IKhowudi ye-2D, eyaziwa ngokuba yibhakhowudi ye-dimensional-dimensional, yindlela entsha yokufaka ikhowudi kunye nokugcina ulwazi lwedatha oluphuhliswe kwisiseko sebhakhowudi ene-dimensional.Iikhowudi ze-QR zinokubonisa ulwazi olwahlukeneyo olunje ngoonobumba baseTshayina, imifanekiso, iminwe kunye nezandi.Ngenxa yokufundwa komatshini olomeleleyo, ukuskena okulula kunye nokusetyenziswa, kunye nokugcinwa kolwazi oluthe kratya, iikhowudi ze-QR zisetyenziswa ngokubanzi kwindawo yokugcina izinto, ukuthengisa, ishishini lenkonzo, ukulawulwa kweziyobisi, ukugcinwa kolwazi lwe-reagent yebhayoloji, ukuqinisekiswa kwesazisi, ukuleyibheli kwemveliso, ukuthuthwa ngobuchule. isetyenziswa kakhulu kwintsimi yokhuseleko.

Iikhowudi ezine-dimensional zingohlulwa ikakhulu zibe ziintlobo ezipakishiweyo kunye nodidi lwematrix ngokwemigaqo yokhowudo eyahlukeneyo.Iikhowudi ezimbini eziqhelekileyo zibandakanya ikhowudi ye-QR, i-PDF417, ikhowudi ye-DM, njl.

Ikhowudi yeQR
Ikhowudi ye-QR yikhowudi ye-matrix ene-dimensional-dimensional ene-ultra-high-speed, iimpawu zokufunda ezijikelezayo, kwaye ngoku yeyona isetyenziswa kakhulu.Ngokuqhelekileyo isetyenziselwa ukuhanjiswa kunye nokulawulwa kwemveliso ye-industrial automation.Kubomi bemihla ngemihla, iikhowudi ze-QR zikwasetyenziselwa iikhowudi zokukhwela ibhasi kunye ne-subway kunye namakhadi eshishini e-WeChat QR.

 

 

PDF417
I-PDF417 yikhowudi ye-QR egciniweyo, eyifayili yedatha ephathekayo enoxinano oluphezulu kunye nomxholo wolwazi oluphezulu, kwaye ulwazi olugciniweyo alukwazi ukubhalwa kwakhona.Ngenxa yomxholo omkhulu wolwazi kunye nemfihlo eyomeleleyo kunye neepropathi ezichasene ne-counterfeiting yale khowudi ye-dimensional, isetyenziswa kakhulu ekugqithiseni, iipasipoti kunye namanye amaxwebhu.

 

 

Ikhowudi yeDM
Ikhowudi ye-DM yikhowudi ye-matrix ene-dimensional, esebenzisa kuphela i-perimeter yokuchonga kwaye inokhuseleko oluphezulu, ngoko isetyenziswa rhoqo kwintsimi yokhuselo lwelizwe kunye nokhuseleko, ukuphawula iindawo ze-aerospace, njl.

 

Njengoko izicelo zekhowudi ye-QR zisiya zithandwa ngakumbi, abashicileli kunye neeskena zekhowudi ye-QR zokuprinta iikhowudi zeQR nazo ziye zaba yimfuneko.
