻana o nā barcode?

Ma ka pōkole, ʻo ka barcode kahi ala e hoʻopili ai i ka ʻike i loko o kahi hiʻohiʻona hiʻohiʻona (kēlā mau laina ʻeleʻele a me nā wahi keʻokeʻo) hiki ke heluhelu ʻia e kahi mīkini.
ʻO ka hui pū ʻana o nā pahu ʻeleʻele a me ke keʻokeʻo (kahi i ʻōlelo ʻia he mau mea) e hōʻike ana i nā ʻano kikokikona like ʻole e hahai ana i kahi algorithm i hoʻonohonoho mua ʻia no kēlā barcode (ʻoi aʻe ma nā ʻano barcode ma hope). Amīkini paʻi pāʻāluae heluhelu i kēia ʻano o nā kaola ʻeleʻele a me ke keʻokeʻo a unuhi iā lākou i kahi laina hoʻāʻo i hiki i kāu ʻōnaehana kūʻai kūʻai ke hoʻomaopopo.

Inā makemake ʻoe a nīnau paha i ke koho ʻana a i ʻole ka hoʻohana ʻana i kekahiQR code scanner, hookipa maikāhea iā mā˚ou!MINJCODEua paʻa i ka noiʻi a me ka hoʻomohala ʻana i ka ʻenehana scanner bar code a me nā lako noi, ʻo kā mākou hui he 14 mau makahiki o ka ʻoihana ʻoihana ma nā ʻoihana ʻoihana, a ua ʻike nui ʻia e ka hapa nui o nā mea kūʻai!
