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

Barcode ya 2D (yonse-awiri) ndi chithunzi chojambula chomwe chimasunga zambiri mopingasa monga momwe ma barcode amachitira, komanso molunjika. Zotsatira zake, kusungirako kwa ma barcode a 2D ndikokwera kwambiri kuposa ma code a 1D. Khodi imodzi ya 2D imatha kusunga zilembo mpaka 7,089 m'malo mwa kuchuluka kwa zilembo 20 za 1D barcode. Makhodi a Quick Recond (QR), omwe amathandizira kuti data ifike mwachangu, ndi mtundu wa barcode wa 2D.
Mafoni am'manja a Android ndi iOS amagwiritsa ntchito ma barcode a 2D pamasinala awo a barcode omangidwira. Wogwiritsa amajambula barcode ya 2D ndi kamera ya foni yam'manja, ndipo wowerenga wokhazikika amatanthauzira ulalo wosungidwa, ndikumutsogolera wogwiritsa ntchito patsamba loyenera.
Barcode imodzi ya 2D imatha kusunga zidziwitso zambiri pamalo ochepa. Chidziwitsochi chimawululidwa kwa wogulitsa, wogulitsa kapena kasitomala pamene code ikuyang'aniridwa ndi zojambula zojambula za 2D kapena machitidwe a masomphenya.

Mitundu yama barcode a 2D

Pali mitundu ikuluikulu ya2D barcode scannerchizindikiro: GS1 DataMatrix, QR code, PDF417
GS1 DataMatrix ndiye mtundu wodziwika bwino wa barcode wa 2D. Woolworths pakali pano akugwiritsa ntchito GS1 DataMatrix pama barcode ake a 2D.
Ma barcode a GS1 Datamatrix 2D ndi zizindikiro zophatikizika zopangidwa ndi masikweya ma module. Amatchuka polemba zinthu zazing'ono monga zokolola zatsopano.

1.Kuphwanya GS1 DataMatrix

1.Zigawo zolekanitsa: mawonekedwe opeza omwe amagwiritsidwa ntchito ndi sikani kuti apeze chizindikirocho, ndi data yosungidwa
2.Ngakhale kuchuluka kwa mizere ndi mizati
3.Kuwala 'square' pakona yakumanja kumanja
4.Can encode variable kutalika kutalika - kukula kwa chizindikiro kumasiyana malinga ndi kuchuluka kwa deta yosungidwa
5.Ikhoza kusindikiza mpaka zilembo za alphanumeric 2335 kapena manambala 3116 (mu squareform)

2.QR kodi

Ma code a QR amagwiritsidwa ntchito polumikizana ndi masamba a URL ndipo pano sagwiritsidwa ntchito pogulitsa. Nthawi zambiri amagwiritsidwa ntchito pakuyika zoyang'ana ndi ogula, chifukwa amatha kuwerengedwa ndi makamera a smartphone.
Pogwiritsa ntchito GS1 Digital Link, manambala a QR amatha kugwira ntchito ngati ma barcode amitundu yambiri omwe amalola kuti ogula atengeke komanso kuyang'ana mitengo, kuchotseratu kufunikira kwa ma code angapo kutenga malo ofunikira.

3.PDF417

PDF417 ndi barcode ya 2D yomwe imatha kusunga zambiri zamabina osiyanasiyana, kuphatikiza zilembo ndi zilembo zapadera. Ithanso kusunga zithunzi, siginecha ndi zidindo za zala. Zotsatira zake, kutsimikizira zidziwitso, kasamalidwe kazinthu ndi ntchito zamayendedwe amazigwiritsa ntchito nthawi zambiri. Gawo la PDF la dzina lake limachokera ku mawu akuti "portable document file." Gawo la "417" limatanthawuza mipiringidzo yake inayi ndi mipata yokonzedwa mkati mwa chitsanzo chilichonse, chokhala ndi zilembo 17.

Kodi ma barcode amagwira ntchito bwanji?

Mwachidule, barcode ndi njira yolembera chidziwitso kukhala mawonekedwe owoneka (mizere yakuda ndi malo oyera) omwe makina (chojambula cha barcode) amatha kuwerenga.
Kuphatikiza kwa mipiringidzo yakuda ndi yoyera (yomwe imatchedwanso zinthu) imayimira zilembo zosiyanasiyana zomwe zimatsata ndondomeko yokhazikitsidwa kale ya barcode (zambiri pamitundu yama barcode pambuyo pake). Abarcode scanneradzawerenga chitsanzo ichi cha mipiringidzo yakuda ndi yoyera ndikuwamasulira kukhala mzere woyesera umene malo anu ogulitsa malonda angamvetse.

Ngati muli ndi chidwi kapena funso pakusankha kapena kugwiritsa ntchito chilichonseqr kodi scanner, mwalandiridwa kuLumikizanani nafe!MINJCODEyadzipereka ku kafukufuku ndi chitukuko chaukadaulo wa barcode scanner ndi zida zogwiritsira ntchito, kampani yathu ili ndi zaka 14 zaukadaulo pantchito zamaluso, ndipo yadziwika kwambiri ndi makasitomala ambiri!
