2. Kuaj cov yam ntxwv thiab kho qhov muag
Yuav tsum muaj qhov sib txawv ntawm qhov ci ntawm cov kab thiab keeb kwm ntawm barcode (piv txwv li, siab qhov sib piv). Tsis txaus ntseeg (xws li qhov sib txawv me me hauv kev xav ntawm cov kab thiab cov chaw) tuaj yeem ua rau cov khoom siv scanning, uas feem ntau yog tshwm sim los ntawm cov khoom tsis zoo, lossis tsis tsim nyog xim xim sib txuam.

Ib qho ntxiv, sib txawv ntawm cov kua mem kua tuab vim li cas cov txheej txheem luam tawm (xws li offset luam ntawv, graver printing) kuj tseem tuaj yeem cuam tshuam nrog Barcode duraby.
