Khodi ya 2D, yomwe imadziwikanso kuti barcode yamitundu iwiri, ndi njira yatsopano yosungira ndikusunga zidziwitso za data zomwe zimapangidwa pamaziko a barcode ya mbali imodzi.Ma QR code amatha kuyimira zidziwitso zosiyanasiyana monga zilembo zaku China, zithunzi, zolemba zala ndi mawu.Chifukwa champhamvu yowerengera makina, kusanthula kosavuta ndikugwiritsa ntchito, komanso kusungirako zambiri, ma QR code amagwiritsidwa ntchito kwambiri posungira zinthu, kugulitsa, kugulitsa ntchito, kuyang'anira mankhwala, kusungirako zidziwitso zabiological reagent, kutsimikizira ID, kulemba zinthu, mayendedwe anzeru, ndi amagwiritsidwa ntchito kwambiri m'munda wachitetezo.

Ma code amitundu iwiri amatha kugawidwa m'mitundu yokhazikika komanso mtundu wa matrix molingana ndi mfundo zamitundu yosiyanasiyana.Zizindikiro zodziwika bwino za mbali ziwiri zimaphatikizira kachidindo ka QR, PDF417, DM code, ndi zina zotero. Zizindikiro zosiyana zamitundu iwiri zimagwiritsidwa ntchito pazochitika zosiyanasiyana malinga ndi makhalidwe awo.

QR kodi
Khodi ya QR ndi kachidindo kakang'ono kawiri kokhala ndi liwiro lokwera kwambiri, zowerengera mozungulira, ndipo ndiyomwe imagwiritsidwa ntchito kwambiri pakadali pano.Nthawi zambiri amagwiritsidwa ntchito poyang'anira mayendedwe ndi kasamalidwe ka mafakitale.M'moyo watsiku ndi tsiku, manambala a QR amagwiritsidwanso ntchito pamabasi ndi ma mayendedwe apansi panthaka komanso makhadi abizinesi a WeChat QR.

 

 

Chithunzi cha PDF417
PDF417 ndi nambala ya QR yopakidwa, yomwe ndi fayilo yosunthika yokhala ndi kachulukidwe kwambiri komanso zambiri zambiri, ndipo zomwe zasungidwa sizingalembedwenso.Chifukwa chazidziwitso zambiri komanso chinsinsi champhamvu komanso zotsutsana ndi zabodza za code iyi yamitundu iwiri, imagwiritsidwa ntchito kwambiri pamapasipoti okwera, mapasipoti ndi zolemba zina.

 

 

DM kodi
DM code ndi matrix awiri-dimensional code, yomwe imangogwiritsa ntchito perimeter kuti izindikiritse ndipo imakhala ndi chitetezo chokwanira, choncho imagwiritsidwa ntchito nthawi zambiri pachitetezo cha chitetezo cha dziko, kuyika zizindikiro zamlengalenga, ndi zina zotero.

 

Pamene mapulogalamu a QR code akuchulukirachulukira, osindikiza ndi ma QR code scanner kuti asindikize ma QR code nawonso akhala ofunikira.
